Hertel 45676590 Chucking Reamer 0.385 in Solid Carbide

Product Description

The HERTEL 45676590 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining operations. With a diameter of 0.385 inches and a 3.5-inch overall length, this reamer delivers tight dimensional tolerance when finishing drilled or bored holes. The 6-flute straight flute geometry promotes smooth cutting action and consistent chip evacuation. A bright polished finish reduces friction and extends tool life in demanding materials. This tool is installed and used by machinists and tool-and-die professionals working on manual or CNC lathes, drill presses, and machining centers.

This chucking reamer is suited for precision finishing of through-holes and blind holes in steel, cast iron, aluminum, and similar machinable materials. The straight shank allows direct chuck mounting in standard toolholders. With a 1.25-inch flute length, it is best applied to shallow-to-moderate depth finish passes where diameter accuracy and surface finish are critical. It is a common choice in production, job shop, and maintenance machining environments where repeatable bore sizing is required.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to HSS alternatives
• 0.385-inch reamer diameter for precise hole sizing within the 0.3500 to 0.3999 inch range
• 6-flute configuration provides stable cutting action and improved surface finish
• Straight flute design suits a wide range of materials including steel and aluminum
• Bright polished coating minimizes built-up edge and reduces cutting forces
• Straight shank allows easy chuck mounting in standard drill chucks and collets

Compatibility

Designed as an OEM-style machine reamer for use in standard drill chucks, collet holders, and floating reamer holders on CNC machining centers, lathes, and drill presses accepting straight shank tooling.

Installation Notes

Chucking reamers should be installed by qualified machinists familiar with cutting tool setup and speeds and feeds for carbide tooling. Always power down and lock out the spindle before changing or setting tools. Use a floating reamer holder where possible to allow for minor alignment compensation and avoid side loading the reamer. Do not use this reamer as a drill or to remove excessive stock — reamers are finish tools intended for light material removal passes only.
