Hertel 72039241 Chucking Reamer 0.9240 in Hss 8 Flute

Product Description

The HERTEL 72039241 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal fabrication and machining applications. With a 0.9240-inch reamer diameter, 10-inch overall length, and 8 straight flutes in a right-hand cutting direction, this tool delivers accurate, smooth bore sizing in a wide range of materials. The straight-cylindrical shank seats securely in standard lathe or drill press chucks. It carries a bright, uncoated finish and is intended for machinists and toolroom professionals requiring reliable dimensional accuracy on finish-reaming operations.

This chucking reamer is suited for machine shop environments, production floors, and toolroom use where precise hole tolerances are required. It covers the 0.7000 to 0.9999 inch reamer diameter range class and fits applications in both manual and CNC-assisted setups. Typical users include machinists, tool-and-die makers, and maintenance professionals performing bore sizing on ferrous and non-ferrous workpieces. The 2-5/8-inch flute length provides adequate chip clearance for most through-hole and blind-hole finish-reaming tasks at this diameter.

Key Features

• 0.9240-inch reamer diameter for precision hole finishing
• HSS construction provides good wear resistance across common workpiece materials
• 8 straight flutes with right-hand cutting direction for smooth, accurate bore sizing
• Bright, uncoated finish — no added coating thickness to affect dimensional tolerances
• Straight-cylindrical shank for secure seating in standard chucks
• 10-inch overall length accommodates deeper workpiece access

Compatibility

Designed as a standard chucking reamer for use in lathes, drill presses, and machining centers equipped with a compatible straight-shank chuck or holder accepting a 0.9240-inch diameter tool.

Installation Notes

Installation is performed by qualified machinists. Secure the straight-cylindrical shank firmly in the chuck before operation and confirm runout is within acceptable limits before cutting. Power down all equipment and lock out energy sources before changing or inspecting tooling. Always apply appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
