BS ISO 03365:2016 pdf download – Indexable hardmetal (carbide) inserts with wiper edges, without fixing hole — Dimensions 3 Types of inserts The types of indexable hardmetal (carbide) inserts specified in this International Standard are the following: — TP … PPN symmetrical triangular inserts with 11° normal clearance, 90° cutting edge angle, and 11° wiper edge normal clearance; — TP … PDR; TP … PDL asymmetrical triangular inserts with chamfered corners, 11° normal clearance, 90° cutting edge angle, and 15° wiper edge normal clearance; — TE … PER; TE … PEL asymmetrical triangular inserts with chamfered corners, 20° normal clearance, 90° cutting edge angle, and 20° wiper edge normal clearance; — SN … ENN symmetrical square insert with chamfered corners, 0° normal clearance, 75° cutting edge angle,and 0° wiper edge normal clearance; — SP … EDR; SP … EDL asymmetrical square insert with chamfered corners, 11° normal clearance, 75° cutting edge angle,and 15° wiper edge normal clearance; — SN … ANN symmetrical square insert with 0° normal clearance, 45° cutting edge angle, and 0° wiper edge normal clearance; — SE…. EER; SE…. EEL asymmetrical square insert with 20° normal clearance, 75° cutting edge angle, and 20° wiper edge normal clearance. Inserts with wiper edges, without fixing hole, are standardized only without chip breakers. 4 Interchangeability 4.1 Tolerances Indexable hardmetal (carbide) inserts specified in this International Standard are provided in the following tolerance classes in accordance with ISO 1832: a) inserts with 0° and 11° normal clearance (TP, SN, and SP) tolerance classes A, C, and K, where class C is used mainly for coated inserts; b) inserts with 20° normal clearance (TE and SE) tolerance class C. The values of the tolerances in accordance with ISO 1832 are given in Annex A. Other tolerances are included in the diagrams and tables with the insert dimensions in Clause 7. 4.2 Dimensions m Dimension m specified in the tables refers to a theoretically perfect insert. In practice, as the points on which the inserts are located in both manufacturing and measuring may be different, the nominal value of dimension m may vary from one manufacturer to another within a range of ± 0,05 mm. Nevertheless,for inserts of the same manufacturer, dimension m shall comply with the tolerances in accordance with ISO 1832 (see Annex A). 5 Designation and marking 5.1 Designation The designation of the indexable hardmetal (carbide) inserts complying with this...
