PCD drilling reamer cutter

With rough finish maching of front cover valve hole,
PCD point designed by cutting edge,can effectively
deal with the cast problelm ,for example,workblank
allowance is uneven in the rough machining and the
bottom of the hole is solid ,that will make the cutting
tool cut better.Extrusion cutting design of PCD cutting
edge makes the processed surface obtain higher
Roughness and brightness. It can leave out finish
machining procedure, greatly improving efficiency of
producing and stability of size.
