Hertel 2292084 Chucking Reamer Letter H Hss 6 Inches Oal

Product Description

The HERTEL 2292084 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy when enlarging or finishing drilled holes to a tight tolerance. The reamer carries a Letter H designation, corresponding to a decimal diameter of 0.2660 inches, and features 6 straight flutes with right-hand cutting action. Overall length is 6 inches with a 1.5-inch flute length. The straight-cylindrical shank seats directly into a drill chuck or collet for straightforward setup on drill presses, lathes, and CNC machining centers.

This chucking reamer is suited for production and maintenance machining environments where hole size and surface finish are critical. It is commonly used by machinists, tool-and-die workers, and maintenance technicians working in light to medium-duty applications. The 0.2660-inch diameter is appropriate for finishing holes that require close-tolerance fits such as dowel pin bores, bushing bores, and precision assembly clearance holes. It is sold in single-piece quantity with no special packaging required.

Key Features

• Letter H diameter (0.2660 inches) for precise hole finishing within the 0.2500 to 0.2999 inch range
• 6 straight flutes with right-hand cutting direction for smooth, consistent stock removal
• HSS construction provides good wear resistance across a broad range of workpiece materials
• Bright, uncoated finish — no coating buildup concerns when regrinding
• Straight-cylindrical shank compatible with standard drill chucks and collets
• 6-inch overall length with 1.5-inch flute length suits standard chuck reach depths

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank at the 0.2660-inch nominal diameter range.

Installation Notes

Installation and operation should be performed by a qualified machinist or trained technician. Ensure the machine spindle is fully stopped and the chuck or collet is properly tightened before engaging the workpiece. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not run a chucking reamer in reverse, as this will dull the cutting edges.
