Value Collection SM25N02 Taper Pin Reamer Size 2 Hss

Product Description

The VALUE COLLECTION SM25N02 is a size 2 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer features a spiral flute with left-hand spiral direction and right-hand cutting action. The small end diameter measures 0.1605 inches and the large end measures 0.2006 inches, providing the correct taper for a size 2 pin fit. Overall length is 3.1875 inches with a flute length of 1.9375 inches. Licensed machinists, toolmakers, and maintenance technicians use this tool in drill press and hand-turning applications.

This taper pin reamer is suited for general-purpose metalworking operations where a standard size 2 tapered hole is required. Typical applications include pinning shafts to hubs, securing mechanical assemblies, and preparing holes for taper pin fasteners in both production and maintenance environments. The straight shank at 0.2031 inches (13/64 inches) fits standard drill chucks and collet holders, making it compatible with common machine tool setups in job shops, maintenance facilities, and manufacturing operations.

Installation Notes

This reamer is installed and operated by machinists or maintenance technicians using a drill press, milling machine, or hand brace. Always secure the workpiece firmly before reaming and use cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Begin with a drilled hole close to the small end diameter and ream progressively to achieve the final taper fit. Never force the reamer; excessive pressure can cause tool deflection or breakage.
