04

Ergonomic handle design

The Straight Stone Grinders have strong, rigid handles that are isolated from hydraulic hoses to protect operators’ hands from the heat of the hydraulic flow.

05

Rub pads

Rub pads are fitted to either side of the stone guard, decreasing wear when grinding the ball of rail.

06

Sealed bearings

The tools’ sealed bearings are robust and protected from dirt.
