Genuine Bosch 1609B03755 — replacement control knob designed for Bosch mitre saws.

This original Bosch knob commonly fits GCM-series saws, including models listed like GCM 18V-216, GCM 8 SDE, GCM 8 SJL and GCM 800 SJ (alternate formatting: 1 609 B03 755).

It’s a direct-fit, molded replacement knob that restores secure grip and positive adjustment for angle/bevel locking where a stripped, cracked or missing knob prevents safe, repeatable settings; installers report a quick swap with no modification required.

If you need a small, authentic component to get your saw back to working order, this genuine Bosch item is one of the straightforward Bosch power tool parts to replace — a common item among essential power tool parts for mitre saw maintenance.
