Hertel MR46-1031.563 Chucking Reamer 2.62mm Solid Carbide

Product Description

The HERTEL MR46-1031.563 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 2.62 mm (0.1031 inch) reamer diameter and a tolerance of 0.0000 to +0.0003 mm, this tool delivers tight, consistent bore sizing. The 75 mm overall length and 14 mm flute length suit it for shallow-to-moderate depth reaming operations. Four spiral flutes with a left-hand spiral direction and right-hand cutting action help evacuate chips efficiently while maintaining surface finish quality. The bright polished coating reduces friction and resists built-up edge. Machinists and toolroom professionals specify this reamer for close-tolerance finish passes on drilled or bored holes.

This chucking reamer is suited for use in CNC machining centers, drill presses, and manual lathes where a straight shank and chuck-held setup is standard. It is appropriate for ferrous and non-ferrous materials where solid carbide tooling is preferred over high-speed steel for improved wear resistance and dimensional repeatability. Typical applications include production runs requiring consistent bore finishes in the 2.00 to 3.00 mm diameter range.

Key Features

• Solid carbide construction for superior wear resistance and rigidity in precision reaming
• 2.62 mm diameter with a tight tolerance of 0.0000 to +0.0003 mm for close-tolerance bore finishing
• 4-flute spiral design with left-hand spiral and right-hand cut for efficient chip evacuation
• Bright polished finish reduces friction and helps prevent built-up edge
• Straight shank for direct chuck mounting on standard machine setups
• Compact 75 mm OAL with 14 mm flute length suited for shallow reaming operations

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank chuck holders on CNC and manual machines where 2.00 to 3.00 mm diameter solid carbide reamers are specified.

Installation Notes

This reamer is installed and serviced by machinists and toolroom technicians. Secure the straight shank firmly in a precision collet or drill chuck rated for the spindle speed before operation. Power down and lock out the machine spindle before inserting or removing the tool. Do not use this reamer to remove excessive stock; finish reaming is a light-material-removal operation following a properly sized drilled or bored hole.
