Hertel 72296817 Chucking Reamer 0.4995 in Hss 6 Flute

Product Description

The HERTEL 72296817 is a straight-cylindrical shank chucking reamer designed to finish-ream holes to a precise diameter of 0.4995 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore quality in metalworking applications. The tool features 6 spiral flutes with right-hand cutting and right-hand spiral direction, producing a clean, accurate finish in drilled or bored holes. With an overall length of 6 inches and a flute length of 2 inches, it fits standard drill press and CNC lathe chuck setups commonly used by machinists and tool-and-die professionals.

This chucking reamer is suited for precision hole finishing in ferrous and non-ferrous metals in both production and jobshop environments. It is used wherever a drilled hole must be brought to a close-tolerance final diameter. The straight-cylindrical shank mounts directly in a drill chuck, collet, or floating reamer holder, making it compatible with drill presses, milling machines, lathes, and CNC machining centers. The 0.4995-inch diameter makes it a common choice for dowel pin fits and close-clearance shaft bores requiring dimensional accuracy.

Key Features

• Precision ground to 0.4995 inches diameter for tight-tolerance hole finishing
• 6 spiral flutes with right-hand cut and right-hand spiral for smooth chip evacuation
• HSS construction provides good wear resistance across a range of workpiece materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank for direct chucking in standard holders
• 6-inch overall length with 2-inch flute length accommodates typical through-hole and blind-hole depths

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with a drill chuck, collet, or floating holder accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists. Ensure the workpiece is securely fixtured and the spindle is at an appropriate speed and feed rate for reaming before engaging the tool. Always apply cutting fluid to extend tool life and improve surface finish. Inspect the shank and chuck jaws for runout before use, as excessive runout will degrade hole tolerance and tool life.
