Value Collection 558u5/0 Taper Pin Reamer 5/0 Hss

Product Description

The VALUE COLLECTION 558u5/0 is a straight-shank taper pin reamer designed for enlarging, finishing, and shaping taper pin holes in metal workpieces. Built from high speed steel with a bright, uncoated finish, this reamer features a helical flute geometry that promotes smooth cutting action and clean chip evacuation. It is sized for a 5/0 taper pin, with a small end diameter of 0.0719 inches and a large end diameter of 0.0966 inches. The flute length measures 1.1875 inches and the overall length is 2.1875 inches. Right-hand cutting direction with left-hand spiral flutes reduce chatter and improve surface finish in precision hole work. Machinists and tool-and-die technicians are the primary users.

This reamer is suited for general-purpose taper pin hole preparation in production machining, maintenance, and repair operations. It fits manual drill presses, milling machines, and hand-held drilling equipment with a compatible straight shank holder. The 1:48 taper rate matches the standard taper pin specification for 5/0 pins, making it the correct tool when fitting or replacing taper pins in shafts, collars, and mechanical assemblies that require a precise, repeatable interference fit.

Key Features

• High speed steel construction provides hardness and wear resistance for ferrous and non-ferrous materials
• Helical flute design with left-hand spiral promotes smooth cutting and efficient chip removal
• Right-hand cutting direction compatible with standard machine spindle rotation
• 1:48 taper rate matches standard 5/0 taper pin specification
• Bright, uncoated finish allows visual inspection of cutting edge condition
• Straight shank at 0.1094 inches (7/64 inches) fits standard collets and chucks

Compatibility

Designed as an OEM-style replacement and general-purpose reamer for applications requiring a standard 5/0 taper pin hole with a 1:48 taper rate.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, milling machine, or hand drill with an appropriate straight-shank collet or chuck. Secure the workpiece firmly before reaming and apply a suitable cutting fluid to extend tool life and improve hole finish. Always ream at reduced spindle speed compared to drilling, and advance the tool steadily without forcing. Inspect the cutting edges before use and do not use a damaged or chipped reamer.
