❓ FREQUENTLY ASKED QUESTIONS

What materials are used in the construction of these button bits?

The bits are manufactured using high-quality Alloy Steel Bar (45CrNiMoV) combined with premium Tungsten Carbide Tips (YK05 or T6) for maximum durability and drilling efficiency.

Which tapered connection degrees are available for order?
