Hertel 72401995 Taper Pin Reamer 2/0 Hss 4 Flutes

Product Description

The HERTEL 72401995 is a taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Manufactured from high-speed steel with a bright, uncoated finish, this tool delivers reliable performance in general-purpose machining applications. It features a 2/0 taper pin size with a small end diameter of 0.1137 inches and a large end diameter of 0.1462 inches. The spiral flute geometry with right-hand cut and left-hand spiral direction helps draw chips away from the cutting edge during operation. Machinists, toolroom technicians, and maintenance professionals use this reamer for precision hole work in metal fabrication and mechanical assembly.

This reamer is suited for general-purpose hole finishing and shaping tasks where a 2/0 taper pin fit is required. It is commonly used in manual machining, drill press, or lathe applications for producing tapered holes in steel, aluminum, and similar machinable materials. The square shank allows positive drive in compatible tool holders. With a taper rate of 1:48, it conforms to standard taper pin specifications used across industrial maintenance and production machining environments.

Key Features

• 2/0 taper pin size with 1:48 taper rate for standard taper pin fitment
• High-speed steel construction for general-purpose metal cutting
• 4 spiral flutes with right-hand cut and left-hand spiral direction for efficient chip evacuation
• Bright uncoated finish suitable for a wide range of machinable materials
• Square shank provides positive drive engagement in compatible holders
• Compact overall length of 2.5625 inches for use in confined setups

Compatibility

Designed as a standard 2/0 taper pin reamer for use in drill presses, lathes, and manual machining setups that require a 1:48 taper pin hole finish.

Installation Notes

This tool should be installed and used by qualified machinists or toolroom technicians familiar with reaming operations. Secure the workpiece and ensure the tool holder is compatible with a square shank before beginning. Always reduce spindle speed compared to twist drilling and apply cutting fluid to extend tool life and improve finish quality. Do not force the reamer through hardened materials beyond the tool rating for high-speed steel.
