The IRWIN Tools 63112ZR 3/16-Inch Cobalt Alloy Steel 135-Degree Jobber Length Drill Bit-Bulk - Pack of 12 is made of M35 Cobalt Alloy Steel. The Cobalt Alloy Steel helps dissipate heat, which is the killer of all drill bits, providing it with longer life and more durability. The Cobalt Alloy Steel construction allows this bit to drill abrasive materials like stainless steel and cast iron which are extremely tough on traditional high speed steel drill bits. The bit has a 135-degree split point tip to help eliminate walking as you start to drill the hole in metal. The straight shank works in both keyed and key-less chucks.
