Hertel 2292126 Chucking Reamer Letter L Hss 6 Flute

Product Description

The HERTEL 2292126 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 produces accurate, smooth bores to Letter L size, which corresponds to a decimal diameter of 0.2900 inches. The straight-cylindrical shank allows secure seating in standard drill chucks or collet holders. With six flutes and right-hand cutting action, this reamer removes material evenly and maintains tight tolerances in through-holes and blind bores. Machinists and tool-and-die professionals use this reamer in manual or CNC machine setups where a controlled final bore diameter is required.

This chucking reamer is suited for production and jobsite machining work where consistent bore finish and size accuracy are critical. It fits residential and industrial machine shop environments alike, including applications on drill presses, lathes, and machining centers. The 1.5-inch flute length accommodates typical hole depths encountered in standard workpiece stock. The 6-inch overall length provides adequate clearance from the chuck face to the cutting edge in most setups.

Key Features

• Letter L diameter (0.2900 inches) for precise hole finishing to a specific fractional-range bore
• 6-flute straight configuration for smooth, even material removal and good surface finish
• High-speed steel (HSS) construction for wear resistance across a range of workpiece materials
• Bright, uncoated finish — compatible with a wide variety of cutting fluids
• Straight-cylindrical shank seats securely in standard drill chucks and collet holders
• Right-hand cutting direction for use in conventional machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet holders on drill presses, lathes, and machining centers that accept straight-cylindrical shank tooling.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations. Ensure the machine spindle is fully stopped and the workpiece is securely clamped before tool changes. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Do not use a reamer to remove excessive stock — pre-drill or bore the hole to within standard reaming allowance before reaming to final size.
