Features:

• 50x more holes and 2x faster than titanium or black oxide coated step drill bits
• Super-hard Mach-Blueâ„¢ Armor Plating retains sharper cutting edges, and reduces heat build-up and cutting friction
• Durable drill bit for long drill life, precision holes, and increased speed and productivity in tough to drill applications
• Impact rated 1/4-in speed hex won’t slip in conventional 3-jaw chucks and is ideal for use in quick change impacting power tools
• Optimized 135-degree 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 stainless steel, mild steel, aluminum, stacked materials and other difficult to drill alloys
