Hertel 45675980 Chucking Reamer 0.307 in Solid Carbide

Product Description

The HERTEL 45675980 is a solid carbide chucking reamer designed for precision hole finishing in machining operations. Built with 6 straight flutes and a right-hand cutting direction, it delivers consistent dimensional accuracy when sizing drilled or bored holes to a final diameter of 0.307 inches. The straight shank is compatible with standard drill chucks and collet holders. At 3.25 inches overall length with a 1.125-inch flute length, this reamer is suited for shallow-to-moderate depth finishing passes. The bright polished finish reduces built-up edge and supports clean chip evacuation in ferrous and non-ferrous materials.

This chucking reamer is intended for use in CNC machining centers, manual mills, and drill presses where tight hole tolerances are required. It is commonly applied in production environments for reaming holes in steel, cast iron, aluminum, and similar materials where a precise 0.307-inch finished bore is specified. The solid carbide construction makes it appropriate for higher-speed applications and harder workpiece materials where high-speed steel tooling would wear prematurely.

Key Features

• 0.307-inch finished diameter in the 0.3000 to 0.3499 inch diameter range
• Solid carbide construction for rigidity and wear resistance
• 6 straight flutes with right-hand cutting direction
• Bright polished finish reduces friction and supports clean chip flow
• Straight shank fits standard chucks and collet systems
• 3.25-inch overall length with 1.125-inch flute length for controlled depth passes

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard drill chucks and collet holders on CNC and manual machining equipment requiring a 0.307-inch finished bore diameter.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations. Secure the shank firmly in a drill chuck or collet before operation and verify runout is within acceptable limits to maintain hole tolerance. Always reduce spindle speed relative to drilling and apply appropriate cutting fluid for the workpiece material. Never use a reamer to remove excessive stock — pre-drill or bore the hole to within a few thousandths of final size before reaming.
