- Heavy duty bits for drilling hard tough metals: free machining stainless steel, high temperature alloys, titanium and certain plastics
- High red hardness allows 30% higher drilling speeds over regular high speed steel drill bits
- Feature razor sharp 135° split point self centring tips, eliminating "walking" and the need for centre punching.
- The superior bronze oxide (gold) ground flute finish reduces friction, translating to less operator pressure, and longer life
- Special flute form enhances chip ejection, reduces drill retractions (woodpeckering) and improves coolant flow to the tip
- For best results use in rigidly held positive feed drilling equipment
- Size : 5/16"
