  • Cobalt High-Speed Steel Drill Bit:These bits are made of cobalt-containing high-speed steel with a titanium nitride coating, which has high hardness properties that allow them to easily penetrate hard materials, while also reducing friction between the bit and the material and lowering the temperature of the bit during operation.
  • 135-Degree Double-Edged Design: These drills utilize a 135-degree cutting edge with a twisted design and a hardened and polished cutting edge that prevents runout and allows for more precise hole placement.
  • Left-Handed Design: These drills are left-handed in design and can be used with a screw extractor in addition to a hole punch to remove damaged screws.
  • Comprehensive Size: This set includes 13 1/16“-1/4” drill bits. (1/4“, 15/64”, 7/32“, 13/64”, 3/16“, 11/64”, 5/32”, 9/64“, 1/8”, 7/64“, 3/32”, 5/64“, 1/16”)
  • Easy Storage: This drill set comes with a tin box with a size index to help you to organize the drill bits after use and prevent mixing up different sizes of drill bits
