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.
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.
