Hertel 72037823 Chucking Reamer 0.782 in Hss 8 Flute

Product Description

The HERTEL 72037823 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.7820 inches and an overall length of 9.5 inches, it delivers accurate bore sizing in drill press, lathe, and CNC machining setups. The 8-flute straight configuration provides a smooth, consistent cut with minimal chatter, and the bright uncoated finish is suited for a wide range of general-purpose materials. The straight-cylindrical shank allows secure mounting in standard chucks and collets without special tooling adapters.

This chucking reamer is intended for machine reaming operations where a precise, finished bore is required after drilling. It is used in metalworking shops, maintenance and repair operations, and production machining environments. The 2.5-inch flute length accommodates typical through-hole and blind-hole finishing tasks in mild steel, cast iron, aluminum, and similar machinable materials. Right-hand cutting direction makes it compatible with standard spindle rotation on most machine tools.

Key Features

• 0.7820-inch reamer diameter for precise bore finishing
• 8 straight flutes provide smooth cutting action and reduced chatter
• HSS construction offers good wear resistance across general-purpose materials
• Bright uncoated finish suitable for use with cutting fluids and standard coolants
• Straight-cylindrical shank mounts directly in drill chucks and collet holders
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as an OEM-style machine reamer for use in drill presses, lathes, and CNC machining centers equipped with standard chuck or collet toolholding systems accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by qualified machinists or tool and die professionals. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the reamer from the chuck or collet. Use appropriate cutting fluid for the material being reamed to extend tool life and improve finish quality. Pre-drill holes to the correct size before reaming, as chucking reamers are not designed to remove large amounts of stock.
