Hertel 72034150 Chucking Reamer 0.415 in Hss 6 Flute

Product Description

The HERTEL 72034150 is a straight-flute chucking reamer designed for precision hole finishing in machine shop and production environments. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing at 0.4150 inches in diameter over a 7-inch overall length. The 1-3/4-inch flute length provides effective cutting engagement, while the straight-cylindrical shank allows secure mounting in standard drill chucks, collets, and floating reamer holders. Machinists and tool-and-die professionals rely on this type of reamer to bring drilled or bored holes to final tolerance with consistent results.

This chucking reamer is suited for general-purpose reaming operations on ferrous and non-ferrous workpieces in manual and CNC machine tools including lathes, mills, and drill presses. The right-hand cutting direction and straight flute geometry make it appropriate for through-holes and blind holes where chip control is manageable and surface finish consistency is a priority. It is a direct run-to-size tool, not an over- or under-size reamer, and is not intended for dowel-pin applications.

Key Features

• 0.4150-inch reamer diameter for precise hole sizing to tolerance
• High-speed steel (HSS) construction provides durability across a wide range of work materials
• Bright, uncoated finish — ready for use as-is or compatible with shop-applied cutting fluid
• Straight-cylindrical shank fits standard chucks and collets without adapters
• 6-flute, right-hand cutting geometry for smooth, consistent surface finish
• 7-inch overall length accommodates standard machine spindle reach

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with drill chucks, ER collets, or floating reamer holders accepting a straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists following standard machine shop safety practices. Secure the shank fully in the chuck or collet and verify runout before cutting. Power down and lock out the machine before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
