The sharpening machine is a strong, simple, and safe accessory designed to achieve optimal re-sharpening without compromising any of the structural qualities of the cutting tools. A single movement of the abrasive wheel ensures the original angle and radius of the tungsten carbide cutter are maintained, guaranteeing fast and optimal resharpening. The machine is available in two versions: a bench model with a supporting structure or a lightweight version for easy mounting on rock using a pin. The resharpening machine consists of a pneumatic motor with an integrated centrifugal limiter, a line oiler, a cooling water valve with a flexible hose, and a clamping device for the drill steel (upon request, this clamping device can be pneumatic).
