Value Collection 556U 10 Taper Pin Reamer Size 10 Hss

Product Description

The VALUE COLLECTION 556U 10 is a straight-flute taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard No. 10 taper pins. Machined from high speed steel with a bright, uncoated finish, this reamer provides the hardness and edge retention needed for general-purpose metalworking applications. The small end diameter measures 0.5799 inches and the large end measures 0.7216 inches, following a 1:48 taper rate. With an overall length of 9.3125 inches and a 6.8125-inch flute length, it offers ample cutting surface for through-hole and blind-hole operations in ferrous and non-ferrous materials.

This reamer is suited for machine shops, maintenance facilities, and production environments where taper pin holes must be accurately sized and finished. It is used in applications involving pin-and-hole assemblies on shafts, gears, levers, and structural components. The 5/8-inch square shank provides positive drive in manual and machine-held setups. Right-hand cutting direction makes it compatible with standard drill press and lathe spindle rotation. General-purpose performance rating makes it appropriate for a wide range of materials encountered in typical shop work.

Key Features

• No. 10 taper pin size with a 1:48 taper rate for precise tapered hole sizing
• High speed steel construction for durability and edge retention across common workpiece materials
• Straight flute geometry for smooth cutting action in through and blind hole applications
• Bright, uncoated finish suitable for use with cutting fluids in general-purpose operations
• Square shank provides positive torque transfer in drill press, lathe, or hand brace setups
• Right-hand cut matches standard spindle rotation without requiring special toolholding

Compatibility

Designed as a general-purpose taper pin reamer for No. 10 standard taper pins in machine shop, maintenance, and assembly applications requiring a 1:48 taper ratio.

Installation Notes

This tool is typically operated by machinists or maintenance technicians using a drill press, lathe tailstock, or hand brace. Secure the workpiece firmly before reaming and apply a suitable cutting fluid to extend tool life and improve surface finish. Always ream progressively, removing material in multiple light passes rather than forcing the reamer in a single pass. Inspect the finished hole with the mating taper pin before assembly to confirm proper fit and seating.
