IRWIN Cobalt M35 Jobber Drill Bits 135-Degree Split Point

These IRWIN cobalt jobber drill bits are constructed from cobalt alloy steel (M35) or cobalt-enhanced high-speed steel to improve heat dissipation and durability when drilling abrasive metals. A 135-degree split point tip reduces walking for accurate hole starts, and heavy-duty spiral flutes help eject chips quickly for efficient drilling. Most variants feature a straight shank compatible with keyed and keyless chucks; some listings include reduced shank geometry. Recommended for stainless steel, cast iron and other tough metalworking tasks, these bits are suited to maintenance, industrial and professional applications.

• Shorter cutting lips reduce torque for drilling in high tensile strength materials
• Heavy duty spiral flute design produces faster chip ejection
• Straight shank works in both keyed and key-less drill chucks
• Jobber drill bits feature 135-Degree Split Point Tips for reduced bit walking
• M-35 Cobalt Construction for Durability in abrasive materials
