Tork Craft Precision-Max Step Point Drill — 4.0 mm HSS (1 Piece)

Engineered for accurate holes and reliable starts, this 4.0 mm high-speed steel (HSS) step-point bit features self-centering geometry to reduce walking. Ideal for mild steel, aluminium, plastics, and thin sheet materials where precision entry is key.

Extra Information

  • Apply cutting fluid when drilling ferrous metals to extend bit life and improve surface finish.
  • Back up thin sheet materials with scrap to reduce exit breakout.
  • Use steady feed rates and avoid sudden force that can deviate or break the bit.

Pro Tip

  • Peck drill (withdraw bit periodically) in deeper holes to clear chips and control heat buildup.
  • Rotate new bits among your workload to spread wear evenly and maintain consistent hole quality.

Features

  • 4.0 mm diameter — suitable for larger pilot holes and small fasteners.
  • Step-point tip — self-centering design for reduced wander and clean entries.
  • HSS construction — strikes balance between toughness and wear resistance.
  • Straight shank — compatible with standard 3-jaw chucks.
  • Single-bit packaging — ideal for replacements or occasional use.

Benefits

  • Cleaner starts: step-point geometry helps produce balanced, burr-minimized entries.
  • Improved control: self-centering tip reduces need for pilot punches.
  • Versatility: effective in metals, plastics, laminates and composite materials.
  • Efficiency: direct start reduces setup errors, especially in tight or delicate assemblies.

Safety

  • Wear eye protection — chips, shards, or swarf may eject during drilling.
  • Secure your workpiece firmly; never hold by hand when drilling.
  • Do not force the tool; apply smooth, consistent feed pressure.
  • Manage tool speed, cooling and breaks to avoid overheating the bit or workpiece.
