Hertel MR46-1000.563 Chucking Reamer 2.54mm Spiral Flute

Product Description

The HERTEL MR46-1000.563 is a solid carbide chucking reamer designed for precision hole finishing in machining applications. With a 2.54 mm reamer diameter and a bright polished finish, this tool delivers tight dimensional control, holding a diameter tolerance of 0.0000 to +0.0003 mm. The spiral flute geometry with left-hand spiral direction and right-hand cutting action helps evacuate chips efficiently while reducing chatter during the reaming pass. At 75 mm overall length with a 14 mm flute length and a straight shank, it is sized for use in CNC machining centers, lathes, and drill presses where a collet or drill chuck provides secure tool holding.

This chucking reamer is suited for precision bore finishing in ferrous and non-ferrous materials where hole diameter accuracy and surface finish are critical. It is typically used in production machining environments, toolroom operations, and precision fabrication shops. The solid carbide construction makes it appropriate for harder workpiece materials and high-speed spindle applications where a high-speed steel tool would wear prematurely. Machinists and CNC operators handling close-tolerance bores in the 2.54 mm range will find this tool a direct fit for that application.

Key Features

• Solid carbide construction for extended tool life in demanding materials
• 2.54 mm reamer diameter with a tolerance of 0.0000 to +0.0003 mm for precision bore sizing
• 6-flute spiral geometry with left-hand spiral and right-hand cut for efficient chip evacuation
• Bright polished coating for reduced friction and improved surface finish in the bore
• Straight shank compatible with standard collets and drill chucks
• 75 mm overall length with 14 mm flute length suited to shallow-to-medium depth bores

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in CNC machining centers, manual lathes, and drill presses equipped with standard straight-shank tool holders or collet chucks accepting the 2.54 mm shank diameter.

Installation Notes

Chucking reamers of this type are installed and removed by qualified machinists or CNC operators following standard machine lockout and spindle-stop procedures before tool changes. Ensure the straight shank is fully seated and securely clamped in the collet or chuck before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not use this reamer to remove excessive stock — pre-drill or bore the hole to within the recommended allowance before reaming.
