Hertel 45676715 Chucking Reamer 0.415 in Solid Carbide

Product Description

The HERTEL 45676715 is a solid carbide chucking reamer designed to finish-size drilled or bored holes to tight tolerances. With a 0.415-inch diameter, 6 straight flutes, and a right-hand cutting direction, it produces precise, smooth bores in a single pass. The straight shank is compatible with standard drill chucks and collet holders. A bright polished finish reduces friction and aids chip evacuation. Overall length is 3.5 inches with a flute length of 1.25 inches. Machinists and tool-and-die tradespeople rely on this tool for high-accuracy hole finishing in steel, cast iron, and non-ferrous materials where dimensional control is critical.

This chucking reamer is suited for CNC machining centers, manual mills, drill presses, and lathes performing finishing operations in production or job-shop environments. It fits applications where a drilled hole must be brought to a precise finish diameter within the 0.4000- to 0.4999-inch range. Typical use cases include bearing bores, dowel pin holes, and precision fitment holes in machined components. The solid carbide construction makes it appropriate for harder workpiece materials and higher cutting speeds compared to high-speed steel alternatives.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• 6 straight flutes provide consistent cutting action and smooth bore finish
• Right-hand cutting direction standard for conventional spindle rotation
• Bright polished finish reduces built-up edge and aids chip flow
• Straight shank fits standard drill chucks and ER collet systems without special tooling
• 1.25-inch flute length suitable for shallow to moderate hole depths

Compatibility

Designed for use in drill chucks and straight-shank collet holders on CNC machining centers, manual mills, drill presses, and lathes. Suitable for finish-reaming holes in the 0.4000- to 0.4999-inch decimal inch diameter range.

Installation Notes

A licensed machinist or qualified toolroom technician should install and operate this reamer. Ensure the machine spindle is fully stopped and the tool is securely clamped in the holder before beginning setup. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not use this reamer as a drill to remove stock from a solid workpiece — pre-drill or bore the hole close to finish size before reaming.
