Hertel 45676954 Chucking Reamer 0.473 in Solid Carbide

Product Description

The HERTEL 45676954 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.473-inch reamer diameter, 4-inch overall length, and 6 straight flutes ground to a bright polished finish, this tool delivers tight-tolerance sizing in drilled or bored holes. The straight shank mounts directly in drill chucks, collet chucks, or machine spindles. Right-hand cutting direction suits standard CNC machining centers, knee mills, and drill presses. Solid carbide construction provides superior wear resistance and rigidity compared to high-speed steel, making it well suited for harder workpiece materials and high-production runs.

This chucking reamer is used in machine shops, manufacturing facilities, and maintenance environments where hole diameter accuracy and surface finish are critical. The 1-3/8-inch flute length provides effective chip clearance on through-holes and shallow blind holes. Its straight flute geometry works across a range of ferrous and non-ferrous materials. Machinists and tool-and-die technicians are the primary installers of this tool in production and job-shop settings.

Key Features

• Solid carbide construction for extended tool life in demanding materials
• 0.473-inch diameter for precision hole sizing within the 0.4000-0.4999-inch range
• 6 straight flutes with bright polished finish for smooth chip evacuation and bore surface quality
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight shank fits drill chucks, ER collets, and standard toolholders without adapters
• 4-inch overall length suits common machining center and drill press setups

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard drill chucks, collet chucks, and machine spindles accepting straight-shank tooling in the 0.4000-0.4999-inch diameter range.

Installation Notes

Installation is performed by machinists and toolroom technicians on CNC or manual machine tools. Power down and lock out the machine spindle before mounting or removing the reamer. Ensure the chuck or collet is clean and properly torqued to the manufacturer specification for the toolholder in use. Reamers are finish tools and should follow a drilled or bored hole that is already close to final size — do not use as a primary material-removal tool.
