Top 10 Best M42 Cobalt Drill Bit Set

Set contains 29 m42 Cobalt Drill Bits sizes 116 - 12 x 164 increments. Cobalt Drills are effective in drilling tough, high tensile strength materials like stainless steel, Inconel, and titanium. Gold oxide finish acts as a lubricant and provides wear resistance. Round shanks allow use with a wide variety of tool holding systems. Manufactured to Aerospace Standard 907 and display high red hardness, permitting speeds up to 30 greater than with conventional M2 high speed steel. Cobalt steel provides extended tool life compared to high-speed steel drill bits, and maintains the tool's toughness and hardness in high drilling temperatures. Effortlessly grip the set in 1 hand as you would a travel coffee mug or leave it in the cup holder of your truck while on the way to a job. When all hands are on deck, hang the drill index on your belt whether you're in the shop or field.
