Sandvik Coromant 8036303 Square End Mill 1 in 4 Flute Altin

Product Description

The SANDVIK COROMANT 8036303 is a solid carbide square end mill designed for high-performance milling in demanding metal-cutting applications. With a 1-inch mill diameter, 4 flutes, and an AlTiN coating, this tool delivers excellent wear resistance and thermal stability during aggressive cuts. The variable helix and variable index geometry reduce chatter and vibration, improving surface finish and extending tool life. At 4.5 inches overall length with a 2-inch length of cut, it is suited to both roughing and finishing passes where rigidity and chip evacuation are priorities. Licensed machinists and CNC operators are the primary users of this tool.

This end mill is built for right-hand cutting with right-hand flute direction and is centercutting, allowing plunge entry where needed. The CoroMill Dura series is engineered for use in steels and high-temperature alloys where tool wear is a key concern. It fits standard 1-inch collet chucks and end mill holders on vertical and horizontal machining centers. The single-end configuration means the tool is replaced when the cutting end is worn. Material grade X1BH supports use in a range of ferrous and difficult-to-machine materials.

Key Features

• Solid carbide construction for maximum rigidity and wear resistance
• AlTiN coating provides high-temperature oxidation resistance and reduced friction
• Variable helix and variable index geometry minimize chatter and vibration
• Centercutting design allows axial plunge entry
• Right-hand cut and flute direction for standard CNC spindle compatibility
• CoroMill Dura series material grade X1BH suited for steels and high-temp alloys

Compatibility

Designed for use in standard 1-inch end mill holders and collet chuck systems on CNC vertical or horizontal machining centers. No specific machine model compatibility was provided by the manufacturer for this listing.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before tool changes. Seat the 1-inch shank fully into the holder and torque the retention system per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on carbide tooling.
