Irwin® 30516 Left-Hand Mechanics Length Cobalt High Speed Steel Drill Bit, 1/4 In, Split

The Irwin 30516 Left-Hand Mechanics Length Cobalt Drill Bit is a specialized tool engineered to remove broken fasteners and drill into high-tensile materials. Its counter-clockwise rotation allows it to back out snapped bolts and screws during the drilling process, often eliminating the need for separate extraction tools.

• Manufactured from M-42 8% cobalt high-speed steel for exceptional heat and abrasion resistance when drilling hardened steel.
• The 135-degree split point design prevents the bit from walking and reduces required feed pressure for easier penetration.
• Shorter mechanics length provides increased rigidity and strength to withstand high torque in demanding industrial applications.

This drill bit is ideal for maintenance professionals, mechanics, and industrial technicians who regularly deal with broken studs, hardened bolts, and high-strength metal alloys.
