Hertel 72022759 Chucking Reamer 0.2275 in Hss Straight Flute

Product Description

The HERTEL 72022759 is a straight-flute chucking reamer designed to bring bored or drilled holes to precise final diameter in metal machining applications. Ground from high-speed steel (HSS) with a bright, uncoated finish, this reamer measures 0.2275 inches in diameter and cuts right-hand with six straight flutes. The 6-inch overall length and 1.5-inch flute length make it well suited for through-holes and moderate-depth blind holes in a standard drill press, turret lathe, or CNC machining center. Machinists and tool-and-die professionals reach for this size when finishing holes that fall in the 0.2000 to 0.2499 inch diameter range.

This chucking reamer fits production and job-shop environments where repeatable hole tolerances are required. The straight-cylindrical shank seats directly in a collet, drill chuck, or floating reamer holder. Typical applications include finishing drilled holes in ferrous and non-ferrous workpieces where surface finish and dimensional accuracy are critical. Its compact 0.15-pound weight makes it easy to handle in a toolroom or on a production floor.

Key Features

• 0.2275-inch finished-hole diameter for precision sizing in the 0.2000 to 0.2499 inch range
• Six straight flutes for smooth, consistent cutting action and easy chip evacuation
• Right-hand cutting direction compatible with standard spindle rotation
• High-speed steel construction provides good wear resistance across a broad range of workpiece materials
• Bright, uncoated finish allows visual inspection of the cutting edges before and after use
• Straight-cylindrical shank seats securely in collets, drill chucks, and floating holders

Compatibility

Designed as an OEM-style replacement or standard chucking reamer for use in drill presses, lathes, and CNC machining centers that accept a straight-cylindrical shank reamer in the 0.2000 to 0.2499 inch diameter range.

Installation Notes

Chucking reamers are installed by machinists and toolroom professionals. Before mounting, ensure the spindle is fully stopped and the machine is in a safe, locked-out state per applicable OSHA lockout/tagout procedures. Seat the straight-cylindrical shank fully into the holder and verify runout before cutting. Use appropriate cutting fluid for the workpiece material to prolong edge life and improve surface finish.
