Hertel 2350486 Chucking Reamer 3/4 in Hss 8 Flute

Product Description

The HERTEL 2350486 is a straight-shank chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in a 0.7500 inch diameter bore. The 8-flute spiral configuration with right-hand cutting direction provides smooth material removal and a consistent surface finish. At 9.5 inches overall length with a 2.5 inch flute length, this reamer is suited for general machining applications where tight tolerances are required. It is installed in standard drill chucks or collet holders on mills, lathes, and drill presses by machinists and toolroom professionals.

This chucking reamer is intended for finishing pre-drilled or bored holes to a precise 0.7500 inch diameter. It is well-suited for job shop, production machining, and maintenance repair operations across industries that require tight-tolerance hole sizing in steel, cast iron, aluminum, and similar machinable materials. The straight-cylindrical shank seats securely in standard drill chucks and collet systems without the need for special adapters.

Key Features

• 0.7500 inch finished bore diameter for precise hole sizing
• 8-flute spiral design for smooth cutting action and improved surface finish
• Right-hand spiral and right-hand cutting direction for standard machine operation
• HSS construction provides toughness and wear resistance in general-purpose machining
• Bright uncoated finish suitable for use with a wide range of cutting fluids
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters

Compatibility

Designed as a standard chucking reamer for use in drill chucks, ER collet holders, and similar straight-shank toolholding systems on CNC mills, manual lathes, drill presses, and machining centers capable of accepting a 0.7500 inch diameter straight shank tool.

Installation Notes

Installation is performed by machinists using standard toolholding equipment. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. The workpiece hole should be pre-drilled or bored to the appropriate undersize before reaming to achieve the specified finished diameter. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
