Built from premium M35 cobalt steel (5 cobalt), these bits are designed to handle hardened metals such as stainless steel, high carbon steel, cast iron, and titanium alloys. A TiAlN coating helps manage heat and reduce friction, promoting consistent results and longer tool life in demanding tasks.\u003c\/p\u003e\n\u003cp\u003eWith 21 sizes spanning from 1\/16 in to 1\/2 in, this kit covers a wide range of drilling needs, from delicate pilot holes to larger through holes. The kit is organized for quick access, so you can focus on the task at hand rather than hunting for the right size.\u003c\/p\u003e\n\u003ch3\u003eSmart design for cleaner holes and safe operation\u003c\/h3\u003e\n\u003cp\u003eThree key design features set these bits apart. The triple-flute geometry delivers smoother hole finishes, faster chip ejection, and improved drilling accuracy compared to conventional two-flute bits. For small, delicate work the smallest sizes use a two-flute approach, while larger sizes use the triple-flute geometry for higher performance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e21 essential sizes from 1\/16 in to 1\/2 in\u003c\/li\u003e\n  \u003cli\u003eSmall sizes 1\/16 in to 7\/64 in use two-flute geometry for delicate work\u003c\/li\u003e\n  \u003cli\u003e3\/32 in and larger use triple-flute design for faster drilling and better chip control\u003c\/li\u003e\n  \u003cli\u003eThree-flat shank provides a secure, slip-free grip in high torque tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePerformance you can rely on\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN coated to resist heat up to 800 C, helping extend life in tough materials\u003c\/li\u003e\n  \u003cli\u003eM35 cobalt steel offers enhanced hardness and durability for demanding cuts\u003c\/li\u003e\n  \u003cli\u003eThree-flute geometry reduces bit walk and improves hole quality\u003c\/li\u003e\n  \u003cli\u003eComprehensive 21-piece set covers most common metal drilling tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNote that results depend on proper speed, feed, and lubrication.
