Scientific Cutting Tools CR375125A Corner Rounding End Mill

Product Description

The SCIENTIFIC CUTTING TOOLS CR375125A is a double-end corner rounding end mill designed for producing consistent edge radii on machined workpieces. Built from solid carbide and coated with AlTiN+ for improved heat resistance and tool life, this end mill features a 1/8 inch radius, a 3/8 inch mill diameter, and three flutes. The right-hand cutting and right-hand flute direction make it compatible with standard CNC and manual milling setups. A double-end configuration maximizes usable tool life. Machinists and tool-and-die professionals in job shops, aerospace, and general metalworking install this tool for edge-breaking and radius forming operations.

This corner rounding end mill is suited for operations requiring precise, repeatable edge radii on ferrous and non-ferrous materials. The AlTiN+ coating performs well in dry or minimal-lubrication cutting environments at elevated temperatures. With a 3/8 inch shank diameter matching the mill diameter, it seats directly in standard collet chucks and end mill holders of the same bore size. It is appropriate for use on CNC machining centers and manual knee mills where edge quality and dimensional consistency are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting applications
• AlTiN+ coating provides oxidation resistance and extends tool life in high-temperature cuts
• Double-end design offers two usable cutting ends, reducing per-edge tooling cost
• 1/8 inch radius with a tolerance of 0.001 inch for precise, repeatable corner geometry
• Three-flute configuration balances chip evacuation and surface finish
• Right-hand cut and right-hand flute direction for use in standard milling spindles

Compatibility

Designed for use in standard 3/8 inch collet chucks and end mill holders on CNC machining centers and manual milling machines requiring a corner rounding end mill with a 1/8 inch radius.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 3/8 inch shank fully into a matched collet or end mill holder and torque the retention hardware according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the cut to protect both the tool and the workpiece.
