Sandvik introduces exchangeable-head CoroMill 316 with coolant holes
Sandvik Coromant's exchangeable-head CoroMill 316, which is suitable for high feed face milling, slot milling, helical interpolation, shoulder milling, profile milling and chamfer milling in material groups ISO P to ISO S, will shortly be available with internal coolant holes.
The machining of such materials as heat resistant super alloys, titanium and stainless steels often requires the use of coolant for temperature control and chip evacuation during cutting. Re-cutting of chips and chip jamming often lead to poor surface quality, damage to the cutting edge and tool breakage. Precise positioning of coolant holes in CoroMill 316 optimises the effect of the coolant jet to overcome these problems.
The exchangeable head system allows machine shops to quickly and accurately switch between cutter type, radius variation, teeth frequency, geometry and grade. Sandvik Coromant says that CoroMill 316 end mills are even suitable for 5-axis milling of flanks which often require tapered tools for stability at longer tool reach.
