Hertel 72029200 Chucking Reamer 0.2920 in Hss 6 Flute

Product Description

The HERTEL 72029200 is a straight-flute chucking reamer designed for precision hole finishing in metal working applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent sizing and smooth bore surfaces in drilled or bored holes. It measures 0.2920 inches in diameter with a 6-inch overall length and a 1.5-inch flute length. The straight-cylindrical shank allows secure seating in standard drill chucks or collet holders. With 6 flutes and right-hand cutting direction, it provides accurate, chatter-free reaming on manual machines and CNC equipment alike. Licensed machinists and tool-and-die professionals are the primary installers of this tool.

This reamer falls in the 0.2500 to 0.2999 inch diameter range and is suited for finishing through-holes and blind holes in ferrous and non-ferrous stock. Typical applications include production machining, job-shop work, and maintenance repair operations where hole tolerance and finish are critical. The 6-inch OAL provides sufficient reach for most standard workpiece thicknesses encountered in general machining setups.

Key Features

• 0.2920 inch reamer diameter for precise hole finishing within the 0.2500 to 0.2999 inch range
• HSS construction provides toughness and wear resistance across a range of workpiece materials
• 6-flute straight configuration for smooth cutting action and consistent finish quality
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright uncoated finish suitable for use with cutting fluids in general-purpose applications
• Straight-cylindrical shank fits standard chucks and collet systems without modification

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for machines accepting a straight-cylindrical shank tool with a 0.2920 inch cutting diameter.

Installation Notes

This tool is installed by machinists in drill presses, lathes, CNC machining centers, or manual mills using a standard chuck or collet holder sized for the straight-cylindrical shank. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Always use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not exceed the recommended feed and speed parameters for HSS tooling in the material being machined.
