Value Collection 557u 2 Taper Pin Reamer Size 2 Hss

Product Description

The VALUE COLLECTION 557u 2 is a Size 2 taper pin reamer designed for hole enlarging, hole finishing, and hole shaping operations in metalworking applications. Built from high-speed steel with a bright, uncoated finish, this reamer produces accurate tapered holes sized to accept standard No. 2 taper pins. The spiral flute geometry with left-hand spiral direction promotes smooth chip evacuation during right-hand cutting. Small end diameter measures 0.1605 inches, large end diameter measures 0.2008 inches, and overall length is 3.1875 inches. The square shank seats securely in a tap wrench or compatible holder for controlled hand reaming.

This reamer is used in machine shops, maintenance facilities, and production environments where taper pins are employed to secure collars, hubs, and other components to shafts. It is suited for general-purpose work in steel, cast iron, aluminum, and similar machinable materials. Typical users include machinists, tool-and-die makers, and maintenance technicians performing both new fabrication and repair work on mechanical assemblies that rely on taper pin fastening.

Key Features

• High-speed steel construction for durability across general-purpose metalworking operations
• Spiral flute, left-hand spiral direction promotes chip clearance during right-hand cutting
• Taper rate of 1:48 conforms to standard taper pin geometry for Size 2 applications
• Square shank provides positive drive and precise control in a tap wrench or brace
• Bright, uncoated finish suitable for use with cutting fluid in most common workpiece materials
• Compact overall length of 3.1875 inches with a 1.9375-inch flute length for accurate, controlled stock removal

Compatibility

Designed as an OEM-style replacement or standard tooling option for applications requiring a Size 2 taper pin reamer with a 1:48 taper rate and a 0.2031-inch square shank diameter.

Installation Notes

This reamer is installed and operated by machinists or maintenance technicians using a tap wrench or suitable brace. Secure the workpiece firmly before reaming to prevent movement. Apply an appropriate cutting fluid throughout the operation to reduce heat buildup and extend tool life. Advance the reamer steadily with consistent pressure and avoid reversing under load, which can damage cutting edges.
