Sandvik Coromant 860.1-0480-014A1-MM2214 CoroDrill 860 Solid Carbide Drill

High performance drills optimized for steel, stainless steel and aluminium CoroDrill 860 is a solid carbide drill designed for a fast and problem-free drilling. It maximizes productivity through high metal cutting efficiency and machine utilization. With excellent chip evacuation in long and short chipping materials, CoroDrill 860 provides green light machining at high penetration rates. The CoroDrill 860 product offer consists of three drill geometries – optimized for steel, stainless steel and aluminium. The drill comes in lengths 3 – 8×D as standard. Benefits Optimized cutting data Low cost per hole Improved performance reliability Trouble-free chip evacuation Long tool life, controlled wear formation Consistent hole tolerance Features Unique cutting edge shape lowers cutting forces and improves chip control Flute shape optimizes chip form to improve chip flow and evacuation Tough carbide extends tool life Edge preparation controls wear and provides greater reliability Reinforced drill corner adds strength and process security Can be reconditioned up to3 times to its original specification Application 860-PM ; Long- and short-chipping steel materials, such as unalloyed steels, low carbon steels, low-alloy steels, high-alloy steels and steel castings 860-NM ; Non-ferrous materials, such as aluminium alloys, magnesium and copper based alloys including bronze 860-MM ; Long-chipping stainless steel materials such as austenitic, super austenitic, ferritic and duplex stainless steels Standard diameter range ; -PM and -NM ; 3–20 mm (0.118−0.787 inch) -MM ; 3–16 mm (0.118–0.629 inch)Drill lengths ; 3–8 × drill diameter Achievable hole tolerance ; -PM and -NM ; H8–H9 -MM ; H6–H8 Conventional drilling Chamfered holes Inclined surfaces Cross holes Stack drills Convex or concave surfaces
