Hertel 72034648 Chucking Reamer 0.4640 in Hss 6 Flute

Product Description

The HERTEL 72034648 is a straight-flute chucking reamer designed for precision hole finishing in metal and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore sizing across a range of drilling and machining operations. The reamer measures 0.4640 inches in diameter with a 7-inch overall length and a 1.75-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks or collets. With six right-hand cutting flutes, it produces smooth, accurate finishes in through-holes and blind bores. Machinists and toolroom technicians are the primary users.

This chucking reamer is suited for machine shop and production environments where close-tolerance hole finishing is required. It fits standard vertical mills, drill presses, lathes, and CNC machining centers equipped with compatible chuck or collet tooling. The 0.4640-inch diameter falls within the 0.4000 to 0.4999-inch decimal range, making it appropriate for applications demanding precise bore sizing in that range. It is sold individually with a minimum order quantity of one.

Key Features

• High-speed steel (HSS) construction provides hardness and wear resistance for ferrous and non-ferrous materials
• Six straight right-hand cutting flutes for smooth, consistent bore finishing
• Bright, uncoated finish suitable for general-purpose machining applications
• Straight-cylindrical shank for secure seating in drill chucks or collets
• 7-inch overall length with 1.75-inch flute length for controlled cutting depth

Compatibility

Designed as a general-purpose chucking reamer for use in standard machine tool setups accepting a straight-cylindrical shank in the corresponding diameter range.

Installation Notes

Installation of this reamer should be performed by a qualified machinist following standard toolroom procedures. Secure the straight-cylindrical shank fully into a properly sized chuck or collet before operation, and verify runout before cutting. Power down and lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
