Hertel MR34-0575.406 Chucking Reamer 1.46mm Spiral Solid Carbide

Product Description

The HERTEL MR34-0575.406 is a solid carbide chucking reamer designed for precision hole finishing in demanding machining applications. With a 1.46 mm diameter and a tight tolerance of 0.0000 to +0.0003 mm, this reamer delivers consistent, accurate bore sizing. The four-flute spiral design with left-hand spiral direction and right-hand cutting action improves chip evacuation and surface finish quality. At 50 mm overall length with a 10 mm flute length, it fits standard chucking setups in CNC and manual machine environments. The bright, uncoated solid carbide construction offers rigidity suited to finishing tight-tolerance bores in ferrous and non-ferrous materials.

This reamer is intended for machine-tool use in production and toolroom environments where precise hole sizing is required. The straight cylindrical shank allows direct mounting in collet chucks, drill chucks, or floating reamer holders on machining centers, lathes, and drill presses. It is well suited to finishing pre-drilled or bored holes in applications requiring exact fit for pins, bushings, or close-tolerance assemblies. Machinists and toolroom operators working with small-diameter bores in the 1.00 mm to 2.00 mm range will find this reamer appropriate for their sizing requirements.

Key Features

• 1.46 mm reamer diameter with tolerance of 0.0000 to +0.0003 mm for precise bore sizing
• Solid carbide construction provides rigidity and wear resistance
• Four-flute spiral geometry with left-hand spiral and right-hand cut for efficient chip removal
• Bright, uncoated finish suitable for a range of workpiece materials
• Straight cylindrical shank for compatibility with standard chucking systems
• 50 mm overall length with 10 mm flute length for controlled engagement in shallow bores

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank collet and drill chuck holders on CNC machining centers, lathes, and drill presses requiring a 1.46 mm finished bore diameter.

Installation Notes

Chucking reamers should be installed and operated by qualified machinists familiar with cutting tool setup and machine tool operation. Ensure the machine spindle is fully stopped and the tool holder is properly secured before mounting or removing the reamer. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain bore finish quality. Follow shop-standard feeds and speeds for solid carbide reamers in the applicable diameter range.
