Hertel MR34-0535.406 Chucking Reamer 1.36mm Solid Carbide

Product Description

The HERTEL MR34-0535.406 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 1.36 mm (0.0535 inches) and an overall length of 50 mm (1.969 inches), this tool produces tight-tolerance bores with a diameter tolerance of 0.0000 to +0.0003 mm. The 4-flute spiral configuration with a left-hand spiral direction and right-hand cutting action supports chip evacuation during through-hole reaming operations. The bright, uncoated solid carbide construction provides rigidity and wear resistance when working with ferrous and non-ferrous materials. Machinists and tool-and-die professionals install this reamer in CNC machining centers and drill presses using standard collet or chuck toolholding systems.

This chucking reamer is suited for precision reaming of small-diameter holes in production machining environments, tool and die shops, and aerospace or medical component manufacturing where bore diameter accuracy is critical. The straight cylindrical shank allows direct mounting in collet chucks or precision drill chucks. The 10 mm flute length (0.394 inches) targets shallow-to-moderate depth bores typical in small precision components. It is not configured as a dowel pin reamer or an over/under size reamer, making it appropriate for standard on-size hole finishing to nominal diameter.

Key Features

• 1.36 mm (0.0535 inch) reamer diameter with a tolerance of 0.0000 to +0.0003 mm for precise bore finishing
• Solid carbide construction for rigidity and extended tool life in demanding materials
• 4-flute spiral design with left-hand spiral and right-hand cutting direction for effective chip management
• Bright, uncoated finish suitable for use with cutting fluids across a range of workpiece materials
• Straight cylindrical shank compatible with standard collet and drill chuck toolholding
• 10 mm flute length targets shallow precision bores in small components

Compatibility

Designed for use in CNC machining centers, drill presses, and manual mills equipped with collet chucks or precision drill chucks accepting a straight cylindrical shank at the specified diameter.

Installation Notes

This reamer should be installed by a qualified machinist familiar with precision toolholding practices. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing the tool from the chuck. Use appropriate cutting fluid for the workpiece material to promote tool life and bore surface finish. Do not use this reamer for initial hole creation; always pre-drill to the correct pilot diameter before reaming to size.
