Hertel 72034358 Chucking Reamer 0.4350 in Hss 6 Flute

Product Description

The HERTEL 72034358 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.4350-inch diameter. Constructed from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in general-purpose machining operations. The reamer features a straight-cylindrical shank for secure chuck mounting and six right-hand cutting flutes that produce smooth, accurate bores. With an overall length of 7 inches and a flute length of 1.75 inches, it is sized for use in drill presses, lathes, and CNC machining centers where tight hole tolerances are required.

This chucking reamer is suited for production and maintenance machining environments where holes require sizing after drilling. It is appropriate for use in metals such as mild steel, aluminum, brass, and similar materials typically encountered in job shop and industrial manufacturing settings. The 0.4350-inch diameter falls within the 0.4000 to 0.4999 inch reamer diameter range, making it a standard selection for precision hole finishing in both manual and automated setups.

Key Features

• 0.4350-inch finished bore diameter for precise hole sizing
• High-speed steel (HSS) construction for durability across common workpiece materials
• Bright, uncoated finish suitable for general-purpose applications
• Six straight flutes with right-hand cutting direction for smooth material removal
• Straight-cylindrical shank for straightforward chuck or collet mounting
• 7-inch overall length with 1.75-inch flute length for controlled reach and rigidity

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, and CNC machining centers that accept straight-cylindrical shank tooling.

Installation Notes

Installation and operation of this reamer should be performed by qualified machinists familiar with rotating cutting tools. Secure the straight-cylindrical shank firmly in a chuck or collet before use, and ensure the spindle is fully stopped before tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Follow applicable machine guarding and PPE requirements per shop safety standards.
