The Sigma Jolly Edge Grinder Attachment 37A3PD transforms a standard angle grinder into a precision edge-profiling station. Simply thread the body onto an M14 spindle, set your desired angle with the clearly graded dial, and glide the 8-inch guidance plate along the tile. The result is a consistent bevel line that looks factory-machined, eliminating the risk of uneven hand-held passes that can chip expensive porcelain or natural stone.

Supplied with a Sigma 75B continuous-rim diamond blade, the 37A3PD excels on hard porcelain panels, large-format floor tiles, and stone skirting boards up to 20 mm thick. The rigid aluminum frame absorbs vibration for smoother operation and longer diamond life, while the quick-lock depth knob lets you match the wheel height to any tile thickness in seconds. Ideal for installers, fabricators, and remodelers who want upscale, mitred corners without investing in a full wet-saw miter station.
