Hertel 72037864 Chucking Reamer 0.7860 in Hss 8 Flute

Product Description

The HERTEL 72037864 is a high-speed steel (HSS) chucking reamer designed for finishing drilled or bored holes to tight dimensional tolerances. With a reamer diameter of 0.7860 inches, an overall length of 9.5 inches, and a flute length of 2.5 inches, this tool delivers consistent hole sizing in a wide range of machining applications. The bright, uncoated HSS construction provides reliable performance across common workpiece materials. Eight straight flutes and a right-hand cutting direction make it well-suited for use in manual or CNC drilling setups where precision bore finishing is required.

This chucking reamer is used in machine shops, production environments, and maintenance facilities wherever accurate hole finishing is needed. The straight-cylindrical shank allows it to seat securely in standard drill chucks and collet holders. It is appropriate for applications in the 0.7000 to 0.9999 inch reamer diameter range and handles typical bore finishing work on ferrous and non-ferrous materials. Machinists and toolroom technicians install this reamer for final-pass operations that bring hole diameter to specification after rough drilling or boring.

Key Features

• 0.7860 inch reamer diameter for precision bore finishing
• HSS construction — bright, uncoated finish suitable for a broad range of materials
• 8 straight flutes for smooth, consistent material removal
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank seats in standard drill chucks and collets
• 9.5 inch overall length with a 2.5 inch flute length for reach in typical setups

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a standard chuck or collet capable of accepting a straight-cylindrical shank in this diameter range.

Installation Notes

Chucking reamers are installed and used by machinists and toolroom technicians. Ensure the machine spindle is fully stopped and the tool is securely clamped in the chuck or collet before starting. Reamers should be run at lower RPM than drilling operations and with appropriate cutting fluid to extend tool life and maintain hole finish quality. Never run a reamer in reverse, as this will damage the cutting edges.
