Built to withstand demanding metalworking tasks, these bits use an upgraded cobalt alloy to deliver enduring cutting power in tough materials like stainless steel, cast iron, and titanium. They’re designed for higher heat conditions and aim for longer life compared with standard bits, while maintaining precise starts and steady performance through multiple holes.\u003c\/p\u003e\n\u003ch2\u003eKey alloy and construction\u003c\/h2\u003e\n\u003cp\u003eThe core is an upgraded M42 cobalt alloy, containing 8% cobalt. This composition enhances durability and heat resistance, helping the bits retain sharpness longer under high temperatures. When compared with standard HSS bits, cobalt variants can offer noticeably longer life in demanding jobs while maintaining accuracy in starts and hole integrity.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUp to 10x life vs standard bits\u003c\/li\u003e\n  \u003cli\u003eHigh-heat resistance for extended use\u003c\/li\u003e\n  \u003cli\u003eThick web-helix design for fast material removal and stability\u003c\/li\u003e\n  \u003cli\u003eSurface-hardened tip for penetrating tough materials\u003c\/li\u003e\n  \u003cli\u003eSplit point on 1\/8\" and larger improves starting accuracy; 3\/16\" and larger uses a three-flat shank for better grip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDesign details that matter on the job\u003c\/h2\u003e\n\u003cp\u003eThe thick web-helix geometry speeds material removal while preserving stability, reducing bit wobble during heavy cuts.
