Key Features to Look For

When shopping for metal drills, prioritize these attributes for the best performance:

  • Material and Coating: High-speed steel (HSS) forms the base, with titanium nitride (TiN) or black/gold finishes for extended life and reduced friction.
  • Point Design: 135-degree split points grip metal instantly, preventing slippage; pilot points add precision for thicker stock.
  • Length and Toughness: Mechanics length for reach, XL or impact-rated for heavy-duty use like with cordless drivers.
  • Set Variety: Comprehensive kits in indexed cases ensure you have the right size for any project.
  • Compatibility: Bits that pair well with high-torque cordless drills for efficient metal penetration.

These features make metal drills essential within our Power Drill Parts & Accessories lineup.
