Hertel 72295215 Chucking Reamer 21/64 in Hss 6 Flute

Product Description

The HERTEL 72295215 is a high-speed steel (HSS) chucking reamer designed to bring bored or drilled holes to a precise finished diameter. With a nominal diameter of 21/64 inches (0.3281 decimal inches), a 1-1/2 inch flute length, and a 4-5/8 inch overall length, this reamer is built for machine use in a drill press, lathe, or CNC setup. The six-flute spiral configuration with a right-hand cutting direction delivers smooth stock removal and a consistent finish. The straight-cylindrical shank seats securely in a standard chuck. Machinists, tool-and-die workers, and maintenance technicians use this type of reamer wherever tight hole tolerances and smooth bore surfaces are required.

This chucking reamer is suited for through-hole and blind-hole finishing operations in metalworking applications across job shops, production floors, and maintenance facilities. The bright uncoated HSS construction performs well in a range of ferrous and non-ferrous materials at standard cutting speeds. It is a solid choice for finishing holes in fixtures, jigs, and general machine components where dimensional accuracy is critical. The straight-cylindrical shank makes it compatible with standard drill chucks and collet holders without requiring special toolholding.

Key Features

• 21/64 inch nominal diameter (0.3281 decimal inches) for precise hole finishing
• Six spiral flutes with right-hand cutting direction for smooth material removal
• HSS construction provides durability across ferrous and non-ferrous workpiece materials
• Bright uncoated finish suitable for general-purpose machine reaming applications
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

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

Installation Notes

Chucking reamers are installed by machinists and tooling technicians into a powered machine spindle — never used freehand. Secure the straight shank firmly in a drill chuck or collet before operation and verify runout before cutting. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Always bring the machine to a full stop before removing or inspecting the tool.
