Product Specification

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.

William ★★★★★

This straight pneumatic die grinder keeps a consistent speed even under heavy pressure, which makes smoothing out welds much faster than my old one. The trigger response is crisp and it hasn't bogged down once since I got it.

Eli K. ★★★★★

I’ve been using this die grinder for a few weeks now on various metal projects, and the high-speed precision grinding really cuts through tough material quickly. The build feels solid and the grip is comfortable even during longer sessions. It’s become an essential tool in my shop.

Avery ★★★★★

The throttle response is really smooth on this grinder, making detailed work much easier. It handled my deburring jobs without any stalling, and it feels solid in the hand. Exactly what I needed for precision grinding tasks.
