SureWerx (545) 573421 JET 21/64" JET-KUT® COBALT Super Premium Cobalt Jobber Drill Bit

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
