Indexable 4-1 Counter Bore
Indexable 4-1 Counter Bore

4-in-1 counter bore patented by YIH TROUN reduces 5 machining processes into two processes.

Traditional machining of counter bore holes needs preparation of several cutting tools. It leads to longer machining time and tool cost. Tool replacement time alone occupies over 1/3 of total machining time.

Traditional machining needs at least 5 steps

Counter Bore-Center standard processing flow

The innovative solution of YIH TROUN combines all of spot drill + counter bore + upper hole chamfering + lower hole chamfering into the same carbide insert design. It needs only 2 steps and 3 seconds to finish the machining. It saves a lot of machining time and improve your delivery competitiveness.
