The Irwin M-35 cobalt drill bit delivers reliable performance in hardened steel, stainless steel, titanium, and other tough metals. The 5% cobalt alloy provides superior heat and abrasion resistance compared to standard high-speed steel bits, letting you cut faster and last longer in demanding applications.

• M-35 cobalt alloy steel (5% cobalt) for maximum hardness and heat resistance
• 135-degree split point starts on contact and reduces walking
• Heavy-duty web construction for added strength
• Gold oxide finish for corrosion resistance
• Straight shank jobber length design
• Drills hardened steel, stainless steel, titanium, and super alloys
• Size: 11/32" diameter x 4-3/4" overall length
• Sold individually on a card

Tip: Run at slow, steady speed with cutting oil when drilling hard metals to maximize bit life and prevent overheating. Let the bit do the work -- excessive pressure causes premature wear.
