STRAIGHT PNEUMATIC DIE GRINDER

Benchmark Abrasives Straight Pneumatic Die Grinder is engineered for high-speed precision grinding with maximum reach and ergonomic balance. Designed to power through metal prep and cleanup tasks, it delivers the torque and control fabricators rely on every day.

The elongated profile provides excellent line-of-sight and maneuverability for inside corners, edge work, and hard-to-reach welds. A comfortable anti-slip grip stabilizes the tool in your hand, while the smooth throttle lever helps maintain consistent speed during delicate grinding or full-force deburring.

Constructed with hardened steel internal components and wear-resistant bearings, this grinder is built for long-term performance in demanding shops. Paired with the right tooling—carbide burrs, abrasive cartridge rolls, flap wheels, and more—it becomes a versatile workhorse for shaping, smoothing, and finishing metal.

When you need accuracy, power, and a light footprint, this straight die grinder steps up and does the job right.
