Hertel 72025950 Chucking Reamer 0.2595 in Hss Straight Flute

Product Description

The HERTEL 72025950 is a high-speed steel (HSS) chucking reamer designed to bring bored or drilled holes to precise finished dimensions. Carrying a 0.2595 inch cutting diameter, this reamer features a straight-cylindrical shank for secure chuck mounting and six straight flutes with a right-hand cutting direction. The bright, uncoated finish suits general-purpose ferrous and non-ferrous materials. Overall length is 6 inches with a 1.5 inch flute length. At 0.15 pounds, it is a compact, lightweight tool appropriate for production and maintenance drilling operations performed by machinists and toolroom technicians.

This chucking reamer is suited for finishing holes in the 0.2500 to 0.2999 inch diameter range. It is used in manual drill presses, CNC machining centers, lathes, and other rotating-spindle equipment where close-tolerance hole finishing is required. Typical applications include precision component manufacturing, fixture and die work, and maintenance repair operations across metalworking shops. The straight-cylindrical shank allows mounting in standard drill chucks or collet holders without special tooling adapters.

Installation Notes

Chucking reamers are installed and serviced by machinists and toolroom technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in the chuck or collet to minimize runout before cutting. Apply appropriate cutting fluid for the work material to extend tool life and improve surface finish quality.
