Hertel 45675931 Chucking Reamer 0.301 in Solid Carbide

Product Description

The HERTEL 45675931 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.301 inches and a 1-1/8 inch straight flute length, this tool delivers accurate, repeatable bore sizing in a wide range of materials. The bright polished finish reduces friction and aids chip evacuation. Featuring 6 right-hand flutes and a straight shank, it is intended for use in CNC machining centers, drill presses, and lathes where close-tolerance hole finishing is required. Machinists and toolroom technicians are the primary users of this reamer.

This chucking reamer suits precision bore finishing operations in metalworking applications where tight dimensional tolerances are critical. It is well suited for production runs and toolroom work involving steel, cast iron, aluminum, and similar machinable materials. The 3-1/4 inch overall length and straight shank allow straightforward chuck mounting with standard toolholders. Its solid carbide construction provides superior hardness and wear resistance compared to high-speed steel alternatives, making it a practical choice for high-volume or abrasive material applications.

Key Features

• Solid carbide construction for high hardness and extended tool life
• 0.301 inch reamer diameter for precision bore sizing
• 6 straight right-hand flutes for smooth, accurate cutting action
• Bright polished finish reduces friction and aids chip flow
• Straight shank for direct chuck mounting without adapters
• 1-1/8 inch flute length with 3-1/4 inch overall length

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, drill presses, and lathes equipped with standard straight-shank toolholders accepting a 0.301 inch diameter reamer.

Installation Notes

This reamer should be installed by a qualified machinist following standard toolroom procedures. Secure the straight shank firmly in a precision chuck or collet before operation, and ensure the workpiece is properly fixtured and the spindle is at a safe, recommended reaming speed for the material being cut. Always power down and lock out the machine before changing tooling. Do not use this tool as a drill — reamers are finishing tools and require a pre-drilled or bored hole slightly undersized relative to the final dimension.
