💡 What is a solid carbide end mill used for in metalworking? Solid carbide end mills are handy tools for precise milling in steel and iron, with some aluminum capability. - Solid carbide end mills provide stiffness and long tool life in hard metals (0.25" dia / 6.35 mm)
- AlTiN coating boosts hardness and heat resistance for extended runs (0.25" dia)
- 30° helix helps with chip evacuation and reduces chatter in deep pockets
