Hertel 75977751 Chucking Reamer 0.9970 in Hss 8 Flute

Product Description

The HERTEL 75977751 is a chucking reamer designed for precision hole finishing in machine tool applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing of drilled or bored holes to tight tolerances. The reamer measures 0.9970 inches in diameter with an overall length of 10-1/2 inches and a flute length of 2-3/4 inches. Eight straight flutes and a right-hand cutting direction make this tool well suited for use in drill presses, lathes, and CNC machining centers. It is installed by machinists and tool and die professionals requiring consistent bore diameter control.

This chucking reamer is intended for finishing holes in the 0.7000 to 0.9999 inch diameter range, with this specific unit ground to 0.9970 inches. The straight-cylindrical shank allows secure mounting in standard machine chucks or collets. It is commonly used in job shops, production machining environments, and maintenance repair operations where precise bore sizing in metal workpieces is required. The right-hand cutting direction is compatible with standard machine spindle rotation.

Compatibility

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

Installation Notes

This reamer is installed by machinists and tooling professionals. Always secure the straight-cylindrical shank firmly in a compatible chuck or collet before operation, and confirm the machine spindle is set to right-hand rotation. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Inspect the reamer for wear or damage before each use to maintain dimensional accuracy.
