103305 PREMUS, 3 × A11, TiAlN

Drill reamer PREMUS, 3 × A11, TiAlN

High-performance drill reamer: drilling and reaming in one operation.

Design:

- with 2 drilling cutting edges and 4 reaming cutting edges

- specific grinding

- point angle 140°

- side rake angle 30°

- solid carbide micrograin 10-12% Co

- TiAlN-coated

- with twisted cooling channels

Use:

drilling and reaming in one operation without any loss of reaming quality. The two drilling cutting edges initially process the solid material, the four reaming cutting edges then carry out the finishing. Very good surface quality. Optimum roundness, maximum alignment accuracy and coaxiality. For blind and through holes. Suitable for example for positioning holes in cylinder heads, crankshafts or gearbox housings. Can be precisely regrinded.
