10-Piece Assorted Mach-Blue Coated HSS Twist Drill Bit Set SPYDER Popular

Description

The Spyder Stinger Mach-Blue Armor plated HSS (high speed steel) 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. Impact rated 0.25 inch speed hex will not slip in conventional 3-jaw chucks and is ideal for use in quick change impacting power tools. Optimized 137 degrees self-centering split point cutting geometry will not walk or wander – even on pre-hardened or curved surfaces. They retain sharper cutting edges for longer, have reduced heat build-up and cutting friction, and increased durability, rigidity, and breakage resistance. Ideal for drilling stainless steel, mild steel, aluminum, wood, stacked materials and other difficult to drill alloys, these incredibly durable bits are the Pro’s choice for precision drilling, extended bit life, and value. They procure 100X more holes and are 8 times faster than titanium or black oxide coated drill bits.
