Specifications
The Irwin Tools 30528 7/16-Inch Cobalt Alloy Steel 135-Degree - Left Handed-Mechanics Length is made of M42 Cobalt Alloy Steel. The Cobalt Alloy Steel helps discipate heat, which is the killer of all drill bits, providing it with longer life and more durability. The Cobalt Alloy Steel construction allows this bit to drill abrasive materials like Stainless Steel and Cast Iron which are extremely tough on traditional high speed steel drill bits. The bit has a 135-degree split point tip to help eliminate walking as you start to drill the hole in metal. The straight shank works in both keyed and key-less chucks. The left handed cutting direction makes this bit ideal for drilling into broken fasteners to extract them. The left handed direction keeps the fastener from being driven in any further and sometimes the drill direction can extract the broken fastener without need an extractor.
- Constructed of M-42 8 percent cobalt alloy high speed steel for super abrasive resistance in tough metals
- Heavy duty spiral flute design produces faster chip ejection
- Shorter cutting lips reduce torque for drilling in high tensile strength materials.
- 135-degree split point reduces feed pressure for easier penetration without work hardening
- Ideal for use with screw extractors

- MADE FOR DURABILITY: M-42 8% Cobalt Alloy Steel for higher heat and abrasion resistance
- BUILT FOR POWER: Heavy-duty spiral flute for fast chip ejection and shorter drill for added strength
- SUPERIOR PERFORMANCE: 135° split-point tip prevents walking
- SMART DESIGN: Left-handed cutting direction drills into broken fasteners to extract them
This IRWIN Left-Hand Cobalt Alloy Steel HSS Fractional Mechanics-Length Drill Bit is made from 8% Cobalt Alloy Steel-alloyed steel for higher heat- and abrasion-resistance. A shorter length provides additional strength. The drill bit is useful for drilling into fasteners without tightening them and can often remove broken fasteners without the use of an extractor.
