Hertel 45676442 Chucking Reamer 0.364 in Solid Carbide

Product Description

The HERTEL 45676442 is a solid carbide chucking reamer designed for precision hole finishing in machining operations. Built with a straight shank and a straight 6-flute configuration, it produces accurate, smooth bores by removing minimal material after a drilled or bored hole has been roughed to size. The 0.364-inch cutting diameter falls within the 0.3500 to 0.3999-inch decimal inch range, making it suitable for close-tolerance work in metals and other machinable materials. At 3.5 inches overall length with a 1.25-inch flute length, this reamer fits standard drill chucks and collets used on CNC machining centers, manual mills, and drill presses. The bright polished finish reduces friction and aids chip evacuation. Right-hand cutting direction is standard for conventional machine spindle rotation.

This chucking reamer is suited for production and job-shop machining environments where precise bore sizing is required. It is commonly used in applications involving ferrous and non-ferrous metals where hole tolerances are tight and surface finish matters. Machinists and CNC operators working on fixture components, hydraulic manifolds, bearing bores, and precision assemblies will find this reamer appropriate for final sizing passes at the 0.364-inch diameter. Solid carbide construction makes it a solid choice for harder workpiece materials where high-speed steel tooling wears prematurely.

Key Features

• 0.364-inch cutting diameter for close-tolerance bore finishing
• Solid carbide construction provides rigidity and wear resistance in demanding materials
• 6-flute straight design promotes accurate sizing and smooth surface finish
• Bright polished finish reduces friction and aids chip flow
• Straight shank compatible with standard drill chucks and collets
• Right-hand cutting direction suits conventional machine spindle rotation

Compatibility

Designed as a standard straight-shank chucking reamer compatible with drill chucks and collets on CNC machining centers, knee mills, and drill presses configured for right-hand cutting tools in the 0.364-inch diameter class.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with reaming parameters and machine setup. Ensure the spindle and workpiece are fully secured before initiating a cut, and select appropriate feed rates and cutting speeds per the workpiece material to avoid tool deflection or chatter. Never use a chucking reamer as a drill to initiate a hole; always ream a pre-drilled or bored hole that is undersized to the appropriate allowance. Proper cutting fluid or coolant application is recommended to extend tool life and maintain bore finish quality.
