Hertel MR34-0362.281 Chucking Reamer 0.0362 in Solid Carbide

Product Description

The HERTEL MR34-0362.281 is a solid carbide chucking reamer designed for precision hole finishing in close-tolerance machining applications. With a reamer diameter of 0.0362 inches (0.92 mm) and a tolerance of 0.0000 to +0.0003 mm, this tool is built for applications where bore size accuracy is critical. The overall length is 1.9685 inches (50.00 mm), and the flute length measures 0.7087 inches (18.00 mm). Solid carbide construction provides rigidity and wear resistance suited to hard or abrasive workpiece materials. This reamer features a bright polished coating that reduces friction and aids chip evacuation during the reaming operation. It is installed by machinists in CNC machining centers or drill presses via a straight shank chuck.

This chucking reamer is intended for precision reaming of small-diameter bores in ferrous and non-ferrous materials. The 0.0362-inch diameter makes it appropriate for micro-bore and small-hole finishing operations in production and tool-and-die environments. The left-hand spiral flute geometry combined with right-hand cutting direction pulls chips away from the cutting zone, which is a common setup for through-hole reaming where chip control is important. Machinists and toolroom professionals working on precision components, instrument parts, or hydraulic valve bodies will find this diameter range applicable to tight-clearance bore work.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard or abrasive materials
• 0.0362-inch (0.92 mm) diameter with a tolerance of 0.0000 to +0.0003 mm for precise bore sizing
• Left-hand spiral flutes with right-hand cutting direction for effective chip evacuation in through-hole applications
• Bright polished finish reduces friction and improves surface finish in the reamed bore
• 4-flute geometry balances cutting load and surface finish quality
• Straight shank compatible with standard collet chucks and drill chuck holders

Compatibility

Designed as a straight-shank chucking reamer suitable for use in CNC machining centers, manual mills, and drill presses equipped with collet chucks or keyed drill chucks accepting the appropriate shank diameter.

Installation Notes

Chucking reamers are installed and serviced by machinists in machine shop environments. Always power down and lock out the spindle before changing tooling. Secure the straight shank fully within the chuck to the recommended grip depth to prevent runout, and verify chuck concentricity before running. Follow applicable shop safety procedures and manufacturer feeds-and-speeds guidelines for carbide reaming tools; do not use this reamer as a drill to remove stock.
