Hertel MR34-0768.406 Chucking Reamer 1.95mm Solid Carbide

Product Description

The HERTEL MR34-0768.406 is a solid carbide chucking reamer designed for precision hole finishing in close-tolerance machining applications. With a 1.95 mm reamer diameter and a diameter tolerance of 0.0000 to +0.0003 mm, this tool delivers accurate, repeatable results in production environments. The 4-flute spiral design with left-hand spiral direction and right-hand cutting action helps evacuate chips efficiently while maintaining smooth bore surface finish. Overall length is 50 mm with a 10 mm flute length. The bright polished coating reduces friction and aids chip flow. Machinists and toolroom technicians working with small-diameter bores will find this reamer suited to exacting finish reaming work.

This chucking reamer is intended for finish reaming of small-diameter through-holes and blind holes in metal workpieces where tight dimensional tolerances are required. The straight shank allows it to be held in standard drill chucks, collet chucks, or floating reamer holders on CNC machining centers, drill presses, or manual knee mills. It is appropriate for use in precision component manufacturing, tool and die work, and any application requiring a hole diameter in the 1.95 mm range with minimal oversize deviation.

Key Features

• 1.95 mm reamer diameter with a tolerance of 0.0000 to +0.0003 mm for precise hole sizing
• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• 4-flute spiral geometry with left-hand spiral and right-hand cut for efficient chip evacuation
• Bright polished finish to reduce cutting friction and improve surface quality
• Straight shank compatible with standard chucks and collet systems
• 50 mm overall length with 10 mm flute length suited to shallow finish reaming operations

Compatibility

Designed as a standard chucking reamer for use in any machine tool setup accepting a straight-shank small-diameter reamer in the 1.95 mm size range.

Installation Notes

Chucking reamers should be installed by a qualified machinist following established shop safety procedures. Always ensure the machine spindle is fully stopped and locked out before changing or inspecting tooling. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish. Do not use a chucking reamer to remove excessive stock — reamers are finish tools intended for minimal material removal from a pre-drilled or bored hole.
