Hertel 72033269 Chucking Reamer 0.3260 in Hss Straight

Product Description

The HERTEL 72033269 is a straight-flute chucking reamer designed to finish-ream drilled holes to precise diameter in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing performance across a range of ferrous and non-ferrous materials. The reamer measures 0.3260 inches in diameter, runs 6 inches in overall length, and features a 1.5-inch flute length with a straight-cylindrical shank for secure chuck retention. With 6 right-hand cutting flutes, it removes material evenly and produces a smooth bore finish suited to close-tolerance work.

This chucking reamer is intended for use in machine shop, toolroom, and production environments where hole diameter must be held to tight tolerances after drilling. The straight-cylindrical shank seats directly in a drill chuck, collet, or floating reamer holder on a drill press, lathe, or CNC machining center. It is appropriate for applications in general machining, maintenance repair, and fabrication where a 0.3260-inch finished bore diameter is required. Licensed machinists and skilled trade professionals are the primary installers of this tooling.

Key Features

• 0.3260-inch reamer diameter within the 0.3000 to 0.3499-inch decimal inch range
• High-speed steel (HSS) construction for durability across general-purpose machining applications
• 6 straight right-hand cutting flutes for smooth, even material removal
• Bright, uncoated finish — compatible with cutting fluids for extended tool life
• Straight-cylindrical shank fits standard drill chucks, collets, and floating holders
• 6-inch overall length with 1.5-inch flute length for controlled reaming depth

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a standard drill chuck or collet capable of holding a straight-cylindrical shank at the specified diameter.

Installation Notes

Always power down and lock out the machine spindle before mounting or removing tooling. Secure the straight-cylindrical shank firmly in a drill chuck, collet, or floating reamer holder to minimize runout. Use an appropriate cutting fluid for the workpiece material to reduce heat buildup and extend tool life. Never run a reamer in reverse, as reverse rotation will dull the cutting edges rapidly.
