Hertel 72034796 Chucking Reamer 0.4790 in Hss 6 Flute

Product Description

The HERTEL 72034796 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.4790-inch diameter. With an overall length of 8 inches and a 2-inch straight flute length, this right-hand cutting reamer delivers accurate sizing and smooth surface finishes in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in drill chucks and collet holders. Supplied in a bright, uncoated finish, the 6-flute geometry distributes cutting load evenly and removes chips efficiently. This tool is suited for machinists, tool-and-die tradespeople, and maintenance technicians working in shop or field environments.

The 72034796 is applied in machine shop operations where a drilled hole must be brought to close-tolerance size and finish. Typical applications include reaming clearance and bearing bores in steel, cast iron, aluminum, and brass components. The straight flute design performs reliably in through-hole applications and short blind-hole work. The straight-cylindrical shank allows use in a standard drill press, milling machine, or CNC machining center with an appropriate chuck or collet. This reamer falls within the 0.4000 to 0.4999 decimal-inch diameter range, making it a direct selection for that size class.

Key Features

• 0.4790-inch finished diameter with 6 straight flutes for even load distribution and consistent hole sizing
• HSS construction provides toughness and wear resistance across a wide range of workpiece materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank compatible with drill chucks and collet systems
• Right-hand cutting direction for standard clockwise spindle operation
• 8-inch overall length provides clearance for deep-reach applications while maintaining rigidity

Compatibility

Designed as a standard chucking reamer for use in drill presses, manual mills, and CNC machining centers equipped with drill chucks or straight-shank collet holders accepting a 0.4790-inch-diameter tool body.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or skilled tradesperson familiar with rotating cutting tools. Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout before taking a finishing pass. Always apply appropriate cutting fluid for the workpiece material to extend tool life and achieve the intended surface finish. Power down and de-energize the machine spindle completely before inserting or removing the reamer from the holder.
