Hertel 45676806 Chucking Reamer 0.439 in Solid Carbide

Product Description

The HERTEL 45676806 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 0.439 inches and a 4-inch overall length, this tool delivers tight-tolerance bore sizing in a single pass. The straight flute geometry and bright polished finish reduce friction and promote clean chip evacuation. Six flutes provide a high cutting edge count, improving surface finish and dimensional accuracy in the finished bore. It is installed using a standard straight shank chuck on a drill press, lathe, or CNC machining center.

This chucking reamer is suited for production and maintenance machining environments where consistent hole diameter control is required. The 0.439-inch diameter makes it appropriate for finishing drilled holes to close tolerances in steel, cast iron, aluminum, and similar machinable materials. Machinists and toolroom technicians working in job shops, manufacturing facilities, or maintenance departments are the typical end users. The right-hand cutting direction is compatible with standard spindle rotation on most machine tools.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• 0.439-inch reamer diameter for precise bore sizing
• 6 straight flutes for smooth cutting action and improved surface finish
• Bright polished coating reduces friction and aids chip removal
• Straight shank for direct chuck mounting on drill presses, lathes, and machining centers
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as an OEM-style replacement or direct tooling selection for straight-shank chuck holders on drill presses, engine lathes, and CNC machining centers requiring a 0.439-inch diameter chucking reamer.

Installation Notes

This reamer is installed by a machinist or toolroom technician into a straight-shank drill chuck or collet holder. Ensure the machine spindle is fully stopped and power is off before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality. Do not run at drill speeds — reamers require reduced RPM and controlled feed rates per standard machining practice for the material being cut.
