Hertel 72401961 Taper Pin Reamer Size 5/0 Hss 4 Flute

Product Description

The HERTEL 72401961 is a taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Built from high-speed steel with a bright, uncoated finish, this reamer features four spiral flutes with a left-hand spiral direction and right-hand cutting action. 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 1:48 taper rate conforms to standard taper pin specifications. With an overall length of 2.1875 inches and a square shank measuring 0.1094 inches in diameter, it is suited for use in a tap wrench or brace. This is a general-purpose toolroom and machinist reamer intended for precision hand or machine reaming operations.

This reamer is used wherever standard taper pins are driven into assemblies to lock hubs, collars, or other machine components to shafts. Typical applications include general machining, toolroom work, maintenance, and repair in industrial, manufacturing, and mechanical service environments. It is appropriate for use in both manual and low-speed machine reaming setups where a clean, accurately sized tapered bore is required before pin installation.

Installation Notes

This tool is used by machinists and maintenance technicians. Secure the workpiece firmly before reaming and use cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Apply light, consistent pressure and turn only in the cutting direction to avoid damaging the flutes. Always clear chips frequently during the operation to prevent binding or tool breakage.
