Description

• 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
