Hertel 72027006 Chucking Reamer 0.270in Hss Straight Flute

Product Description

The HERTEL 72027006 is a straight-flute chucking reamer designed for precision hole finishing in metal machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore sizing and surface quality in ferrous and non-ferrous materials. The reamer measures 0.2700 inches in diameter with a 6-inch overall length and a 1.5-inch flute length. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. With 6 flutes and right-hand cutting direction, this tool produces accurate, smooth bores suited to close-tolerance work in production and job-shop environments.

This chucking reamer is intended for machine tool use — lathes, drill presses, CNC machining centers, and similar setups where a rotating or stationary reaming operation is required. It is sized in the 0.25 to 0.30-inch decimal inch range, making it appropriate for finishing drilled or bored holes to a 0.2700-inch nominal diameter. Machinists, tool-and-die makers, and CNC operators will find this reamer suitable for general production work requiring repeatable hole geometry and finish quality.

Key Features

• 0.2700-inch diameter for precise hole sizing in the quarter-inch range
• High-speed steel (HSS) construction provides durability across a range of work materials
• Bright, uncoated finish for general-purpose machining without coating-related dimensional offset
• 6 straight flutes with right-hand cutting direction for smooth, even material removal
• Straight-cylindrical shank seats securely in standard drill chucks and collet systems
• 6-inch overall length accommodates typical machine tool reach requirements

Compatibility

Designed as a standard chucking reamer for use in machine tools accepting a straight-cylindrical shank; compatible with drill chucks, ER collets, and similar workholding systems sized for the shank diameter.

Installation Notes

Chucking reamers are installed and operated by machinists using lathes, drill presses, or CNC machining centers. Ensure the workpiece is securely fixtured and the spindle is stopped completely before inserting or removing the tool from the chuck or collet. Use appropriate cutting fluid for the work material to extend tool life and improve surface finish. Do not use a chucking reamer as a hand reamer or apply side loads that could deflect the tool and compromise bore accuracy.
