Hertel 79890406 Chucking Reamer 0.2280 in Solid Carbide

Product Description

The HERTEL 79890406 is a solid carbide chucking reamer designed to finish-ream precision holes to a No. 1 wire gauge diameter of 0.2280 inches. Built from solid carbide throughout, this reamer delivers consistent bore accuracy with a diameter tolerance of 0.0000 to 0.0002 inches, making it well-suited for applications where tight hole tolerances are required. The straight flute geometry and right-hand cut produce a clean, controlled reaming action. Overall length is 3 inches with a 1-inch flute length. The bright, uncoated finish indicates no additional surface treatment, leaving the carbide substrate exposed for direct visual inspection of cutting edge condition.

This chucking reamer is used in machine shop and precision manufacturing environments where bored or drilled holes must be brought to a final finished diameter. The straight cylindrical shank seats securely in standard drill chucks, collet chucks, or CNC toolholders. Typical applications include finish-reaming holes in ferrous and non-ferrous metals, plastics, and similar machinable materials where dimensional accuracy and smooth surface finish are the primary requirements. It is installed and operated by machinists, toolroom technicians, and CNC operators.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming operations
• Reamer diameter of 0.2280 inches (No. 1 wire gauge) with a tolerance of 0.0000 to 0.0002 inches
• 4-flute straight flute geometry for stable, chatter-resistant cutting action
• Right-hand cutting direction compatible with standard spindle rotation
• Bright, uncoated finish allows direct inspection of cutting edges before and after use
• Straight cylindrical shank fits standard chucks and collet toolholding systems

Compatibility

Designed as a standard chucking reamer with a straight cylindrical shank, this tool is compatible with drill chucks, ER collet chucks, and similar toolholding systems capable of accepting a straight shank of corresponding diameter on manual or CNC machine tools.

Installation Notes

Chucking reamers should be installed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is locked before inserting or removing the reamer. Verify shank seating and runout with a dial indicator before commencing reaming operations. Use appropriate cutting fluid for the workpiece material to extend cutting edge life and achieve the specified surface finish.
