If you go through 1/8-inch bits often—or need a bit that’s better suited for harder metals—this RCINDUS 20-pack is a practical value pick. It includes twenty 1/8" (3.175mm) jobber-style drill bits packed in a plastic storage case, so you can keep spares on hand without digging through a toolbox.

The bits are made from industry grade M35 high speed steel with 5% cobalt. Pair that with a 135-degree split-point tip, and you get improved self-centering to help reduce walking when starting holes on tougher surfaces.

  • 20-piece pack of 1/8" (3.175mm) drill bits with included plastic storage case
  • M35 high speed steel with 5% cobalt for drilling harder metal vs. standard HSS
  • 135° split-point, self-centering tip helps improve starts and reduce walking
  • For steel, stainless steel, cast iron, plastic, PVC board, and wood
  • Spiral flute, 2-flute design with straight shank

Good fit for DIYers, mechanics, and shop users who want a consistent 1/8" size on hand for repeat drilling tasks across metal and mixed materials.
