Features of the Bosch gcm 12 gdl


The motor on the GCM12GDL chop saw is a 2000-watt electric motor. The powerful motor can take on large construction timbers. This model is the 240-volt model that uses a mains power supply. It is worth paying the extra for this power if you need a hard-working mitre saw.

Cutting capacity

This saw cuts large pieces of material. The motor and blade size is well-balanced to take on some of the toughest cuts. The cutting capacity at 0 degrees is 104 mm (4.1 inches) by 341 mm (13.4 inches). That extra inch allows a new set of timbers for large construction jobs. The capacity makes it an ideal saw for roofers and building wood frame buildings.

Bevel and mitre angles

This double bevel saw allows tight angles to be cut accurately. Mitre angles are 52 degrees on the left and 60 degrees on the right. The bevel angles are 47 degrees on both the left and right sides.


One of the key features this model have is the compact design using dual arms to slide the saw rather than guiding rods. The arms fold back into the back of the saw when it is not being used and extend out for the larger cuts., making it ideal for tighter spaces and workshops where tools need to be kept small. The GCM12 GDL dimension is 673 cm depth by 822 cm in length and 686 in height. It is a large unit, but for the cutting capacity, it is compact. It still weighs in at a heavy 32kg.

Double laser guide

The double laser guide offers you the accuracy of cuts, visibility, and a better way of following wider cuts. That is a high-end feature you will not find on many other mid-range saws.
