Value Collection SM26N08 Taper Pin Reamer Size 8 Hss

Product Description

The VALUE COLLECTION SM26N08 is a Size 8 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to precise dimensional tolerances. Constructed from high-speed steel with a bright, uncoated finish, this reamer delivers reliable cutting performance in general-purpose machining applications. The tool features a small end diameter of 0.3971 inches and a large end diameter of 0.505 inches, with a 1:48 taper rate that conforms to standard taper pin geometry. A helical flute design and right-hand cutting direction support controlled chip evacuation during the reaming pass. Machinists and tool-and-die professionals use this reamer when fitting and driving standard taper pins in mechanical assemblies.

This taper pin reamer is suited for use in machine shops, maintenance and repair operations, and production environments where standard Size 8 taper pin holes are required. The straight shank accepts standard drill chucks and collet holders. With a 5.1875-inch flute length and 7.1875-inch overall length, it provides adequate reach for most typical workpiece thicknesses encountered in general mechanical fabrication and assembly work.

Compatibility

Designed as an OEM-style replacement and general-purpose tool for Size 8 taper pin reaming operations in standard machine shop and maintenance applications.

Installation Notes

This reamer is installed and operated by machinists using a drill press, milling machine, or compatible hand-held drilling equipment fitted with a suitable chuck or collet. Secure the workpiece firmly before reaming to prevent movement. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Do not force the reamer through material at excessive feed rates, as this can damage the cutting edges or produce an out-of-tolerance hole.
