Body and Hand Grip

The way a circular saw feels in the hand can affect how you can easily use it. For this one, it comes with a hard-plastic hand grip with parts covered in rubber. The rubber will reduce some of the vibrations generated by the unit. With a pair of gloves, you should be good to keep working.

The main material used to make the saw is magnesium. We all know that magnesium is lightweight. This translates to having a lightweight model to work with each time you go through a workpiece. Such a material is also good for boosting the overall durability of the unit.


One thing that stands out for the unit should be that it is easily maneuverable. This is because it feels comfortable in the hand, making it easier to control the unit. Also, it features the best bevel capacity of up to 53 degrees. With stops at 0 and 45 degrees, you can make the quick cuts if the need arises.

The hand grip on this unit is designed to fit in the hand better as compared to some competitor units. Also, it is partially covered in rubber. The aim of using rubber is to reduce the amount of vibrations. The result is that you have a better hand grip. You should consider getting yourself some work gloves to keep the vibrations low.

Also, the blade has up to 24 teeth and carbide tips. This number of teeth helps with achieving clean cuts all the time.


To make it better, the unit comes with the cut-ready system. This type of system allows you to make fine adjustments to the saw and make it more accurate and consistent in the cuts. There is also the anti-snag guard. It is important to maintain the overall smoothness of the operation.

This type of motor can deliver the right power for cutting the thick workpieces. Also, the motor has the dual copper winding. This type of winding is good for ensuring you end up with a cooler motor even if you keep using it for long sessions.
