Eagle Cutting Tool CR-3750-82-I Hss Center Reamer 3/8 in

Product Description

The EAGLE CUTTING TOOL CR-3750-82-I is a high-speed steel (HSS) 82-degree included-angle center reamer designed for countersinking and center-hole finishing operations in metal fabrication and machining applications. The tool features a 3-flute cutting geometry that provides smooth, consistent material removal and improved chip evacuation compared to single-flute designs. With a 3/8 inch cutting diameter and a 1/4 inch shank, it mounts directly into standard drill chucks, collets, or quick-change toolholding systems. This is an imperial-dimension tool suited for precision center hole work on lathes, drill presses, and milling machines.

This center reamer is intended for use in machine shops, production environments, and maintenance repair operations where accurate 82-degree center holes are required for standard imperial fastener countersinks or lathe center preparation. It is appropriate for use on steel, aluminum, brass, and similar machinable metals. Machinists, tool and die makers, and maintenance technicians are the primary users of this tool type. The 3-flute configuration makes it well-suited for both hand-fed and power-fed drilling setups where chatter reduction and surface finish quality matter.

Key Features

• 82-degree included angle matches standard imperial countersink and center hole geometry
• 3-flute design improves chip clearance and reduces chatter during cutting
• High-speed steel (HSS) construction provides good wear resistance across common machinable metals
• 3/8 inch cutting diameter with 1/4 inch shank for compatibility with standard toolholding
• Imperial dimensioning for use in standard inch-based machining workflows

Compatibility

Designed as an OEM-style replacement or direct-use center reamer for standard imperial machining setups requiring an 82-degree angle. Compatible with drill chucks, collets, and quick-change holders accepting a 1/4 inch shank.

Installation Notes

Installation is performed by machinists or qualified machine operators. Secure the 1/4 inch shank firmly in the toolholder before operation and verify runout is within acceptable limits for the application. Always bring the spindle to a complete stop before changing or adjusting the tool. Follow applicable shop safety protocols and machine manufacturer guidelines for feed rate and speed selection when using HSS tooling.
