Value Collection SM25N13 Taper Pin Reamer No. 13 Hss

Product Description

The VALUE COLLECTION SM25N13 is a No. 13 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 and a right-hand cutting direction. The small end diameter measures 1.009 inches and the large end measures 1.259 inches, with a taper rate of 1:48. The 12-inch flute length and 16-inch overall length make it suited for deep-reach applications in heavy fabrication and machine shop environments. A licensed machinist or tool and die professional typically performs this work.

This reamer is used when a tapered hole must be precisely sized to receive a standard taper pin for shaft-to-hub or component-to-component locking applications. It is appropriate for general-purpose use in metalworking, maintenance, and fabrication settings. The straight shank measures 1.25 inches in diameter, making it compatible with standard large-bore drill presses, milling machine spindles, and manual boring setups where a matching chuck or collet is available. The spiral flute promotes smooth chip evacuation during cutting.

• Straight shank at 1.25 inches diameter fits standard large-bore chucks and collets

Compatibility

Designed for use with standard No. 13 taper pin applications requiring a 1:48 taper rate in metalworking, fabrication, and maintenance operations.

Installation Notes

This reamer is installed and operated by machinists or tooling professionals using a drill press, milling machine, or manual boring setup. Always secure the workpiece fully before reaming and apply an appropriate cutting fluid to extend tool life and improve finish quality. Do not force the reamer through the bore; feed at a controlled rate to avoid chatter or tool deflection. Follow applicable shop safety procedures when handling high-speed steel cutting tools.
