Hertel 72021652 Chucking Reamer 0.2165 in Hss 6 Flute

Product Description

The HERTEL 72021652 is a straight-flute chucking reamer designed for precision hole finishing in metalworking and machining applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurately sized holes to a 0.2165-inch diameter. It features a straight-cylindrical shank for secure chuck holding, six right-hand cutting flutes for smooth material removal, and an overall length of 5 inches with a 1.25-inch flute length. Machinists and tool-and-die professionals install this reamer in drill presses, lathes, and machining centers where close-tolerance bore finishing is required.

This chucking reamer is suited for general-purpose reaming operations on ferrous and non-ferrous metals in machine shop, maintenance, and production environments. It falls within the 0.2000 to 0.2499-inch reamer diameter range, making it appropriate for finish-reaming holes in the lower quarter-inch size class. Typical applications include bearing seat finishing, dowel hole sizing, and precision fit preparation where drilled holes require cleanup and final sizing to tight tolerances.

Key Features

• 0.2165-inch cutting diameter for precise bore finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Six straight flutes with right-hand cutting direction for smooth, chatter-resistant operation
• Bright, uncoated finish suitable for use with cutting fluids
• Straight-cylindrical shank for standard three-jaw or collet chuck mounting
• 5-inch overall length with 1.25-inch flute length for access in typical machine setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill press chucks, lathe tailstock chucks, and collet-style toolholders accepting a straight-cylindrical shank in the appropriate diameter range.

Installation Notes

Installation is performed by qualified machinists following standard machine tool safety procedures. Always power down and lock out the machine before mounting or removing the reamer from the chuck. Secure the straight-cylindrical shank firmly in a matched chuck or collet before operation, and apply an appropriate cutting fluid to extend tool life and improve finish quality. Do not exceed the recommended feed rate or spindle speed for the workpiece material and reamer diameter.
