Hertel MR46-0949.563 Chucking Reamer 2.41mm Solid Carbide

Product Description

The HERTEL MR46-0949.563 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 2.41 mm reamer diameter and a tight tolerance of 0.0000 to +0.0003 mm, this tool delivers consistent, accurate bore dimensions in production environments. The four-flute spiral design with a left-hand spiral direction and right-hand cutting action provides smooth chip evacuation and reduces chatter during the reaming pass. At 75 mm overall length with a 14 mm flute length, it is suited for shallow-to-moderate depth holes. The bright polished finish minimizes friction and helps extend tool life in ferrous and non-ferrous materials. Machinists, tool-and-die makers, and CNC operators are the primary users of this tool.

This chucking reamer is intended for precision reaming operations on machining centers, CNC lathes, and drill presses where a straight shank setup is used. The 2.41 mm diameter falls within the 2.00 to 3.00 mm diameter range and is well suited for finishing close-tolerance holes in production runs or prototype work. The straight shank allows direct mounting in collet chucks, drill chucks, or reamer holders without adapters. It is appropriate for both job shop and production floor environments requiring repeatable bore quality.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• 2.41 mm diameter with tolerance of 0.0000 to +0.0003 mm for tight bore accuracy
• Four flutes with left-hand spiral direction and right-hand cutting action for smooth chip flow
• Bright polished finish reduces built-up edge and extends tool life
• Straight shank for direct mounting in standard collet or drill chuck setups
• 75 mm overall length with 14 mm flute length for controlled reaming depth

Compatibility

Designed as a standard straight-shank chucking reamer compatible with collet chucks, drill chucks, and reamer holders sized for the straight shank diameter on CNC machining centers, lathes, and drill presses.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations and machine tool setup. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the reamer from the holder. Secure the straight shank firmly in a collet or chuck with adequate clamping force to prevent slippage during the cut. Always use appropriate cutting fluid for the workpiece material to maintain bore finish quality and extend tool life.
