Hertel MR34-0618.406 Chucking Reamer 1.57mm Solid Carbide

Product Description

The HERTEL MR34-0618.406 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 1.57 mm reamer diameter, a 50 mm overall length, and a 10 mm spiral flute length, this tool delivers tight tolerances in small-bore work. The bright, uncoated solid carbide construction provides rigidity and wear resistance suited to close-tolerance reaming passes. The four-flute spiral configuration with left-hand spiral direction and right-hand cutting direction reduces chatter and promotes smooth chip evacuation. Machinists and tool-and-die professionals working on precision components, jigs, or fixtures will find this reamer fits standard CNC and manual chucking setups.

This chucking reamer is built for finishing operations where hole diameter control is critical. It is suited to light material removal passes in ferrous and non-ferrous metals, plastics, and similar machinable materials. The straight shank makes it compatible with standard drill chucks and collet holders commonly found in machining centers, lathes, and drill presses. The reamer diameter tolerance of 0.0000 to +0.0003 mm makes it appropriate for tight-fit dowel and bearing bore applications in precision manufacturing environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 1.57 mm reamer diameter with a tolerance of 0.0000 to +0.0003 mm
• Four flutes with left-hand spiral direction for reduced chatter and smooth chip flow
• Right-hand cutting direction for standard forward-feed operation
• Bright, uncoated finish — no coating buildup to affect bore geometry
• Straight shank compatible with standard drill chucks and collet holders

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard straight-shank chuck and collet tooling systems across CNC machining centers, manual lathes, and drill presses.

Installation Notes

Installation and use should be performed by qualified machinists familiar with precision reaming operations. Secure the straight shank firmly in a drill chuck or collet holder before use and verify runout before taking a finishing pass. Always deburr and pre-drill the bore to near-final size before reaming; this tool is designed for light finishing cuts only. Follow applicable shop safety procedures and machine guarding requirements when operating rotating cutting tools.
