IRWIN Cobalt Steel Drill Bit is ideal for drilling into hardened steel, alloys, titanium and stainless steel
- Constructed of M-35 5 percent cobalt high speed steel for super abrasive resistance in tough metals
- Heavy duty spiral flute design produces faster chip ejection
- 5% cobalt for higher heat and abrasion resistance
- Best heat resistance for drilling in extremely hard and abrasive materials including stainless steel, titanium and cast iron
- 135 degree split point begins drilling immediately, minimizing bit walk
