Value Collection 556U3/0 Taper Pin Reamer 3/0 Hss

Product Description

The VALUE COLLECTION 556U3/0 is a taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard 3/0 taper pins. Manufactured from high-speed steel with a bright, uncoated finish, this reamer features a straight flute geometry and right-hand cut direction. The small end diameter measures 0.1029 inches and the large end measures 0.1302 inches, with a taper rate of 1:48. The square shank provides positive drive engagement in a standard brace or machine holder. Overall length is 2.3125 inches with a flute length of 1.3125 inches. This tool is suited for general-purpose reaming operations in machine shops, maintenance environments, and assembly work.

This taper pin reamer is used wherever precision tapered holes must be sized to accept 3/0 standard taper pins in metal components. Typical applications include shaft-to-hub connections, linkage assemblies, and mechanical joints requiring a secure, removable pin retention. The tool is appropriate for use in drill presses, manual braces, or hand-held tapping fixtures. Machinists, tool-and-die technicians, and maintenance mechanics regularly specify this size for light-to-medium material removal in ferrous and non-ferrous workpieces.

Key Features

• High-speed steel construction provides durability across ferrous and non-ferrous materials
• Straight flute geometry suited for general-purpose through-hole reaming
• Right-hand cut direction compatible with standard machine and hand-drive setups
• Square shank delivers positive torque transfer and secure chuck engagement
• Bright, uncoated finish allows direct visual inspection of cutting edge condition
• 1:48 taper rate matches standard taper pin specifications for accurate pin seating

Compatibility

Designed as an OEM-style replacement and general-purpose taper pin reamer for applications requiring a 3/0 pin size with a 1:48 taper rate in standard machine or hand-drive setups.

Installation Notes

Machinist or maintenance technician installation is recommended. Secure the workpiece firmly before reaming to prevent movement and ensure hole alignment. Power down and de-energize any equipment before reaming holes in installed assemblies. Use cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality; avoid forcing the reamer through the material, as progressive light passes produce more accurate results.
