SPYDER 19024 Mach-Blue 1/4″ – 1-3/8″ 10-Step Bit

• Up to 50x more holes than titanium or black oxide drill bits
• Up to 2x faster than titanium or black oxide drill bits
• Proprietary Mach-Blue™ Armor Plating is a super hard surface plating 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 135° 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 sheet materials and other tough-to-drill alloys
• Made in the USA
