SpeTool M02008 5Pcs CNC SC Spiral for Steel, Stainless Steel Metal with TiAlN Coating 2-Flute 1/8" Dia x 1/4" Shank x 1/2" Cutting Length x 2" Long Ball Nose Up Cut End Mills

Specification:  Flute number 2 End Cut Type Ball Nose Shank Diameter(SD) 1/4" Cutting Diameter(CD) 1/8" Cutting Length(CL) 1/2" Overall Length(OVL) 2" Coating TiAlN Material Carbide   Overview:  For longer tool life and a better finish in general-purpose milling applications, these solid carbide end mills are harder, stronger, and more wear-resistant than high-speed steel and cobalt steel end mills. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. The TiAlN-coated end mills dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication.    Designed for cutting the following materials:   Cast Iron Titanium Steel: 40-50HRC Carbon Steel Chrome Stainless Steel S
