Spyder Stinger Mach-Blue high speed steel (HSS) drill bits are high-performance metal and wood drilling bits that provide exceptional quality, durability, drilling performance, and value. The Mach-Blue surface treatment and advanced M-series alloy tool steel construction retain sharper cutting edges and reduce heat build-up for increased durability, rigidity, and breakage resistance. Spyder Mach-Blue impact-rated driver bits are durable driving bits for demanding high-torque impacting applications. Mach-Blue Tough Tip Technology significantly reduces tip wear for reliable fastener driving. IMPACTive alloy tool steel torsion zones actively flex to dissipate peak impact forces, reducing fastener recess damage and preventing tip breakage. Spyder Mach-Blue Drill and Driver Bits are the pro powered tools that outlast your workday.

Features / Benefits
