Multi-Function Cutter Prevents Chipping in Spot Drilling

Big Kaiser has introduced two versions of the C-Centering Cutter, a multi-function cutter capable of spot drilling, centering and chamfering. It is an indexable cutter that uses a specialized insert that can start a hole from a solid piece. It can also perform spot drilling and 90-degree chamfering at the same time, or it can be used strictly for hole chamfering.
During spot drilling, the insert-nose radius can be easily chipped with general cutters since the center has a peripheral speed of zero. But the coolant hole in the C-Centering Cutter enables cooling of the cutting edge, which reaches high temperatures during spot drilling and enables immediate chip evacuation. This prevents chipping during spot drilling.
The latest version of the C-Centering Cutter is a three-insert cutter, which is only used for chamfering. This version is perfect for general chamfering and results in a reduction of cycle time over using the single-insert version.
