PFERD Step Drills are sturdy high-performance tools for burr-free drilling and deburring of sheet metal, pipes and profiles. Materials up to 4 mm thick can be drilled and deburred easily in a single step. PFERD also offers step drills with a high-quality HICOAT coating. To ensure reliable torque transmission, all step drills have a three-surface shaft.
Advantages:
- Drilling and deburring in a single step.
- Completely smooth running and a high cutting performance.
- The high-quality drill tip ensures effortless centring and drilling.
- The tool taper makes it easier to pull back from drilled plates.
- Chips which do not break are neatly removed as with a spiral drill.
- Built-up edges and cold welding on the blades are prevented.
Materials that can be worked:
- Steel
- Cast steel
- Stainless steel (INOX)
- Non-ferrous metals
- Plastics
Applications:
- Drilling
- Deburring
Recommendations for use:
- Only use machines that are intended for use with the relevant tool.
- Ensure correct Personal Protective Equipment is worn while using the tool.
- Use HSS step drills on sheets, pipes and profiles with a maximum thickness of 4 mm.
- Use cutting oil/compressed air as a coolant and lubricant in the case of step drills without a coating. (Smoother drilling action and extended service life.)
- Avoid material cross contamination.
