Hertel 79889812 Chucking Reamer 0.23 in Solid Carbide

Product Description

The HERTEL 79889812 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a 0.23-inch reamer diameter and a tight tolerance of 0.0000 to 0.0002 inches, this tool delivers accurate, repeatable bore sizing in production and job-shop environments. The straight flute geometry and right-hand cutting direction make it well suited for through-hole and blind-hole reaming in a range of ferrous and non-ferrous materials. Machinists and toolroom technicians install this reamer in CNC machining centers, manual mills, and drill presses using a standard straight-cylindrical shank chuck mount.

This chucking reamer is intended for precision reaming operations where tight dimensional control is required. The 1-inch flute length and 3-inch overall length suit short to medium depth holes in workpieces typically encountered in general machining, toolroom, and production floor environments. The bright uncoated finish is appropriate for use with cutting fluids on a variety of base materials. It is sold individually and sized for applications falling within the 0.2000 to 0.2499-inch reamer diameter range.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.23-inch diameter with a tolerance of 0.0000 to 0.0002 inches for accurate bore sizing
• 4-flute straight flute design for smooth cutting action and chip clearance
• Right-hand cut with straight-cylindrical shank for standard chuck mounting
• Bright uncoated finish compatible with a wide range of cutting fluids and materials
• 3-inch overall length with 1-inch flute length for short to medium depth holes

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank chuck holders on CNC machining centers, manual mills, and drill presses requiring a 0.23-inch finished bore diameter.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or toolroom technician. Secure the straight-cylindrical shank firmly in a compatible chuck and verify runout before beginning the cut. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish. Do not exceed the recommended feed rate or depth of cut for solid carbide tooling in your machine's operating parameters.
