Hertel 45676970 Chucking Reamer 0.475 in Solid Carbide

Product Description

The HERTEL 45676970 is a solid carbide chucking reamer designed for precision hole finishing in machining applications. With a 0.475-inch cutting diameter and a 4-inch overall length, this reamer delivers tight-tolerance sizing in drilled or bored holes. The 6-flute straight flute configuration and right-hand cutting direction support smooth material removal and a consistent surface finish. The bright (polished) coating reduces built-up edge and aids chip evacuation. The straight shank interfaces directly with standard drill chucks and collet holders. Machinists and toolroom professionals specify this reamer when close-tolerance hole sizing is required in production or job-shop environments.

This chucking reamer is suited for precision finishing operations on metalworking lathes, drill presses, milling machines, and machining centers. The 1-3/8-inch flute length provides adequate cutting engagement for through-holes and shallow blind holes in the 0.475-inch diameter range. It is appropriate for use in ferrous and non-ferrous materials where dimensional accuracy and bore surface quality are critical. This tool is a single-piece solid carbide construction, making it well suited for rigid setups where runout must be minimized.

Key Features

• Solid carbide construction for wear resistance and dimensional stability in precision reaming
• 6 straight flutes with right-hand cutting direction for consistent, smooth bore finishing
• Bright (polished) finish reduces friction and helps clear chips during operation
• Straight shank for direct chuck or collet mounting without adapters
• 0.475-inch diameter falls within the 0.4000 to 0.4999 inch reamer diameter range
• Compact 4-inch overall length suits standard machine setups with limited Z-axis clearance

Compatibility

Designed as a standard chucking reamer for use in drill chucks, ER collet systems, and other straight-shank toolholders on lathes, milling machines, drill presses, and CNC machining centers requiring 0.475-inch diameter hole finishing.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations and cutting tool setup. Secure the straight shank firmly in a collet or drill chuck, ensuring minimal runout before operation. Power down and lock out the machine spindle before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
