  • 【TiAlN Coating: Extreme Heat Resistance for Longer Life】 Increases surface hardness to 89HRC with outstanding heat-resistance, so your drill bit cuts fast and stay sharp. This translates directly to a multi-fold increase in usable life compared to uncoated or standard TiN-coated bits, maintaining a sharp cutting edge through demanding jobs and lowering the long-term cost.
  • 【Special Tip Design】 Featuring a revolutionary 7-facet point, this cobalt stubby drill bit set outperforms standard 3-edge twist drills, extending tool life by 8-10 times while boosting cutting efficiency. Enhanced heat dissipation and clog-resistant chip clearance ensure superior performance in hard metals, stainless steel, and more.
  • 【M35 Cobalt Steel】 Short drill bits crafted from premium M35 cobalt steel, these bits achieve up to 3X longer tool life compared to standard HSS. This drill bit excels at drilling tough materials like stainless steel and cast iron, while also handling softer metals (copper, aluminum, iron), common alloys, wood, and plastic.
  • 【Professional Popular Sizes】 This versatile drill bits set includes seven popular sizes: 3/32", 1/8", 3/16", 1/4", 5/16", 3/8", covering the most common drilling needs and eliminating the need for multiple bit sets. Every bit is securely held in a robust, compartmentalized storage case.
  • 【Universal 1/4" Hex Shank】 The hex shank enables rapid bit changes while providing a significantly tighter, slip-resistant grip that transfers higher torque—perfect for demanding, high-intensity applications.
  • 【Versatile Performance】 Ideal for a wide range of applications including DIY, home repairs, auto maintenance, woodworking, and metal fabrication. 90 days warranty — in the event that you are not completely satisfied with your purchase for any reason, please reach out to us, and we will gladly provide a 100% refund or replacement.
