Hertel MR46-0988.563 Chucking Reamer 0.0988 in Carbide

Product Description

The HERTEL MR46-0988.563 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. With a 0.0988 inch diameter and a reamer diameter tolerance of 0.0000 to +0.0003 mm, this tool delivers consistent, accurate bores in hardened and abrasive materials. The bright polished finish reduces friction and aids chip evacuation. It features a straight shank for direct chuck mounting and a left-hand spiral flute geometry with right-hand cutting direction, a combination that helps pull chips away from the cutting edge during operation. Machinists and toolroom technicians working in CNC or manual setups will find this reamer suited for close-tolerance production work.

This chucking reamer is intended for finish reaming of small-diameter holes in metalworking environments including job shops, tool rooms, and production machining operations. The 0.0988 inch diameter places it in the 2.00 to 3.00 mm diameter range, making it appropriate for precision bores in steel, cast iron, aluminum, and similar machinable materials where dimensional accuracy is critical. The 2.0078 inch flute length provides adequate cutting engagement for through-holes and shallow blind holes in typical workpiece thicknesses.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive materials
• 0.0988 inch diameter with tolerance of 0.0000 to +0.0003 mm for precision hole sizing
• 4-flute left-hand spiral design with right-hand cutting direction for controlled chip flow
• Bright polished coating reduces friction and aids chip clearance
• Straight shank compatible with standard drill chucks and collet holders
• Overall length of 2.9527 inches with a 2.0078 inch flute length for compact reach

Compatibility

Designed as an OEM-style chucking reamer for use with standard straight-shank drill chucks and collet-style toolholders accepting a 0.0988 inch shank diameter in CNC and manual machine tool setups.

Installation Notes

Installation and operation of this reamer should be performed by a qualified machinist familiar with cutting tool setup and machine tool operation. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the chuck or collet. Verify runout with a dial indicator before production use to confirm seating and minimize tool deflection. Always apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality.
