The Micro Die Grinder operates at 60,000 RPM, making it ideal for high-speed deburring, fine edge finishing, and light contouring when used with a rotary burr. Its 3 mm collet accepts a wide range of carbide tools for post-machining cleanup.
With an overall length of just 140 mm, the tool is designed to work inside dies, cavities, or tight-profile components where larger grinders can’t reach. Its lightweight build supports precise tool control.
Driven by a 1/4″ BSP air inlet, the grinder maintains consistent rotation at 60,000 RPM, delivering smooth material engagement with minimal surface damage. It operates efficiently with a 6.35 mm air hose and regulated pressure line.
The tool is equipped with a 3 mm collet chuck, suitable for standard mounted points, burrs, and stones. It integrates easily with existing workshop setups using a 1/4″ BSP connection and standard 6.35 mm ID air hose.
Weighing only 0.24 kg (approx.), the AP-60 reduces operator fatigue during extended finishing work. Its balanced construction ensures controlled handling across production or toolroom settings.
Designed for detailed finishing tasks, the Micro Die Grinder is suited for operations that demand controlled grinding in restricted areas. It is frequently deployed in industrial settings that involve post-machining cleanup, deburring, and surface refinement.
