Value Collection ATR2581 Taper Pin Reamer No 7/0 Hss

Product Description

The VALUE COLLECTION ATR2581 is a No. 7/0 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Constructed from high speed steel with a bright, uncoated finish, this reamer features a spiral flute geometry with right-hand cutting action and left-hand spiral direction. The small end diameter is 0.0497 inches and the large end diameter is 0.0666 inches, conforming to the 1:48 taper rate standard for taper pin applications. Machinists, tool-and-die technicians, and general machine shop personnel use this tool for precision hole preparation in metalworking operations.

This reamer is suited for general-purpose metalworking where a No. 7/0 taper pin fit is required. Typical applications include fitting taper pins in shafts, collars, levers, and mechanical assemblies where a secure, removable locating pin connection is needed. The compact overall length of 1.8125 inches and 5/64-inch straight shank make it compatible with standard drill press chucks and hand-held pin vise holders used in bench-level precision work. It is appropriate for use in both production and maintenance environments.

Compatibility

Designed as an OEM-style replacement and general-purpose tool for machines and assemblies requiring a No. 7/0 standard taper pin hole, with a straight shank that fits standard drill chucks and pin vise holders accepting a 0.0781-inch shank diameter.

Installation Notes

This tool is installed and operated by machinists or skilled technicians using a drill press, tapping fixture, or hand-held pin vise. Secure the workpiece firmly before reaming to prevent movement and maintain hole alignment. Apply a suitable cutting fluid to extend tool life and improve surface finish. Do not force the reamer through material; feed with light, consistent pressure to avoid tool deflection or breakage on this small-diameter tool.
