Hertel 72034515 Chucking Reamer 0.4510 in Hss 6 Flute

Product Description

The HERTEL 72034515 is a straight-flute chucking reamer designed for precision hole finishing in machining operations. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in a wide range of materials. The reamer measures 0.4510 inches in diameter with a 7-inch overall length and a 1.75-inch flute length. The straight-cylindrical shank makes it compatible with standard drill chucks and collet holders. Right-hand cutting direction suits conventional machine spindle rotation. This tool is typically installed by machinists and tool-and-die professionals on drill presses, lathes, and milling machines requiring tight-tolerance bore finishing.

This chucking reamer is suited for production and maintenance machining environments where final bore sizing demands close tolerances. It falls within the 0.4000 to 0.4999 inch reamer diameter range, making it appropriate for finishing holes in that class of work. Common applications include reaming pre-drilled holes in metal components to achieve a smooth, accurate fit for pins, shafts, or bearings. The 6-flute design provides improved surface finish and more stable cutting action compared to fewer-flute alternatives.

Key Features

• 0.4510-inch diameter for precise hole finishing within the 0.4000 to 0.4999 inch diameter class
• High-speed steel (HSS) construction provides durability across a broad range of workpiece materials
• 6-flute straight configuration delivers consistent surface finish and stable chip evacuation
• Bright, uncoated finish suitable for general-purpose machining without added coating cost
• Straight-cylindrical shank for secure, repeatable seating in drill chucks and collet holders
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and milling machines equipped with standard drill chucks or collet holders accepting a straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming procedures and machine tool operation. Ensure the machine spindle is fully stopped and the workpiece is securely fixtured before mounting or removing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Do not exceed the recommended feed and speed parameters for HSS tooling in the material being machined.
