With the special cutting edge geometry, the diamond ground cutting zone and the carbide plate the GOLDCRAFT is suitable for nearly all materials to be drilled. The very hard tungston-titanuim carbide tip stands for an extremely wear resistant drill bit.
Universal drill bit GOLDCRAFT
The GOLDCRAFT is suitable for almost all materials to be drilled due to the special cutting edge geometry and the diamond-ground cutting surfaces of the carbide tip. The very hard tungsten-titanium carbide tip makes the drill bit extremely wear resistant.
Regrinding of the carbide tip becomes necessary during prolonged use
Higher wear of carbide tip when drilling in abrasive materials
Only use sharp drill bits for drilling in porcelain, ceramics, glass
