Overview
The Bosch GCM12SD is a corded 12 inch sliding compound miter saw running on 120 volts with an 1800 watt motor at 4000 RPM. At 65 pounds, it is a benchtop machine built for trim, framing lumber, and stock up to 12 inches with a carbide-tipped blade.
Bosch markets the GCM12SD line around its glide arm system, which lets the saw reach a wide crosscut without the long rail track that most sliding miter saws need behind the fence, an advantage in a shop or garage with limited wall clearance. The 65 pound weight reflects a full-size stationary tool, not something meant to move between jobsites daily.

- 1800 watt motor at 4000 RPM
- 120 volt corded electric power
- 65 pound stationary design
Who it's for
Suits a home workshop, remodeling contractor, or trim carpenter who needs wide crosscuts on a bench and has space and outlet capacity for a corded 1800 watt tool. It is not built for someone wanting a light saw for occasional jobsite carrying.
Strengths and trade-offs
Drawn from this product's published specifications.
- 12 inch capacity handles wide crosscuts
- 1800 watt motor for dimensional lumber and trim
- Glide arm design saves rear clearance versus rail-track saws
- 65 pounds, not meant for frequent transport
- Corded, requires a 120 volt outlet
Performance notes
The 1800 watt motor spinning at 4000 RPM through a 12 inch carbide-tipped blade is sized for cutting dimensional lumber and trim stock cleanly. Bosch's glide arm mechanism replaces the exposed rails of a typical sliding miter saw, so crosscut capacity comes from an axial glide system rather than a long rail extending behind the fence, which matters if your bench sits close to a wall. The 65 pound weight and roughly 32 by 27 by 27 inch footprint mean it needs a dedicated spot on a bench or stand.
