Hertel 45674769 Chucking Reamer 0.1275 in Solid Carbide

Product Description

The HERTEL 45674769 is a solid carbide chucking reamer designed for precision hole finishing in machining applications. Built with a 0.1275-inch diameter and a straight shank, this reamer delivers consistent, accurate sizing in through-holes and blind holes. The four straight flutes and bright polished finish promote smooth chip evacuation and reduce cutting friction. At 2.25 inches overall length with a 0.625-inch flute length, this compact tool is suited for close-tolerance work in small-bore applications. It is installed and operated by machinists, toolroom technicians, and CNC operators working on ferrous and non-ferrous materials.

This chucking reamer is used in machine tool setups including drill presses, CNC machining centers, lathes, and manual mills. Its straight-shank configuration allows direct mounting in standard drill chucks or collets. The right-hand cutting direction is standard for conventional machine spindle rotation. Applications include precision hole reaming in production and jobshop environments where tight diameter tolerances are required. The bright carbide finish suits use in non-ferrous metals, plastics, and some ferrous materials at appropriate cutting parameters.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.1275-inch reaming diameter for close-tolerance hole finishing
• Four straight flutes with right-hand cutting direction
• Bright polished finish reduces friction and promotes chip flow
• Straight shank fits standard drill chucks and collet holders
• Compact 2.25-inch overall length for small-bore and tight-clearance setups

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle accepting a straight-shank tool of equivalent diameter, including drill chucks, ER collets, and similar toolholding systems.

Installation Notes

This tool is installed by machinists or toolroom technicians. Secure the straight shank firmly in a properly sized collet or drill chuck before operation. Always power down and lock out the machine spindle before changing or adjusting tooling. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life and finish quality. Do not exceed the tool diameter capacity of the chuck or collet holder.
