Value Collection 558u3/0 Taper Pin Reamer 3/0 Pin Hss

Product Description

The VALUE COLLECTION 558u3/0 is a taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard 3/0 taper pins. Made from high speed steel with a bright uncoated finish, this reamer features a helical flute geometry and a straight shank for use in drill presses, lathes, and hand braces. The small end diameter measures 0.1029 inches and the large end measures 0.1302 inches, with a taper rate of 1:48. Overall length is 2.3125 inches with a flute length of 1.3125 inches. Right hand cutting direction with left hand spiral flutes. Installed by machinists, tool and die makers, and maintenance technicians working on precision assemblies.

This reamer is suited for general purpose hole finishing work in machine shops, maintenance facilities, and production environments where taper pin joints are used to secure hubs, collars, and similar components to shafts. The 3/0 pin size targets smaller-diameter applications requiring precise taper alignment. The 9/64 inch straight shank allows compatibility with standard collet chucks and drill press keyless chucks. Typical applications include hole enlarging and final finishing passes where hand-reaming or light machine reaming is required to achieve proper taper pin fit.

Key Features

• High speed steel construction for durability across ferrous and non-ferrous materials
• Helical flute geometry promotes smooth chip evacuation and consistent finish
• Bright uncoated finish suitable for general purpose cutting applications
• 1:48 taper rate matches standard taper pin specifications for size 3/0
• Right hand cut with left hand spiral for reduced chatter during reaming
• Straight 9/64 inch shank fits standard collets and chucks

Compatibility

Designed as an OEM-style replacement or direct-use taper pin reamer for standard 3/0 taper pin applications in general purpose machining and maintenance work.

Installation Notes

This tool is used by machinists and maintenance technicians operating drill presses, lathes, or hand braces. Secure the workpiece firmly before reaming and apply cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Use light, consistent feed pressure to avoid overloading the flutes or deflecting the shank. Inspect the reamed hole with the mating taper pin before pressing to final depth to confirm proper fit.
