Spyder 7/16" Quick Change Drill Bit with Hex Shank, for Wood, Metal, Plastic, PVC (19015)

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.

• Up to 100x more holes than titanium or black oxide drill bits
• Up to 8x faster than titanium or black oxide drill bits
• Proprietary Mach-Blue Armor Plating is a super hard surface that retains sharper cutting edges, and reduces heat build-up and cutting friction — resulting in faster cuts and exceptionally long drill life
• Impact-rated 1/4″ speed hex won’t slip in conventional 3-jaw chucks and ideal for use in quick change impacting power tools
• Optimized 137° self-centering split point cutting geometry won’t walk or wander — even on pre-hardened or curved surfaces
