Hertel 45676319 Chucking Reamer 0.349 in Solid Carbide

Product Description

The HERTEL 45676319 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a reamer diameter of 0.349 inches and an overall length of 3.5 inches, this tool delivers accurate, repeatable bore sizing in production and job-shop environments. The 6-flute straight configuration provides smooth cutting action and consistent chip evacuation. The bright uncoated finish is standard for solid carbide reamers used across a wide range of workpiece materials. This tool is installed and operated by machinists and tooling technicians using CNC machining centers, lathes, or drill presses.

This chucking reamer is suited for finishing through-holes and blind holes in metalworking applications where tight diameter tolerances are required. The straight cylindrical shank allows secure clamping in standard drill chucks, collet holders, or floating reamer holders. The right-hand cutting direction is compatible with conventional machine spindle rotation. Typical applications include production runs on ferrous and non-ferrous metals where hole quality and size consistency are critical. It is not configured as a dowel pin reamer and is not an over or under size variant.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• 6 straight flutes for smooth, consistent chip flow and surface finish
• 0.349 inch reamer diameter with a 1.25 inch flute length for controlled cutting depth
• Straight cylindrical shank for compatibility with standard chucking and collet systems
• Right-hand cut matches conventional machine spindle direction
• Bright uncoated finish suitable for use with cutting fluids across varied workpiece materials

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.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the tool is securely clamped in the holder before engaging the workpiece. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Verify spindle speed and feed rate are within the recommended range for solid carbide reamers at this diameter before beginning the cut.
