The cutter's premium carbide-tipped head and three-edge design deliver noticeably higher cutting speeds and a sharper finish than equivalent HSS bits, making it a strong choice for fabricators working with stainless steel, cast iron, and other hardened metals. The included pilot pin and 3\/4 in Weldon shank fit common mag drills, so setup is straightforward and drilling stays stable.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbide cutting edge:\u003c\/strong\u003e provides long-lasting durability for repeated use on harder materials like stainless steel and cast iron.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5\/8 in cutting diameter and 2 in depth:\u003c\/strong\u003e offers a practical size for many structural and fabrication holes without excessive weight or overkill.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/4 in Weldon shank (2 flat):\u003c\/strong\u003e ensures positive engagement with a range of magnetic drills for stable, accurate drilling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-edge cutting design:\u003c\/strong\u003e splits the workload across three edges to improve cutting efficiency, speed, and surface finish.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded pilot pin:\u003c\/strong\u003e simplifies centering and chip ejection, helping achieve cleaner holes in thick metal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat-resistant carbide tips:\u003c\/strong\u003e maintain hardness under high temperature cutting to reduce wear and prolong tool life.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe KEENTECH cutter is best for professional fabricators, maintenance technicians, and serious hobbyists who regularly drill holes in tougher metals such as stainless steel, carbon steel, cast iron, and alloy steel.
