  • 🔥【 5X Longer Lifespan in Hardened Steel】 Crafted from M35 cobalt high-speed steel with 5% cobalt core, these drill bits withstand temperatures up to 1200°F—outlasting standard bits by 5 times in hardened steel, stainless steel, and cast iron. Ideal for automotive, metal fabrication, and heavy-duty drilling.
  • ⚡️【 40% Faster Chip Removal with Triple-Flute Design】 The unique three-flute geometry cuts smoother and ejects chips 40% faster than traditional bits, reducing clogging and breakage. Perfect for deep-hole drilling in metal, aluminum, and tough alloys.
  • 🎯【 Precision drilling with TiAlN Nano-Coating】 Featuring a TiAlN coating rated at 89HRC hardness and a 135° self-centering tip, these bits drill through 1/4" stainless steel in under 8 seconds—no pilot hole needed, no wandering.
  • 🛠️ 【Non-Slip Grip for High-RPM Drilling】 The three-flat shank design locks securely into all chucks, including impact drills, preventing slippage even at 3000 RPM. Ensures stable performance under extreme conditions.
