  • 【M35 COBALT STEEL & DURABILITY】: Engineered with premium M35 Cobalt Steel, this drill bit set offers superior heat and wear resistance compared to standard HSS. Its hardened, honed cutting edges with a chatter-free design ensure professional-grade durability and clean, precise holes even when tackling hardened metals.
  • 【PRECISION PERFORMANCE】: Featuring a 135° split point and a fully ground twist design, these bits prevent "walking" on hard surfaces and ensure faster chip removal. The gold oxide finish reduces friction, making it the ideal choice for demanding industrial tasks, DIY projects, and heavy-duty maintenance.
  • 【EFFICIENT DUAL-FLUTE DESIGN】: The precision-engineered 2-flute form rapidly clears debris away from the hole, significantly decreasing heat buildup. This allows for a faster, cooler drilling process, which is essential for preserving the bit’s sharpness when working with tough alloys.
  • 【COMPREHENSIVE 99-PIECE SET】: This extensive jobber length set includes 99 pieces ranging from 1/16" to 3/8", covering both round and tri-flat shanks to meet all your drilling needs. It provides the versatility required for everything from delicate repairs to heavy-duty metalwork.
  • 【ADVANCED ORGANIZED STORAGE】: The upgraded storage case features a partitioned design with a clear size index. This specialized layout prevents bits from shifting or mixing during transport, ensuring your workspace remains organized and the exact size you need is always easy to find.
