Hertel 45675998 Chucking Reamer 0.3080 in Solid Carbide

Product Description

The HERTEL 45675998 is a solid carbide chucking reamer designed for precision hole finishing in machining operations. With a reamer diameter of 0.3080 inches and a 1-1/8 inch straight flute length, it delivers accurate, repeatable bore sizing in a single pass. The straight-cylindrical shank makes it compatible with standard chuck holders on mills, lathes, and drill presses. At 3-1/4 inches overall length, it suits typical through-hole and blind-hole applications in production and toolroom environments. Machinists and CNC operators in metalworking, mold-making, and general precision machining are the primary users of this tool.

This chucking reamer is suited for finishing holes in the 0.3000 to 0.3499 inch diameter range. It is appropriate for use in ferrous and non-ferrous metals where tight bore tolerances are required. The right-hand cutting direction and six-flute straight geometry make it a solid choice for reaming pre-drilled holes in production runs or one-off precision work. The bright, uncoated finish is standard for general-purpose solid carbide reamers used without specific coating requirements.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.3080 inch diameter delivers accurate finished bore sizing
• Six straight flutes provide smooth cutting action and consistent chip evacuation
• Right-hand cutting direction compatible with standard spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright, uncoated finish suitable for general-purpose metalworking applications

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, manual mills, lathes, and drill presses equipped with a chuck or collet capable of holding a straight-cylindrical shank in the 0.3080 inch diameter class.

Installation Notes

Chucking reamers should be installed by qualified machinists following proper toolholding procedures for the machine in use. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the straight-cylindrical shank firmly in a collet or drill chuck to minimize runout, which directly affects finished bore accuracy. Always ream a pre-drilled or bored hole that is appropriately sized to the recommended stock allowance for the reamer diameter.
