Value Collection SM26N05 Taper Pin Reamer No 5 Hss

Product Description

The VALUE COLLECTION SM26N05 is a No. 5 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard No. 5 taper pins. Manufactured from high-speed steel (HSS), this reamer features a helical flute geometry and a bright, uncoated finish suited for general-purpose machining work. The small end diameter is 0.2409 inches and the large end diameter is 0.2994 inches, following a 1:48 taper rate. The tool has an overall length of 4.3125 inches and a flute length of 2.8125 inches. It is installed by machinists, tool-and-die workers, and maintenance technicians working on precision assemblies.

This taper pin reamer is used in both production and maintenance environments where tapered-hole accuracy is required. Typical applications include fitting taper pins into shafts, hubs, and mechanical assemblies across general manufacturing, repair shops, and machine tool maintenance. The right-hand cutting direction and helical flute pattern make it appropriate for use in a drill press, milling machine, or hand-held brace at controlled feed rates. It is suited for ferrous and non-ferrous materials under general-purpose cutting conditions.

Key Features

• No. 5 taper pin size with a 1:48 taper rate for accurate pin-hole fitment
• High-speed steel construction for durability across general-purpose materials
• Helical flute design promotes smooth chip evacuation during cutting
• Bright, uncoated finish maintains consistent dimensional accuracy out of the box
• Right-hand cut with left-hand spiral for reduced chatter and improved surface finish
• Straight shank at 0.3125 inches diameter fits standard chucks and holders

Compatibility

Designed as a general-purpose replacement and production reamer for standard No. 5 taper pin hole applications. Fits straight-shank tool holders and drill chucks accepting a 0.3125 inch shank diameter.

Installation Notes

This reamer should be operated by a qualified machinist or maintenance technician using a drill press, milling machine, or brace at a low, controlled feed rate. Secure the workpiece fully before reaming to prevent movement and ensure hole concentricity. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality. Never force the reamer through an undersized hole in a single pass; step up bore diameter incrementally when removing significant material.
