Value Collection 557u5/0 Taper Pin Reamer 5/0 Hss

Product Description

The VALUE COLLECTION 557u5/0 is a taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard 5/0 taper pins. Manufactured from high speed steel with a bright, uncoated finish, this reamer features a spiral flute geometry with a right-hand cutting direction and left-hand spiral for smooth chip evacuation. The small end diameter measures 0.0719 inches and the large end measures 0.0966 inches, conforming to the standard 1:48 taper rate. Machinists and tool-room technicians use this reamer when fitting precision taper pin connections in shafts, hubs, and mechanical assemblies.

This taper pin reamer is suited for general-purpose hole finishing in small-diameter applications, particularly where taper pins are used to secure components on shafts or to align mating parts. The compact overall length of 2.1875 inches and 1.1875-inch flute length make it appropriate for close-tolerance work in light industrial and tool-room environments. The square shank at 0.1094 inches provides positive drive in a standard tap wrench or similar hand-holding tool.

Key Features

• High speed steel construction for durability across a range of workpiece materials
• Spiral flute, left-hand spiral geometry promotes smooth chip removal during reaming
• Right-hand cutting direction for standard forward-rotation use
• 1:48 taper rate matches the standard taper pin specification for 5/0 pins
• Bright, uncoated finish suitable for general-purpose applications
• Square shank for positive drive in a tap wrench or brace

Compatibility

Designed as a general-purpose reamer for producing and finishing holes to accept standard 5/0 taper pins per accepted taper pin sizing conventions.

Installation Notes

Taper pin reamers are typically used by machinists working in manual or hand-reaming operations. Secure the workpiece firmly before reaming and apply cutting fluid to extend tool life and improve finish quality. Use consistent, steady pressure and rotate the reamer without reversing direction under load, as reversing can damage the cutting edges. Always verify the finished hole with the appropriate taper pin before final assembly.
