Carbide stop hole reamer

●All cemented carbide · ultrafine particles

●For blind holes, for through holes, for stepped use

※TiCN coding also has various stocks

Surface accuracy is good. Our unique two-stage cutting method (rough blade, finishing blade)

It is straightforward. It is made short overall and excellent in rigidity.

Stepped processing is also possible, with bottom blade.

・Please carry out chamfering work of pilot hole as preprocessing.

・Please pay attention to reel core runout, misalignment.

・Please use oil cutting oil for cutting oil.
