[Superseding IS 11943 (Part 12) : 1987]

NATIONAL FOREWORD

This Indian Standard (Part 12) which is identical to ISO 7755-12 : 2013 'Hardmetal burrs - Part 12: Inverted cone burrs (style N)' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Cutting Tools Sectional Committee and after approval of the Production and General Engineering Division Council.

Hard metal burrs are cutting tools used in various machining and metalworking applications. Their functions encompass material removal, deburring of sharp edges, crafting intricate profiles, and providing the finishing touches to workpieces. These burrs are available in diverse shapes and sizes including cylindrical, spherical, conical varieties and each shape is uniquely tailored for specific cutting, shaping and grinding tasks.

This standard supersedes IS 11943 (Part 12) : 1987 'Specification for hard metal burrs: Part 12 Inverted cone burrs (type N)'.

This standard is published in twelve parts. Other parts in this series are:

Part 1 General specifications

Part 2 Cylindrical burrs (style A)

Part 3 Cylindrical round- (ball-) nose burrs (style C)

Part 4 Spherical burrs (style D)

Part 5 Oval burrs (style E)

Part 6 Arch round- (ball-) nose burrs (style F)

Part 7 Arch pointed-nose burrs (style G)

Part 8 Flame burrs (style H)

Part 9 60 degrees and 90 degrees cone burrs (styles J and K)

Part 10 Conical round- (ball-) nose burrs (style L)

Part 11 Conical pointed-nose burrs (style M)

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
