SPE-X coating for extremely long service life
The SPE-X coating is an applied multi-layer surface coating that lowers the friction coefficient of the drill, which allows the drill to cut smoother and faster while keeping the friction heat low. SPE-X are specially formulated coatings that allow the cutting edge of the tool to achieve the crucial share. and Schm and Schmability to maintain SPE-X delivers cutting results of the highest quality and durability, increasing the service life by up to 2.5 compared to uncoated bits; prevents high heat and oxidation formation, which has a adverse effect on the performance of the cutting tool, and protects the cutting edge from hard wear material.
