DIN Standards Committee Tools and Clamping Devices

Overview

This standard specifies the dimensions for hardmetal machine reamers with parallel shank for use as NC-reamers for both conventional chucks as well as for expansion clamping chucks according to DIN 69882-7 and shrink chucks as in DIN 69882-8. The standard has been divided into Parts 1 and 2 and, in addition, the titles of the standard have been correspondingly adapted. The scope of Part 2 has been adapted and the normative references have been updated in relation to the requirements for NC-reamers according to this standard. Furthermore, the example for the designation of NC-reamers has been adapted. The specifications for materials have also been updated for the revised Part 2. This standard has been prepared by Working Committee NA 121-01-03 AA "Senker, Aufbohrer und Reibahlen aus Schnellarbeitsstahl und Schneiden aus Hartmetall" ("Countersinks, core drills and reamers of high-speed steel and hard metal tips") at the Tools and Clamping devices Standards Committee (FWS) at DIN, the German Institute for Standardization e. V.
