Best Valyriantool Twist Drill Bits in 2026

Why settle for standard HSS bits that dull the moment they touch hardened steel? The VALYRIANTOOL M35 cobalt set is a serious upgrade for anyone tired of fighting through stainless steel or cast iron. These bits utilize a 5% cobalt blend, making them significantly harder and more wear-resistant than typical 4241 HSS alternatives. During testing, the 135° split point proved essential because it bites into the material immediately, eliminating that frustrating 'walking' effect and removing the need for a center punch. The fully ground spiral grooves do a great job of clearing debris to keep things cool, though you still need to manage your speed and pressure when working through tougher metals to get the most out of the durability.
