Description

Machine reamer Design: HSS-E, with approx. 7° left spirals, short point and uneven tooth pitch. This achieves clean and exact drilling. With cylinder shank. Tolerance h9. Application: For reaming through holes, also conditionally suitable for reaming blind holes due to the short trim cut. Especially for steel materials such as general structural steels, machining steels, tempered steels, case hardened steels, tool steels, high-speed steels, cast iron, spheroidal graphite and malleable cast iron, which can be used in non-ferrous metals such as aluminium and brass.
