Built with M35 cobalt material, these bits are designed to deliver hardness up to 67 and heat resistance that helps maintain sharpness during tougher drilling tasks. The set includes 13 sizes (1\/16\" to 1\/4\" in 1\/64\" increments) and ships with a convenient index holder, making it easier to grab the right bit on the job. Expect a longer service life compared with standard HSS options, enabling fewer replacements over time.\u003c\/p\u003e\n\u003ch3\u003eWhy these bits stand out\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCobalt M35 material:\u003c\/strong\u003e hard, heat resistant, and capable of cutting faster, with life up to 12x longer than the average HSS titanium-coated bit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSolid bonding 1\/4 hex shank:\u003c\/strong\u003e designed to stay secured in the chuck, helping duties run true and reducing unwanted slippage.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank stability under torque:\u003c\/strong\u003e 5x higher torque resistance reduces radial runout and improves concentricity for cleaner holes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eVersatile metal drilling for hard materials\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEngineered to drill through stainless steel, cast iron, and zinc alloys, expanding your capabilities beyond softer materials.\u003c\/li\u003e\n  \u003cli\u003eCompared to some titanium-plated versions, these cobalt bits are built for harder metals, which may reduce the need for frequent tool changes on demanding tasks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSize range and organization\u003c\/h3\u003e\n\u003cp\u003eThe 13-piece set covers common hole sizes from 1\/16\" up to 1\/4\".
