Spyder Stinger Mach-Blue 10-Piece Assorted High-speed Steel Jobber Length Twist Drill Bit Set

The Spyder Stinger Mach-Blue Armor Plated high speed steel (HSS) bits are high performance metal and wood drilling bits that provide exceptional drill bit quality and durability, drilling performance, and value. The Mach-Blue armor plating combined with the advanced M-series alloy tool steel construction and proprietary heat treatment make these bits truly revolutionary - they retain sharper cutting edges for longer, have reduced heat build-up and cutting friction, and increased durability, rigidity, and breakage resistance. These incredibly durable bits are the Pro's choice for precision drilling, extended bit life, and value.
