Hertel 72022650 Chucking Reamer 0.2265 in Hss 6 Flute

Product Description

The HERTEL 72022650 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate bore diameters in a range of workpiece materials. The reamer measures 0.2265 inches in diameter with a 6-inch overall length and a 1.5-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. Six right-hand cutting flutes provide smooth material removal and consistent surface finish. At 0.15 pounds, it is lightweight and easy to handle during setup. This tool is intended for use by machinists and tool-and-die professionals on lathes, drill presses, and CNC machining centers.

This chucking reamer is suited for through-hole and blind-hole reaming operations where tight diameter tolerances are required. The 0.2265-inch diameter falls within the 0.2000 to 0.2499-inch decimal inch range, making it a common choice for finishing drilled holes prior to press-fit or close-clearance assembly. Typical applications include production machining, tool room work, and maintenance repair operations where hole geometry and surface finish are critical to part function.

Key Features

• 0.2265-inch reamer diameter for precision hole finishing
• HSS construction provides durability across a wide range of workpiece materials
• Six straight flutes with right-hand cutting direction for smooth, controlled stock removal
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank compatible with standard chucks and collet systems
• 6-inch overall length with 1.5-inch flute length for reach and rigidity balance

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers that accept straight-cylindrical shank tooling in the applicable diameter range.

Installation Notes

Chucking reamers are installed by machinists using a drill chuck or collet holder sized for the straight-cylindrical shank. Ensure the workpiece is securely fixtured and the spindle is properly aligned before beginning the reaming pass. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never reverse a reamer under power, as this will damage the cutting edges.
