Sandvik Coromant 8037372 Corner Radius End Mill

Product Description

The SANDVIK COROMANT 8037372 is a solid carbide corner radius end mill designed for precision milling operations in demanding metalworking applications. It features a 3/8-inch cutting diameter, a 0.015-inch corner radius, and three flutes arranged in a right-hand spiral configuration with variable helix and variable index geometry. These design characteristics reduce harmonic vibration and chatter during cutting, improving surface finish and tool life. Part of the CoroMill Dura series, this end mill is built from H10F carbide grade, suited for high-hardness and difficult-to-machine materials. Licensed machinists and toolroom technicians are the primary installers and operators of this tool.

This end mill is intended for use in CNC machining centers, manual mills, and toolroom environments where corner radius profiling, slotting, and peripheral milling are required. The 1/2-inch length of cut and 2-inch overall length make it well suited for moderate-depth passes in ferrous and non-ferrous materials. Its centercutting capability allows plunge entry, expanding its utility in contour and pocket milling operations. The single-end, straight-cylindrical shank fits standard 3/8-inch collet or end mill holders commonly found in production and job shop environments.

Key Features

• 0.015-inch corner radius reduces stress concentration at cutting edges and improves workpiece surface finish
• Variable helix and variable index flute geometry minimize chatter and vibration during cutting
• Centercutting design allows direct plunge entry without pre-drilling
• H10F solid carbide grade provides high hardness and wear resistance for demanding materials
• Bright/uncoated finish suitable for use with or without cutting fluid across a range of materials
• Right-hand cut and right-hand flute direction compatible with standard CNC and manual spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for standard 3/8-inch straight-cylindrical collet chucks and end mill holders used in CNC and manual milling machine setups. Part of the Sandvik Coromant CoroMill Dura series.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with end mill holder torque requirements and runout specifications. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge length before clamping. Verify runout with a dial indicator before beginning production cuts to avoid premature tool wear or workpiece damage.
