BS 328-4:1983

This standard BS 328-4:1983 Drills and reamers is classified in these ICS categories:

• 25.100.30 Drills, countersinks, reamers

This Part of this British Standard specifies the dimensions of the following commonly used types of reamer:

hand reamers

long-flute machine reamers¹⁾ with Morse taper shanks

machine chucking reamers¹⁾ shell reamers

socket reamers

hand taper pin reamers

machine taper pin reamers

bridge reamers

A method of calculating tolerances for special reamers is given in Appendix A. Appendix B shows the values of certain of the limits of tolerance specified, extracted from BS 4500-1. Appendix C specifies preferred inch sizes of cutting diameters for various types of reamer, and Appendix D shows tables of dimensions set out as functions of reamer diameter, i.e. “general tables”.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
