Spyder Stinger™ Mach-Blue™ Armor Plated 11/64" 4.4mm

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.

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
Advanced M-Series alloy tool steel construction and proprietary heat treatment increase drill bit durability, rigidity and breakage resistance
Ideal for drilling wood with nails, stainless steel, mild steel, aluminum, stacked materials and other tough to drill alloys
