Rockwell RK3440K VersaCut Circular Saw

Rockwell RK3440K VersaCut Circular Saw

Overview

Rockwell RK3440K VersaCut Circular saw is another excellent product from this well-known household brand from China. One of the key goals of this brand is to make products that are easy to use. This means they can be used not only by those using the saw for professional use but also by those who are just starting out and will be using the product for personal use around the house. The RK3440K has lots of great features and is super lightweight meaning it is very easy to maneuver, even on the more complex of cuts. The laser guide is really well placed and is a great help when you are trying the longer cuts, it ensures you can keep a straight and true cut throughout the length of the cut. This particular model comes with 3 different blades that are super easy to switch out depending on the kind of material that you are looking to cut through. It is one of the best circular saws for cutting wood, but obviously, using the different blades Rockwell have on offer, can allow you to cut through other materials such as tile and metal.

What’s great?

  • As I alluded to earlier, the laser guide is a really great feature on this product. One of the toughest parts about cutting anything is staying in a straight line throughout the cut. The laser really helps to protect you from veering off.
  • The light weight of this model really provides you will ultimate maneuverability. This again is key for accuracy when cutting and of course general ease of use.
  • The RK3440K is considerably smaller and lighter than many of its competitors. This obviously helps with maneuverability also.
  • It has the ability to cut through pretty much any material (as long as you use the correct blade of course). This makes the model extremely versatile.
  • The VersaCut has no setting up. Straight out of the box and you can start using. This is a big plus, especially if you are not overly technical.

What’s not so great?

  • If you are using for industrial or professional tasks, this may be a little small and lightweight.
  • Not too great for angle/bevel cutting. The VersaCut definitely has more prowess cutting in a straight line.
  • When using this model for deeper cuts it can be a little cumbersome. You have to change a number of settings to get into the right position and many users find this a little frustrating.

Conclusion

If you are looking for an easy to use, nimble circular saw for home use then this is perfect for you. Its light weight and great features mean it is perfect for anyone starting out with a bit of DIY or general home improvements. If, however, you are looking for the best circular saw for industrial or professional use this may not be the one for you. I would be looking for something a little more heavy duty and durable for these tasks. You can easily find the best skill saw or other type of saw for this work by continuing to read on.

Makita SP6000J1 6-1/2-Inch Plunge Circular Saw with Guide Rail

Makita SP6000J1 6-1/2-Inch Plunge Circular Saw with Guide Rail

Overview

The Makita SP6000J1 6-1/2-Inch Plunge Circular Saw with Guide Rail is an excellent quality product. If you are having trouble cutting and find that your cuts not fine or precise enough, the Makita has the perfect solution for you. Especially designed to produce precise, splinter-free cuts, the Makita SP6000J1 model 6-1/2” Plunge Cut Circular Saw with 55” Guide Rail is the perfect tool for smooth cutting.

The Makita guide rail saw works by coordinating the blade as such and the 55’’ guide rail to perform precise cuts and reduce tear-out. Combining a powerful motor of 12 AMP with an extensive cutting ability, it incorporates magnesium elements for weight optimization and ensure electronic speed control to maintain a constant level of speed under load for fine, mirror finish cutting. Makita SP6000J1 is a portable alternative to a table saw for select operations, being the ideal tool for use on the jobsite or in a workshop.

With a bevel capacity between -1° to 48° and positive stops at 22.5° and 45°, the Makita SP6000J1 6-1/2’’ Plunge Cut Circular Saw with 55’’ Guide Rail can deliver splinter-free cuts. The saw can smoothly cut the material with minimum tear-out as the blade penetrates the material along the same cutting line whether cutting straight or chamfer. Additionally, should you need to perform close-to-wall cuts, the Makita saw has an 11/16-inch cutting feature for expanded applications. What makes Makita the ideal tool for smooth and precise, mirror finish cutting is its built-in depth stop that allows you to perform a 1/16-inch preliminary cut before the whole material is cut through.

The saw’s 12 AMP direct-drive power motor with smooth start-up and electronic speed control features can guarantee smooth cutting by causing the speed to remain constant under load. Makita can be used for a variety of materials. To optimize performance depending on the material that you need to cut, the 2,500 – 5,200 RPM variable speed dial control allows you to set the speed. Moreover, the integrated torque limiter prevents motor burnout, and its electric brake helps increase productivity.

What’s great?

  • The guide rail is super useful and really helps you to carry out perfect straight cuts every time. Some saws obviously don’t have this feature so this does help the Makita stand out from the crowd.
  • This model is light weight and thus easy to manage/maneuver. Product weight is a big factor with electric circular saw.
  • The product has two convenient bevel settings at both 45 and 22 degrees. There is also a max setting of 48 degrees should you need to go that little bit further.
  • The easy to use dial to vary the speed and the soft starting functionally are great, especially if you are a novice to using a compact circular saw.
  • The large handle located conveniently on the top of this corded circular saw is an excellent feature. It really helps to provide good control and confidence while using.
  • The stopper to control the depth of your cut is really useful and also critical to the quality and accuracy of your cutting. This is one of our favorite qualities in this particular saw.

What’s not so great?

  • We didn’t find this model that great for the smaller jobs. Cutting thin wood or other materials can be a little challenging if you haven’t used a circular saw before or you are relatively new.
  • Not great for the professional. This item is best suited to beginners.

Conclusion

This model from Makita is tailor made for newbies. If you are looking for best circular saw for the money and you haven’t purchased a saw like this before then you cannot go far wrong with this one. The functionality across the board is very easy to pick up and it lends itself well to someone who is not an expert in the field of cutting with power tools. The best circular saw for DIY and home work of any kid is one that can be used straight out of the box by someone who has never done it before, and this definitely fits that description. As you can probably ascertain though, if you are a seasoned professional or you plan to use this product in the work place this may well come up short. You are better to invest a little more and use a brand or model that is a bit more durable, has more functionality and is tailored more towards industrial usage.

Comprehensive Buyers Guide on what to consider when buying a circular saw or compact circular saw for home or professional use

Top 10 factors to consider when buying and checking circular saw ratings

1. Budget

Setting or deciding on the price that you would like to pay for your circular saw is probably the most important part of the buying process. Are you looking for a cheap circular saw and thus will be searching for the best budget circular saw? Or is price less of an issue and therefore you will be seeking out the best quality circular saw or the best value for money circular saw. Luckily there are a wide variety of different brands and models available at different prices online so you should have no problem at all locating a good quality worm drive saw or sidewinder saw that suits both your functionality requirements and your budget. It is important to lay out your costs and pricing limitations before you start your search though as this will really help you to hone in on your perfect product.

2. Worm Drive or Direct Drive saw?

Should you be choosing a worm drive or gear driven model or a side winder or direct drive option? This is one of the first questions that you will need to ask yourself when you are picking the right circular saw for sale. To be brutally honest, it is really down to personal preference but I tend to lean towards the direct drive options and these are favored by the majority of professionals. You will also need to decide whether you want a left or right handed saw, this will of course be pretty easy to choose. Although, some people that are left handed do choose a right handed saw and vice-versa. Some additional factors to bear in mind are the blade choices and of course the quality and material of the base plate (I will cover this a little more in depth later on). Some of the blade options are sharp blades, different curved blades, masonry blades, wood cutting blades and metal cutting blades.

3. The position and accuracy of the cut line indicator

This is the small notches (usually two) in the front of the saws baseplate. Helps you to align your blade with the cut line. It is extremely important to know that your blade is on the money both 45 degrees and 90 degrees. A good quality marker aligns both sides of the cutting plate. This allows you to cut to the right or the left of your line, as per your preference. If your cut line indicator is over sized or misaligned you may have to supplement with your own marker (pen). This can be a little annoying and obviously isn’t as accurate as if you had an accurate cutline indicator so definitely something to consider seriously before you make your purchasing decision. Comparing the different cut line sizes and locations is key. The best circular saw blade will align perfectly with the markers and create the perfect cut every time.

4. Cordless or corded?

In years gone by buying a cordless circular saw wouldn’t have really been a viable option due to the limited battery life and power they had. However, in recent years the battery quality and the output of these options has been increased dramatically making them a strong contender. If you are using the saw for personal use around the home or the odd job here and there a cordless saw could be a great option for you. Due to the limited torque and the fact you are inhibited by the battery life (even though it is better than is was), you probably should stick with a corded circular saw model if you are a serious user or using the saw for work.

5. The blade visibility when you are cutting

You will notice on some of the top circular saw models available on today’s market place you will have poor visibility through to your cutting line when you are operating your saw. You need to make sure that when you have compared all the products you opt for one that has a clear window through all the appendage of the saw to the cutting point. This will really help you to cut accurately and will also mean you get better efficiency when working.

6. The bevel functionality

Whether you are a regular user or a novice the use of the bevel will no doubt come into play regularly. For this reason it is important to obtain a top circular saw that has an excellent and easy to use bevel function. Some of the key things to take in to consideration when comparing is the comfort when operating, the ability to move the bevel beyond 45 degrees and the presence of clear and engraved numbers for ease of use/visibility. Although, the bevel function this isn’t often used for simple jobs, when you are carrying out more complex work like roofing it is absolutely critical. Comfortable to use and a locking function that is nice and secure are the most important in my opinion.

7. The material for your base plate

The quality of the base plate that you have can literally define how true and consistent your cuts are. You need to ensure that when scanning through best worm drive circular saw reviews and other product reviews you opt for a saw that is completely flat across both the length and width. You also need to look for a straight left edge (or right) to run against a guide, this will really help with your cutting accuracy.

There are a number of different materials that your base plate can be crafted from, here are a few of the options: Stamped aluminum base plates will be light but the problem with these is they are easily bent if you happen to drop them. They can however be fixed by bending them back into shape, but you may never get them back to completely flat again. Cast aluminum or magnesium base plates are much stiffer. The issue with these is, if dropped can easily crack and once cracked they cannot be fixed and must be replaced which can be quite costly. Fiber reinforced plastic base plates are super light and strong but make sure thick enough to be stiff as they have much more flex than metal alternatives. I would definitely go for the fiber reinforced options if you can though, these are the best of the 3 mentioned in my opinion.

8. Guard retraction functionality and usage

The guard retraction unit or cover is the part of the saw that protects the user from being cut or injured by the circular saw blade. This is when the saw has been switched off and is no longer cutting but the saw blade is still rotating. You should be looking for a guard retraction unit that is very smooth and thus has no chance of getting stuck midway through a cut, this can be very frustrating. When reviewing the available circular saws within your price range, seek out ones that have a good sized lobe above the leading edge. These are among the best for me. Be sure to stay away from the best circular saws for home use or professional use that have rough or sharp leading edges. These can easily get stuck when sawing especially on wooden surfaces, you definitely do not want this.

9. Saw to base plate connection

This is the pivot point on the saw where the motor and handle assembly meets the base plate. This allows you to plunge for depth and pivot side to side for bevel cuts. The best small circular saw options and the larger more industrial models have a saw to base plate connection that is in line with the rear handle. Also, front handle that is low and also inline this provides stability. You can often find these useful traits with a good quality table top circular saw.

10. Placement and operation of the depth adjustment lever

Outboard levers make this functionality much easier to access and allow you to keep a hand on the handle while adjusting. The presence of a rubber covered or thick rounded lever can also really help to make your saw more pleasant to use. The depth scale on your model should be clearly marked and easy to read. This will assist you in being more efficient when cutting.

Difference between a worm drive saw and a sidewinder saw?

The key difference between these two different kinds of saws is the position of the motor and how the motor transfers the power through the gears and ultimately through to the blades.

The sidewinder models use a spur gear that is in line with the spinning blade, thus the engine has to be located on the side of the saw. This means you get an extremely fast blade movement on this kind of saw, usually in the region of 6000RPM. These saws are usually fairly compact and lightweight due to the motor location in relation to the blade.

With a worm drive saw the motor is located at the rear of the tool. This upshot of this is the power is sent through to the blades using a pair of gears that are oriented at a 90 degree angle to each other. This reduces the speed of the blades down to somewhere in the region of 4500 RPM but the torque is greatly increased with this variety of handheld circular saw. In light of the design for this variance of saw the models are usually much longer than the sidewinder options and they are also much heavier because of the additional weight of the gears.

You will generally find that a sidewinder saw will have the blade located on the right and a worm drive will have the blade on the left. This obviously means that if you are right or left handed it will really affect how you use the tool and of course your sightline through to the cutting line. Most argue that the positioning of the blade on the sidewinder is great for both left and right handed users as it keeps both hands safely out of harm’s way. The downside with this model is the line of side to the cut.

The additional length of the worm drive really helps with the longer cuts and the weight of these tools can be leveraged to assist with hand held cuts. One other thing to consider with the worm drive saws is the fact you will need to add oil fairly regularly to keep the gears well lubed and functional. This is a hassle you won’t have with a sidewinder.

So, which is the best? The honest answer unfortunately, is neither. Both saw types have pros and cons and it really comes down to the way you prefer to work and what you will be cutting. The great news is that most brands now manufacture and sell both types of saw, so you should have no problem purchasing from your favorite brand.
