Hertel 2410280 Chucking Reamer 7/16 Inch Hss

Product Description

The HERTEL 2410280 is a high-speed steel (HSS) chucking reamer designed to produce precise, finished bores in metal workpieces. With a 7/16 inch (0.4375 inch) reamer diameter, 6 spiral flutes with a left-hand spiral direction, and right-hand cutting action, this tool delivers smooth, accurate hole finishing in a range of ferrous and non-ferrous materials. The bright, uncoated finish suits general-purpose reaming applications where specialized coatings are not required. The straight-cylindrical shank allows direct mounting in standard drill chucks, collet chucks, and floating holders. Machinists and tool-and-die professionals install this reamer in CNC and manual machining operations requiring tight dimensional control.

This chucking reamer is suited for general machine shop use, production floor environments, and toolroom operations. It is applied to through-holes and blind holes where a finished bore is required after drilling. The 7 inch overall length (OAL) and 1-3/4 inch flute length make it appropriate for moderate-depth bore finishing in block, plate, and shaft workpieces. No special setup is required beyond a properly aligned spindle and appropriate cutting fluid for the workpiece material.

Key Features

• 7/16 inch (0.4375 inch) reamer diameter for precise bore sizing
• 6 spiral flutes with left-hand spiral and right-hand cutting for chatter reduction
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish for general-purpose reaming without added coating cost
• Straight-cylindrical shank for compatibility with standard chucks and holders
• 7 inch OAL with 1-3/4 inch flute length for moderate-depth bore applications

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks, collet chucks, and floating reamer holders accepting a straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations. Ensure the spindle is stopped and the machine is powered down before mounting or removing the reamer from its holder. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Never force the reamer into a hole smaller than the specified entry diameter, as this may damage the flutes or compromise bore accuracy.
