Hertel 45676830 Chucking Reamer 0.443 in Solid Carbide

Product Description

The HERTEL 45676830 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. Built with a straight shank and straight flute geometry, this reamer delivers accurate, repeatable hole sizing to a diameter of 0.443 inches. The bright polished finish reduces friction and helps evacuate chips cleanly during cutting. With 6 right-hand cutting flutes and a 1-3/8 inch flute length within a 4 inch overall length, this tool suits CNC machining centers, lathes, and drill press setups where tight tolerances are required. Machinists and tool-and-die professionals are the primary users of this reamer.

This chucking reamer is suited for finishing pre-drilled or bored holes in ferrous and non-ferrous metals where dimensional accuracy and surface finish are critical. The straight shank interfaces directly with drill chucks, collet chucks, or toolholders commonly found on vertical machining centers and engine lathes. It performs well in production and job-shop environments where consistent hole quality is required across multiple workpieces. The solid carbide construction provides rigidity and wear resistance compared to high-speed steel alternatives, making it appropriate for harder workpiece materials and higher-speed cutting operations.

Key Features

• 0.443 inch reamer diameter for precise hole finishing
• Solid carbide construction for rigidity and extended tool life
• 6 right-hand straight flutes for smooth, accurate cutting action
• Bright polished finish reduces friction and aids chip evacuation
• Straight shank compatible with standard drill chucks and collet systems
• 4 inch overall length with 1-3/8 inch flute length for balanced reach and rigidity

Compatibility

Designed as a straight-shank chucking reamer for use in drill chucks, collet chucks, and compatible toolholding systems on CNC machining centers, lathes, and drill presses. Not configured as a dowel pin reamer or over/under size reamer.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle and workpiece are fully stopped before mounting or removing the reamer. Secure the straight shank firmly in a properly sized chuck or collet to prevent slippage during cutting. Always follow the tooling manufacturer's recommended speeds and feeds for solid carbide reamers and the specific workpiece material being machined.
