Hertel 72022056 Chucking Reamer 0.2205 in Hss 6 Flute

Product Description

The HERTEL 72022056 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.2205-inch diameter. With a straight-cylindrical shank, this reamer mounts directly in a drill chuck or collet on a drill press, lathe, or CNC machine. The 6-flute, right-hand cutting geometry distributes cutting load evenly across the flute length of 1.25 inches, producing a smooth, accurate bore surface. Overall length is 5 inches. The bright, uncoated finish is well suited to general-purpose reaming in steel, cast iron, aluminum, and similar materials. Machinists and tool-and-die technicians are the primary installers of this tooling.

This chucking reamer is used in machine shop, maintenance, and production environments where drilled holes require tight-tolerance finishing. Its 0.2205-inch diameter falls within the 0.2000 to 0.2499 inch diameter range, making it a common selection for letter and number drill series hole finishing. Typical applications include bearing seat preparation, dowel pin hole finishing, and close-tolerance hole sizing on ferrous and non-ferrous workpieces. It is intended for use in a powered spindle rather than by hand.

Key Features

• 0.2205-inch finished bore diameter for precise hole sizing
• 6-flute, right-hand straight-flute geometry for smooth, even cutting action
• HSS construction provides good toughness and wear resistance in general-purpose machining
• Straight-cylindrical shank for direct chuck or collet mounting
• Bright, uncoated finish — no coating to add dimensional variance at the cutting edge
• 1.25-inch flute length suitable for shallow to moderate hole depths

Compatibility

Designed as an OEM-style chucking reamer for use in any drill press, lathe tailstock, or CNC spindle equipped with a chuck or collet accepting a straight-cylindrical shank in the corresponding diameter range.

Installation Notes

A licensed machinist or qualified tooling technician should install and operate this reamer. Power down and de-energize the spindle machine fully before changing tooling. Secure the straight shank firmly in a properly sized chuck or collet to prevent runout, which will degrade hole finish and reamer life. Use appropriate cutting fluid for the workpiece material and ensure the reamer is run at the correct speed and feed per standard machining practice for HSS tooling.
