Hand reamer Design: HSS, DIN 206-B, with approx. 7° left spirals and long, conical point (approx. 1/3 of cutting length). The uneven tooth pitch ensure chatter-free and accurate drilling. With cylinder shank with square drive. Bright surface Application: Perfectly suited for single production or repair work, only for reaming through holes. Not suitable for machining blind holes due to the long, conical point geometry. Also suitable for holes with interrupted cut. Particularly suitable for steel materials up to 500 N/mm² in strength e.g. general construction steels, steel materials up to 900 N/mm² in strength such as machine steels, tempered steels, tool steels, case-hardening steels, casting materials and non-ferrous metals such as aluminium, brass, copper and bronzes. Further dimensions or straight fluted available on request.
