FOREWORD
This Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards, after the draft finalized bytbc Drills, Reamers and Threading Tools Sectional Committee had been approved by the Basic and ProductionEngineering Division Council.
This standard was first published in 1963 and subsequently revised in 1973 to bring it in line with ISO/R 296. Thesecond reyision was taken up in 1986 to align it with ISO 296: 1974 ‘Machine tools — Self- holding tapers for toolshanks’ 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 it with the latest version of its base standards thatisISO296:1991 andDIN 228 (Teil 1 & Teil 2): 1987. The title of the standard has been modified. This revision also includes thefollowing 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) In Table 1,1, dimensions for-MT3, MT6 and metric Papers 80 to 200 have been modified.c) In Table 3, dimensions Zhas been modified.d) In Annex A, the word ‘recommended’ has been included in the title and a clause 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 forStandardization (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 ftir Normung(DIN)

SELF-HOLDING TAPERS — DIMENSIONS(Third Revision)
1 SCOPE
1.1 This standard specifies the dimensions of Self-Holding Tapers with a small taper of about 4 to 5 percentclassified, according to their use, into the three followingcategories:
a) Tapers for general use No. 1 to 6 morse tapersb) Smaller tapers No. 4 and 6 metric and
No. Omorsec) Larger tapers No. 80 to 200 metric
1.2 This Indian Standard also specifies the dimensionof grooves and holes necessary for the design of tapersfor applications where coolant supply is required.
1.3 Recommended method of measuring tolerance ontapers is given in Annex A.
