Hand reamer, adjustable Design: Right cutting, with replaceable blades made of HSS, factory standard and cylinder shank with square drive. The uneven blade pitch ensure chatter-free and accurate drilling. The reamer can be progressively set within the stated adjustment range. The setting should be made using a ring gauge. Bright surface Application: Particularly suitable for repair work. Only for reaming through holes. Not suitable for machining blind holes due to the head screw. 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.
