Hertel 83247056 Chucking Reamer Wire 58 0.0420 in Solid Carbide

Product Description

The HERTEL 83247056 is a solid carbide chucking reamer ground to wire size 58, with a decimal diameter of 0.0420 inches and a diameter tolerance of 0.0000 to 0.0002 inches. It features a straight flute geometry and a straight cylindrical shank, making it suitable for use in drill presses, CNC machining centers, and manual chucking setups. With an overall length of 1.5 inches and a flute length of 0.375 inches, this reamer is sized for precision finishing of small bores. Machinists and toolroom professionals install this tool when tight hole tolerances are required in production or maintenance operations.

This reamer is used in precision machining applications where a wire-gauge-size hole must be brought to a final, closely toleranced diameter. Its compact size suits close-tolerance work in small workpieces, jig and fixture components, and instrument-class parts. The right-hand cutting direction is compatible with standard machine spindle rotation. The bright, uncoated finish is appropriate for use on non-ferrous metals, plastics, and other materials where coated tooling is not required or preferred.

Key Features

• Solid carbide construction provides rigidity and wear resistance in small-diameter reaming applications
• Wire size 58 diameter of 0.0420 inches with a tolerance of 0.0000 to 0.0002 inches for tight bore control
• Straight flute design suits a range of workpiece materials and delivers consistent chip clearance
• Straight cylindrical shank allows secure clamping in standard collet chucks and drill chucks
• Right-hand cutting direction matches standard machine spindle rotation
• Bright uncoated finish preserves dimensional accuracy and suits general-purpose finishing cuts

Compatibility

Designed as an OEM-style precision chucking reamer for use in drill presses, CNC machining centers, and manual chucking setups requiring a wire size 58 finished bore diameter.

Installation Notes

This tool is installed and used by machinists and toolroom technicians. Power down and lock out the machine spindle before loading or removing the reamer from the chuck. Secure the straight shank firmly in a collet or drill chuck rated for the tool diameter before initiating any cut. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
