WORKPRO Air Angle Die Grinder — 90° Pneumatic Grinder, 1/4-Inch Collet, 20,000 RPM

Unlock versatile performance with the WORKPRO Air Angle Die Grinder

Engineered to reach tight spaces and curved surfaces, this 90-degree grinder combines compact ergonomics with robust air-powered performance. It ships with both a 1/4" and a 1/8" collet, so you can switch quickly between grinding, deburring, porting, and polishing tasks without changing tools. A safety-lock throttle helps prevent accidental starts, giving you more control on demanding projects.

Designed for control, comfort, and clarity

Measuring just over six inches and weighing about a pound, the tool is built for one-handed grip and prolonged use. The ergonomic form minimizes fatigue while delivering steady, precise reactions to your movements. A rear exhaust keeps airflow away from your face and work surface, helping you stay focused on the job at hand. For added protection, an air inlet filter helps keep the tool clean in dusty environments.

Power and performance you can rely on

When connected to a suitable air compressor, the grinder delivers up to 20,000 RPM, enabling fast material removal and precise shaping. Operating at around 90 psi (6.3 bar) with an air flow of 85.5 l/min (3 cfm), it maintains strong speed through a variety of applications. A note on setup: apply sealant tape to reduce air leaks, and remember to remove the DUST PLUG before connecting the air supply.
