Hertel MR34-0567.406 Chucking Reamer 0.0567 in Carbide

Product Description

The HERTEL MR34-0567.406 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance applications. With a reamer diameter of 0.0567 inches (1.44 mm) and a diameter tolerance of 0.0000 to +0.0003 mm, this tool delivers consistent, accurate results in production and toolroom environments. The four-flute spiral configuration with a left-hand spiral and right-hand cutting direction promotes smooth chip evacuation and reduces chatter during the reaming pass. A bright (polished) finish minimizes built-up edge on the cutting faces. Machinists and toolmakers install this reamer in CNC machining centers, drill presses, and manual mills where repeatable bore sizing is required.

This chucking reamer is suited for small-diameter precision hole finishing in ferrous and non-ferrous materials. The straight shank allows direct chuck or collet mounting in standard toolholding systems. With an overall length of 1.9685 inches (50 mm) and a flute length of 0.7087 inches (10 mm), the tool is sized for shallow-to-moderate depth bores typical in instrument components, medical device fixtures, mold work, and precision mechanical assemblies. The compact geometry makes it well suited to benchtop and vertical machining center setups where clearance is limited.

Key Features

• Solid carbide construction for hardness and wear resistance in precision reaming applications
• 0.0567 inch (1.44 mm) diameter with tight tolerance of 0.0000 to +0.0003 mm for accurate bore sizing
• Four-flute spiral design with left-hand spiral and right-hand cutting direction for smooth chip flow
• Bright (polished) coating finish reduces friction and built-up edge on cutting faces
• Straight shank for direct mounting in standard chucks or collets
• Compact 1.9685 inch overall length suitable for close-clearance setups

Compatibility

Designed for use in standard straight-shank toolholding systems including drill chucks and collet holders sized for the 0.0567 inch shank diameter on CNC and manual machine tools.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before loading or removing the reamer from the toolholder. Ensure the shank is fully seated and the chuck or collet is properly tightened before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
