Hertel 72039548 Chucking Reamer 0.9540 in 8 Flute Hss

Product Description

The HERTEL 72039548 is a straight-flute chucking reamer designed for precision hole finishing in machine shop and production environments. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing across a wide range of materials in both manual and CNC machining applications. The reamer measures 0.9540 inches in diameter with a 10-inch overall length and a 2-5/8 inch flute length. Its straight-cylindrical shank seats securely in standard drill chucks and collet holders. With 8 flutes and right-hand cutting direction, it produces a smooth, dimensionally consistent bore. Machinists, tool-and-die makers, and maintenance professionals are the typical end users for this tool.

This chucking reamer is suited for through-hole and blind-hole reaming operations in ferrous and non-ferrous metals, as well as engineering plastics. It is appropriate for use on drill presses, lathes, and machining centers where a straight-shank tool is required. The 0.9540-inch diameter falls within the 0.7000 to 0.9999 inch reamer diameter range, making it a standard production-class tool for close-tolerance bore finishing work in job shops, maintenance facilities, and manufacturing lines.

Key Features

• 0.9540-inch reamer diameter for precise hole sizing
• HSS construction provides good wear resistance across a broad range of workpiece materials
• 8 straight flutes produce consistent surface finish and dimensional accuracy
• Right-hand cutting direction compatible with standard spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet systems without adapters
• Bright, uncoated finish suitable for use with cutting fluids in general-purpose reaming

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and machining centers that accept straight-cylindrical shank tooling. No specific machine model compatibility was provided by the manufacturer for this part.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with reaming operations. Ensure the workpiece is securely fixtured and the spindle is at the correct speed and feed rate for the material before engaging the reamer. Apply appropriate cutting fluid to extend tool life and improve surface finish. Never reverse spindle direction while the reamer is engaged in the bore.
