Hertel 2410199 Chucking Reamer 19/64 in Hss 6 Flute

Product Description

The HERTEL 2410199 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled holes to a precise 19/64-inch (0.2969 decimal inch) diameter. Built with 6 spiral flutes and a right-hand cutting direction, it delivers smooth, accurate bore finishing in a wide range of metalworking applications. The straight-cylindrical shank seats directly in standard drill chucks or collets. Overall length is 6 inches with a 1.5-inch flute length, and the tool arrives in a bright, uncoated finish ready for use. Machinists and tool-and-die professionals rely on this style of reamer to hold tight hole tolerances in production and maintenance machining environments.

This chucking reamer is suited for use on lathes, drill presses, CNC machining centers, and manual mills where a finish-reamed hole is required. The 19/64-inch diameter falls within the 0.2500 to 0.2999 decimal-inch reamer diameter range, making it a standard selection for close-tolerance hole finishing in steel, cast iron, aluminum, and similar machinable materials. Left-hand spiral flutes help pull chips out of the hole during right-hand cutting, reducing chatter and improving surface finish in through-hole and blind-hole operations.

Key Features

• HSS construction provides toughness and wear resistance for general-purpose metalworking
• 6 left-hand spiral flutes with right-hand cutting direction for smooth chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Bright, uncoated finish — ready to use as-delivered or receptive to aftermarket coatings
• 0.2969 decimal-inch diameter for precise 19/64-inch hole finishing
• 6-inch overall length with 1.5-inch flute length for reach in standard setups

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped to accept a straight-cylindrical shank reamer in the 19/64-inch diameter range.

Installation Notes

This reamer is installed by a machinist or tool-and-die professional into a drill chuck, collet, or floating reamer holder on a lathe, drill press, or machining center. Always ensure the hole has been pre-drilled to the correct undersize before reaming, and secure the workpiece fully before beginning the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the reamer for chipping or wear before each use.
