Eagle Cutting Tool CR-3750-60-I Hss Center Reamer 60 Degree

Product Description

The EAGLE CUTTING TOOL CR-3750-60-I is a high-speed steel (HSS) center reamer designed for precision countersinking and center-hole finishing in metal workpieces. Built with a 60-degree included angle and three flutes, this reamer produces clean, accurate center holes used as reference points in lathe and grinding operations. The 3/8-inch body diameter pairs with a 1/4-inch shank, making it compatible with standard drill chucks and collet systems. Machinists and tool-and-die professionals rely on this style of center reamer to restore or refine center holes on shafts, spindles, and cylindrical stock before between-centers machining.

This center reamer is suited for use in manual and CNC lathes, milling machines, and drill presses across job shops, maintenance facilities, and production environments. The 60-degree angle matches the standard center angle used in most lathe tailstock centers and live centers, making it a practical choice for general-purpose center hole preparation on ferrous and non-ferrous materials. The 1/4-inch shank fits commonly available toolholders without adapters in most light-duty setups.

Key Features

• 60-degree included angle matches standard lathe center geometry
• Three-flute design provides balanced cutting action and smooth finish
• High-speed steel construction offers good wear resistance on a range of metals
• 3/8-inch body diameter for accurate center hole sizing
• 1/4-inch shank fits standard drill chucks and collet holders

Compatibility

Designed as a standard center reamer for use in lathes, drill presses, and milling machines requiring a 60-degree center hole angle with a 1/4-inch shank interface.

Installation Notes

Center reamers are typically installed and operated by machinists using manual or CNC lathes, drill presses, or milling machines. Secure the shank firmly in the chuck or collet before operation and ensure the workpiece is clamped or chucked without play. Run at appropriate speeds for the workpiece material and reamer diameter to avoid chatter or premature wear. Never force the reamer into an undersized pilot hole.
