Hertel 2058659 Taper Pin Reamer Set 7/0 to 0

Product Description

The HERTEL 2058659 is a taper pin reamer set designed to produce and finish tapered holes for standard taper pin fasteners in precision machining and mechanical assembly work. The set covers pin sizes 7/0 through 0, with reamer large-end diameters ranging from 0.0666 inches to 0.1638 inches and small-end diameters ranging from 0.0497 inches to 0.1287 inches. Each reamer features a helical flute geometry with a left-hand spiral and right-hand cut, ground from high speed steel with a bright polished finish. The set includes six taper pin reamers with a straight shank for use in standard drill presses, milling machines, or hand brace applications.

This set is suited for machinists, millwrights, and tool-and-die professionals working in light manufacturing, maintenance, and repair environments. Taper pin reamers are used when assembling shafts, collars, levers, and similar components that are secured with standard taper pins. The six-piece coverage across sizes 7/0 to 0 makes this set appropriate for small-diameter precision work where exact taper fit and surface finish are critical to assembly integrity.

Key Features

• Six-piece set covering taper pin sizes 7/0 through 0
• Helical flute with left-hand spiral and right-hand cut for smooth chip evacuation
• Ground from high speed steel for hardness and wear resistance
• Bright polished finish reduces friction and aids chip flow
• Straight shank fits standard drill chucks and machine spindles
• Large-end diameters: 0.1638, 0.1798, 0.2008, 0.2294, 0.2604, and 0.2994 inches across the six reamers

Compatibility

Designed for use with standard taper pins sized 7/0 through 0 in precision machining and mechanical assembly applications requiring tapered hole finishing.

Installation Notes

Taper pin reamers are typically operated by machinists or millwrights using a drill press, milling machine, or hand brace at appropriate low speeds with cutting oil applied. Secure the workpiece firmly before reaming to prevent movement. Always clear chips frequently during the reaming operation. Follow applicable shop safety procedures and machine guarding requirements when operating rotary cutting tools.
