Hertel 72022502 Chucking Reamer 0.2250 in Hss 6 Flute

Product Description

The HERTEL 72022502 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.2250-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing and smooth bore finishes in production and maintenance machining environments. The straight-cylindrical shank seats securely in a drill chuck or collet chuck, and the six-flute geometry distributes cutting load evenly for consistent results. At 6 inches overall length with a 1.5-inch flute length, this reamer is suited for through-holes and shallow blind holes in a range of ferrous and non-ferrous materials.

This chucking reamer is used in machine shop, toolroom, and MRO applications where a drilled hole must be brought to a close-tolerance final diameter. It is compatible with standard drill presses, lathes, and CNC machining centers equipped with a chuck or straight-shank collet. Right-hand cutting direction makes it suitable for conventional clockwise-spindle operation. Typical applications include precision hole finishing in steel, cast iron, aluminum, brass, and similar machinable materials where reamed surface finish and dimensional accuracy are required.

Key Features

• 0.2250-inch reamer diameter for precise hole sizing within the 0.2000 to 0.2499-inch range
• Six straight flutes distribute cutting forces evenly and support consistent finish quality
• High-speed steel (HSS) construction provides good wear resistance across common machinable materials
• Bright, uncoated finish — no coating buildup concerns when using cutting fluids
• Straight-cylindrical shank for secure, repeatable chuck or collet mounting
• Right-hand cutting direction compatible with standard clockwise spindle machines

Compatibility

Designed as an OEM-style chucking reamer for use in any drill press, lathe tailstock, or CNC machining center that accepts a straight-cylindrical shank tool. No specific model compatibility data was provided in the product source information.

Installation Notes

Installation and operation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer from the chuck or collet. Use an appropriate cutting fluid or lubricant for the workpiece material to maximize tool life and bore finish. Never attempt to use a chucking reamer as a hand reamer or apply side-loading force during operation.
