Hertel 72029309 Chucking Reamer 0.2930 in Hss Straight Flute

Product Description

The HERTEL 72029309 is a straight-flute chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing and smooth bore surfaces in a range of ferrous and non-ferrous materials. The reamer measures 0.2930 inches in diameter with a 6-inch overall length and a 1.5-inch flute length. Its straight-cylindrical shank allows secure seating in standard drill chucks or collets. With 6 flutes and right-hand cutting direction, it produces clean, consistent finishes. Machinists and toolroom professionals install this type of reamer in drill presses, lathes, and CNC machining centers.

This chucking reamer is suited for finishing drilled or bored holes to close tolerances in production and repair machining environments. The 0.2930-inch diameter falls within the 0.2500 to 0.2999 inch reamer diameter range, making it appropriate for applications requiring precise hole sizing in that class. It is not an over/under size or dowel pin reamer. Typical use cases include through-hole and blind-hole finishing in job shops, maintenance facilities, and production machining operations where dimensional accuracy and surface finish are critical.

Key Features

• 0.2930 inch reamer diameter for precise hole finishing to close tolerances
• 6-flute straight configuration promotes smooth cutting action and consistent finish
• High-speed steel (HSS) construction provides durability across a range of work materials
• Bright, uncoated finish suitable for general-purpose machining applications
• Straight-cylindrical shank seats securely in standard drill chucks and collets
• Right-hand cutting direction compatible with conventional machine spindle rotation

Compatibility

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

Installation Notes

Chucking reamers are installed and operated by machinists and toolroom technicians. Power down and de-energize the machine spindle completely before mounting or removing the tool. Ensure the shank is clean and fully seated in the chuck or collet before tightening. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
