For Cylinder Head Cutting PCD Rotating Tools
Automotive Components
Features A single reamer can finish multi-stage holes, reducing work processes. Delivering an excellent surface finish unobtainable with carbide tools. Precise and stable dimensional and shape accuracy unique to diamond tools can be maintained for a long time. Cutting speed and feed can be tuned to reduce machining time. D D D D

High-precision / high-efficiency machining is realised through high-quality cutting edge accuracy created by diamond precision machining technology. Data 2: Good Balance between High-efficiency Cutting and High Machining Accuracy
Data 1: Improved Productivity due to Breaking Chips
Negative Land Specification Cutting Edge
Shim Fitting Hole
The chipbreaker function has been enhanced to prevent a reduction in productivity due to problems caused by chips. Solutions are proposed according to the type of chip problem.
