Product detail
Straight pneumatic die grinder that brings high-speed rotary power to porting, deburring, polishing and light grinding jobs in the workshop. The in-line body with a 6 mm collet takes standard carbide burrs, mounted points and grinding stones, spinning them at high free speed for fast metal removal and smooth surface finishing. A built-in speed regulator lets the operator dial the rpm down for precision work on softer materials or softer abrasives. The compact aluminum housing stays cool even on long runs and reaches into ports, dies and engine components where bulky electric tools cannot fit. Running on shop air, there are no sparks from the motor and no batteries to recharge, making it a dependable daily tool for mold makers, metalworkers and engine shops. The standard 1/4 inch air inlet connects directly to workshop hoses with no special adapters. A tool crib that issues air tools can pair the grinder with a box of mounted points, so the operator collects everything needed for a deburring pass in one trip and the abrasives are replenished with the tool. Welders use it to blend a stop-start bead and to clean spatter from a fillet before paint, and because the collet takes mounted points as well as burrs, the same body handles stock removal and a fine polish.
