YG-1 EM636 Carbide Corner Radius End Mill, Uncoated (Bright) Finish, 30 Deg Helix, 2 Flutes, 2.25" Overall Length, 0.125" Cutting Diameter, 0.25" Shank Diameter, 0.020" Corner Radius

Key features

• Corner radius end mills have cutting edges with rounded corners to reduce chipping and provide longer tool life
• Suitable for high-performance machining on tool steel, alloy steel, mold steel, and other high-hardened materials up to Rockwell hardness C70
• Stub length increases the strength of the tool, making it less likely to break in the workpiece
• Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than TiN and TiCN coatings
• High-performance carbide provides better wear resistance and toughness than standard carbide and can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures

The YG-1 EM636 TiAlN-coated carbide stub-length corner radius end mill has two flutes, a 30-degree helix, and a center-cutting design for high-performance machining on tool steel, alloy steel, mold steel, and other high-hardened materials up to Rockwell hardness C70. Corner radius end mills have a square end with rounded corners on the cutting edges to reduce chipping and extend the life of the tool. The stub length increases tool strength and makes it less likely to break in the material being machined. It is best used when depth of cut is shallow. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes into the material. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit. The 30-degree helix angle balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It also offers increased hardness compared to TiN and may reduce the need for lubricants based on the application.
