Value Collection SM26N13 Taper Pin Reamer No. 13 Hss

Product Description

The VALUE COLLECTION SM26N13 is a No. 13 taper pin reamer designed for precision hole enlarging, finishing, and shaping in metalworking and mechanical assembly applications. Manufactured from high-speed steel with a bright, uncoated finish, this reamer features helical flutes and a right-hand cutting direction for smooth, controlled material removal. The tool measures 16 inches overall length with a 12-inch flute length and a 1.25-inch straight shank. The small end diameter is 1.009 inches and the large end diameter is 1.259 inches, conforming to a standard 1:48 taper rate.

This reamer is suited for general-purpose taper pin hole preparation in manufacturing, maintenance, and repair environments. It is used by machinists, millwrights, and tool-and-die professionals working on shafts, hubs, and mechanical assemblies where taper pin fits must be precisely reamed to size. The helical flute geometry reduces chatter and produces a cleaner finish than straight-flute designs, making it a reliable choice for production and job-shop work alike.

Key Features

• No. 13 taper pin size with 1:48 taper rate for standard taper pin fitment
• High-speed steel construction for durability across a range of workpiece materials
• Helical flute geometry reduces chatter and improves surface finish
• Right-hand cut with left-hand spiral for controlled chip evacuation
• Bright, uncoated finish suitable for general-purpose applications
• 1.25-inch straight shank compatible with standard milling machine and drill press chucks

Compatibility

Designed as a general-purpose taper pin reamer for use in standard machine shop equipment including milling machines, drill presses, and reaming fixtures that accept a 1.25-inch straight shank.

Installation Notes

This tool should be installed and operated by qualified machinists or skilled tradespeople. Secure the shank firmly in the machine chuck before operation and verify spindle runout is within acceptable tolerances to avoid taper deviation. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Never force the reamer through a hole that is significantly undersized; always pre-drill or bore close to the finished taper dimensions before reaming.
