Hertel MR34-0461.406 Chucking Reamer 1.17mm Solid Carbide

Product Description

The HERTEL MR34-0461.406 is a solid carbide chucking reamer designed for precision hole finishing in close-tolerance machining applications. With a 1.17 mm reamer diameter and a diameter tolerance of 0.0000 to +0.0003 mm, this tool delivers consistent, accurate results in production environments. The 50 mm overall length and 10 mm flute length make it well-suited for shallow finishing passes. A bright polished coating reduces friction and aids chip flow. Machinists and toolroom professionals install this reamer in CNC machining centers and manual drill presses wherever controlled bore sizing is required.

This chucking reamer is intended for use in metal cutting applications that demand tight diameter control, such as reaming drilled holes to final size for press fits, dowel pin bores, or precision bearing seats. The straight shank allows direct clamping in standard collet chucks or drill chucks. Its compact diameter range of 1.00 mm to 2.00 mm places it in small-bore finishing work common in medical device manufacturing, mold making, and precision instrument production.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• 1.17 mm reamer diameter with a tolerance of 0.0000 to +0.0003 mm for precise bore sizing
• 4-flute spiral flute design with left-hand spiral and right-hand cut for smooth chip evacuation
• Bright polished finish reduces friction and improves surface finish in the reamed bore
• Straight shank compatible with standard collet and drill chuck systems
• 50 mm overall length with 10 mm flute length suited for shallow-depth finishing passes

Compatibility

Designed as an OEM-style chucking reamer replacement for small-bore precision finishing applications in the 1.00 mm to 2.00 mm diameter range.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with precision hole finishing operations. Ensure the machine spindle and workpiece are fully secured before engaging the reamer, and confirm the collet or chuck is clean and properly torqued to prevent runout. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality. Follow shop-specific feeds and speeds guidelines for carbide tooling in the applicable material.
