FOREWORD This Indian Standard (Third Revision) was adopted bythe Bureau ofIndian Standards, after the draft finalized by tbc Drills, Reamers and Threading Tools Sectional Committee had been approved by the Basic and Production Engineering Division Council. This standard was first published in 1963 and subsequently revised in 1973tobring itinline with ISO/R 296. The second reyision was taken up in 1986toalign itwith ISO 296: 1974 ‘Machine tools — Self- holding tapers fortool shanks’ and DIN 228 (Teil 1&Teil 2):1982’ Morse tapers and metric tapers, taper shanks and taper sockets’. This revision was again taken up to align itwith the latest version ofitsbase standards thatisISO296:1991 and DIN 228 (Teil 1& Teil 2):1987. The title of the standard has been modified. This revision also includes the following modifications: a) New types of shanks and sockets listed below have been included: 1) External self-holding taper for tool shanks with tapped hole and coolant supply, Type AK. 2) External self-holding tapers for tool shanks with tanged end and coolant supply, Type BK. 3) Internal self-holding tapers for sockets with tapped hole and coolant supply, Type CK. 4) Internal self-holding tapers for sockets with tanged end and coolant supply, Type DK. b) InTable 1,1,dimensions for-MT3, MT6 and metric Papers80to200 have been modified. c) InTable 3,dimensions Zhas been modified. d) In Annex A, the word ‘recommended’ has been included inthe title and aclause A-3 added. In the preparation of this standard, considerable assistance has been derived from the following: ISO 296:1991 Machine tools — Self-holding tapers for tool shanks issued by International Organization for Standardization (1S0) DIN 228 Teil 1:1987 Morse tapers and metric tapers, taper shanks issued by Deutsches Institute fur Normung (DIN) DIN 228 Teil 2:1987 Morse tapers and metric tapers, taper sockets issued by Deutsches Institut ftirNormung (DIN) Is 1715:2002 Indian Standard SELF-HOLDING TAPERS — DIMENSIONS (Third Revision) 1 SCOPE 3 DIMENSIONS 1.1 This standard specifies the dimensions of Self- 3.1 ExtemalSelf-HoklingTapers forToolShanks with Holding Tapers with asmall taper ofabout 4to5 percent Tapped Hole orPlainen@TypeA-As giveninTable 1. classified, according totheir use, intothethree following 3.2 ExternalSelf-Holding Tapers forToolShanks with categories: Tanged End, Type B— Asgiven inTable 2. a) Tapers forgeneral use No. 1to 6morse tapers b) Smaller tapers No. 4 and 6 metric and 3.3 External Self-Holding Tapers for Tool Shanks No. Omorse withTapped HoleandCoolant Supply, TypeAK— As c) Larger tapers No. 80to200 metric given inTable 1. 1.2 This Indian Standard also specifies the dimension 3.4 External Self-HoldingTapers forToolShanks with ofgrooves and holes necessary for the design oftapers Tanged EndandCoolant Sup@y,Type BK—As given for applications where coolant supply isrequired. inTable 2. 1.3 Recommended method ofmeasuring tolerance on 3.5 IntemalSelf-HoldingTape~ forSocketswith Tapped tapers isgiven inAnnex A.
