Up to 12 inches less workspace will be taken due to its Axial Gliding System that provides wide cross cuts unlike the traditional rail setup. Square lock quick-release fences offer easy, precise alignment at 90 degrees angle at the saw table. Hence, no adjustments required.

The bevel capacity can cut the material at angles ranging from 0 to 47 degrees to both the left and right by simultaneously marking the detent and pitch roof angles static at the common angles. The saw features bevel detents at 0, 33.9, and 45 degrees for both left- and right-facing cuts, and it includes a high visibility dual-bevel scale.

At first, I will speak about accuracy of this chop saw. I have used this Axial Glide Miter Saw on large timbers. I was surprised by its great capacity in cutting largest timbers with a real delicate touch in different angles with perfect accuracy.

The Miter cuts are super accurate and smooth as there are no large rails. And also no need to worry about re-calibrating the unit and inaccuracy of cuts, as it did not have rail wear which need frequent calibration.

Axial glide system

Next, Bosch GCM12SD has great quality axial glide system which is the smoothest gliding miter saws I have ever seen. The Advantage of having the axial glide system is smooth gliding and reduced space. Bosch has taken both of these features with this design. Check cheap tool boxes to buy.

I used to work hard with other traditional miter saws whose slides are exposed to dust and sticking grease on the rails. In this model, I did not face this problem as there are no exposed grease joints.

Some buyers are worried about blade wobbling, when you make bevel cuts at 45 degrees. I have noticed this type of wobble on all 12 inch miter saws.

Quality Miter cuts

A good miter saw has to make high quality cuts throughout the day at great speed. Bosch has powerful motor of 1800 watt capacity to take care of quality cuts at high speed. It can easily complete toughest cuts and its motor life will be more without more effort.

This capacity is large compared to the lower end of the market, and as you go up in price range this tends to grow. This unit is at the top end of cutting capacity for a mitre saw.

The number of cuts at different angles can be achieved very quickly with a fast push button angle setting. You can easily change Blade in the GCM12SD with the help of spindle lock to keep the machine working quickly.

Safety Features

Safety is the first priority while working in job sites. Bosch taken care this well by using sizeable blade cover and keeping the spinning blade away from the user.

Both Right and left hander’s can use this comfortably by locking handle in different positions. The saw’s controls are easy to access and simple to use without any need of moving having around a lot. This is an important feature you should look in terms of safety aspect.

Dust collection

Bosch has supplied integral bag along with this unit, so dust extraction is managed well. And also they have given flexibility to connect an external dust extraction system to collect dust on a large scale in less time. This makes working surrounding environment clean and healthy.

Bosch Miter saw spares

It is very important to repair and replace spare parts quickly and effectively when machine got failed. For that you need good dealers who sell spare parts. Bosch has a huge dealer network and a lot of readily available spare parts that can be brought easily.

The GCM12SD has many accessories that are available for different types of job. It has different style blades and attachments for cutting various types of materials including metals.

The arm of the saw is made from strong and rigid aluminum that gives enough strength to cut even metal with great accuracy.

Space Saving

Space saving is another advantage of this chop saw, as it can cut big wooden blocks without the need for long rails. Due to this, you can use this in the smallest workshops and building sites.
