Value Collection SM26N09 Taper Pin Reamer No. 9

Product Description

The VALUE COLLECTION SM26N09 is a No. 9 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Manufactured from high-speed steel with a bright, uncoated finish, this reamer delivers consistent material removal across a range of ferrous and non-ferrous workpieces. The tool features a helical flute configuration with a right-hand cutting direction and a left-hand spiral, producing a smooth finish while reducing chatter. With a small end diameter of 0.4805 inches and a large end diameter of 0.6066 inches, it conforms to the No. 9 taper pin standard at a taper rate of 1:48. Machinists and tool and die professionals rely on this reamer for general-purpose production and maintenance work.

This reamer is suited for machine shop, maintenance, and repair applications where precision tapered holes are required. It is used in situations where a standard drill cannot produce the final taper geometry needed for a press-fit or pinned joint. The straight shank measures 0.5625 inches (9/16 inches) in diameter, making it compatible with standard drill chucks and collet holders. It is well-suited to manual drill presses, milling machines, and hand-held operations where controlled feed rate and proper alignment are maintained throughout the cut.

Compatibility

Designed as a general-purpose No. 9 taper pin reamer suitable for use in drill presses, milling machines, and similar machine tool setups that accept a straight-shank tool at 0.5625 inches shank diameter.

Installation Notes

This tool should be installed and operated by a qualified machinist or tooling professional. Secure the straight shank firmly in a drill chuck or collet before use, and verify runout before beginning the cut. Apply an appropriate cutting fluid throughout the operation to extend tool life and improve surface finish. Feed the reamer gradually and never force the tool, as excessive feed pressure can cause tool deflection or an oversized taper.
