PROSHI 1/4-Inch 90° Angle Air Die Grinder – Compact Pneumatic Grinder

Meet the PROSHI 1/4-Inch 90° Angle Air Die Grinder, a compact pneumatic tool designed for precision finishing in tight spaces. The 90-degree head shifts the attachment axis, letting you reach edges, interiors, and contours that inline tools struggle to touch. With a focus on smooth transitions and controlled material removal, this grinder supports tasks from porting and deburring to soft polishing and delicate engraving. The tool’s polished finish is complemented by a lightweight aluminum body, which reduces operator fatigue during extended sessions, while the rear exhaust helps keep your workspace comfortable and clear. A built-in air regulator and a variable-speed throttle give you gradual ramp-up to high RPM, so you can start with a gentle touch and increase speed as the surface demands. Ergonomics are designed with balance in mind, allowing steady control across long sessions, and the compact footprint helps you maneuver around fixtures, hoses, and fixtures without snagging. While no tool replaces careful technique, this grinder is designed to support precision work with consistent response.
