Overview

The NEIKO 10037A Left-Hand Drill-Bit Set is purpose-built for challenging fasteners and everyday maintenance. Crafted from high-speed steel with a titanium nitride coating, these bits offer strong edge retention, smoother cutting, and improved corrosion resistance. The distinctive left-hand design shines when paired with reversible drills and screw extractors, making it easier to back out damaged screws, bolts, and studs without excessive force.

What you get

  • Available in 5-piece, 13-piece, and 15-piece SAE sets for broad coverage and value.
  • 5-piece set uses M35 cobalt HSS; 13-piece and 15-piece sets use M2 HSS for durability and long life.
  • Sizes range from small pilot bits to larger cores (examples include 5/64" to 1/4" in the 5-piece; 1/16" to 1/4" in the 13-piece; up to 1-1/4" in the 15-piece).
  • Includes a metal index storage case with labeled slots for quick size identification and portable transport.

Design and performance

  • 135-degree split point with an angled tip promotes self-centering and reduces walking on initial contact.
  • Left-handed geometry works with reversible drills and screw extractors to simplify removal of damaged fasteners.
  • Titanium nitride coating enhances surface hardness and lowers friction for smoother cutting through tough materials.
  • High-speed steel construction delivers reliable performance across automotive, workshop, and home repair tasks.

Storage, care, and use cases

Keep bits organized and portable with the included metal index case. Each bit has a dedicated slot and size marking for quick identification on the job. This kit is well suited for automotive garages, home improvement projects, and general maintenance tasks where fastener extraction or precision drilling is needed.

Note: While these bits are designed for efficiency and reliability, results depend on material, drill speed, and technique. Use appropriate PPE and follow best practices for your specific project.
