Cemented Carbide Button Instruction For Use

Bits need to be sharpened and serviced like any other cutting tool. The sharper the carbide inserts are, the faster the penetration rate will be. Also, the percussive energy from the hammer or drifter will be transferred into the rock rather than be reflected back into the drill string. This will save excessive "wear and tear" on the drill string components and the drilling machine. Rockmore International recommends re-sharpening bits when the carbide buttons attain flats that are 1/4 (one quarter) of the major diameter.

Drill operators should monitor the condition of the carbides regularly, and frequently. If they do this, they will notice that the machine runs smoother and that the penetration rates are higher with a well maintained bit. Carbide buttons can be sharpened with either portable or stationary grinding machines using grinding pins (cups) or grinder wheels.
