Ingersoll Flat Bottom Hole Machining

Ingersoll has extended the application range of the successful drilling line by introducing a flat-face geometry tip for flat bottom machining, in a diameter range of 8.00mm to 25.5mm (.312″ – 1.012″).

The new line reduces the number of tools required to generate a flat bottom hole from 2 or 3 tools to a single tool, greatly reducing cycle time. The new geometry is compatible with the ’s current line of bodies in the same size. Further benefits are excellent chip breaking and high precision flat surfaces.

FEATURES:
