Up to 100x more holes and 8x faster than titanium or black oxide coated drill bits. Super-hard Mach-Blue™ 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 137-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, wood, stacked materials and other difficult to drill alloys. Made in the USA with domestically and globally sourced materials.
