Hertel MR34-0504.406 Chucking Reamer 1.28mm Solid Carbide

Product Description

The HERTEL MR34-0504.406 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 1.28 mm diameter, 50 mm overall length, and a 10 mm spiral flute length, this reamer is built for tight-tolerance work where surface finish and dimensional accuracy are critical. The solid carbide construction provides rigidity and wear resistance suited for demanding production environments. A bright, uncoated finish is standard. This tool is installed by machinists and CNC operators in shop and production settings.

This chucking reamer is used in precision machining operations requiring accurate hole sizing in the 1.00 mm to 2.00 mm diameter range. The right-hand cutting direction with left-hand spiral flutes helps pull chips away from the cutting edge, which is beneficial in blind-hole and through-hole applications. The straight cylindrical shank allows direct mounting in standard drill chucks, collet chucks, and tool holders. Typical applications include finishing reamed holes in ferrous and non-ferrous metals, alloys, and similar materials.

Key Features

• Solid carbide construction for rigidity and extended tool life
• 1.28 mm reamer diameter with tolerance of 0.0000 to +0.0003 mm for precise hole finishing
• Left-hand spiral flutes with right-hand cutting direction aid in chip evacuation
• 4 flutes provide a balance of cutting efficiency and surface finish quality
• Straight cylindrical shank for compatibility with standard chucks and collet systems
• Bright, uncoated finish — no coating buildup to affect critical dimensions

Compatibility

Designed for use in standard drill chucks, collet chucks, and floating holders accepting straight cylindrical shanks; suitable for precision hole finishing in the 1.00 mm to 2.00 mm reamer diameter range.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with precision reaming practices. Ensure the machine spindle and tool holder are clean and properly seated before mounting the reamer. Power down and de-energize the machine before changing or setting tooling. Do not exceed the recommended feeds and speeds for the work material, and verify runout is within acceptable limits prior to production use.
