Sandvik Coromant's 316 exchangeable-head milling system with internal coolant holes.

The CoroMill 316 system is suitable for high feed face milling, slot milling, helical interpolation, shoulder milling, profile milling and chamfer milling of components in material groups from ISO P to ISO S.

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. By offering an internal coolant solution, CoroMill 316 is able to outperform existing solutions with external coolant, Sandvik Coromant claims.

The CoroMill 316 system allows machine shops to switch between various operations such as cutter type, radius variation, teeth frequency, geometry and grade. The end mills are also suitable for five axis milling of flanks which often require tapered tools for stability at longer tool reach.
