Hertel 2058618 Taper Pin Reamer Set 5 to 0 Pin Hss

Product Description

The HERTEL 2058618 is a six-piece taper pin reamer set covering pin sizes 7/0 through 0, with reamer diameters ranging from 0.0666 to 0.1638 inches and small end diameters ranging from 0.0497 to 0.1287 inches. Each reamer features a helical flute geometry with a right-hand cut, a straight shank, and a bright polished finish. The tools are manufactured from high speed steel, providing the hardness and wear resistance needed for consistent, accurate taper pin hole finishing in metal fabrication, maintenance, and repair applications. The set is suited for machinists, tool and die makers, and maintenance technicians working on precision assemblies.

This set is designed for reaming and finishing taper pin holes in a range of small to mid-size mechanical assemblies, including shafts, hubs, and machine components where taper pin fastening is the standard method. The six included reamers allow a single kit to cover a broad pin size range without switching between individual tools. Typical applications include general machine shop work, industrial maintenance, and precision equipment repair where exact hole geometry is required for proper taper pin seating and retention.

Compatibility

Designed as an OEM-style replacement or general-use set compatible with standard taper pin sizing per ASME and industrial machine tool specifications for pin sizes 7/0 through 0.

Installation Notes

Taper pin reaming is typically performed by machinists or maintenance technicians using a manual or machine-driven straight-shank chuck. Always secure the workpiece firmly and ensure the reamer is aligned axially with the pilot hole before advancing. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Do not force the reamer through an undersized hole in a single pass; step up incrementally where stock removal is significant.
