PFERD TOOLS 25204077 SET STB HSSE 3TLG HSS-E Step drill bit set 1 pc(s)

HSSE step drill for drilling and deburring thin sheets, pipes and profiles made of different materials. For secure transmission of torque, all step drills have a triple shaft. The kit contains three HSSE step drills in 4–12 mm (9 steps), 4–20 mm (9 steps), 4–30 mm (14 steps) for industrial use. For secure transmission of torque, all step drills have a triple shaft. The break-proof plastic box protects the tools against dirt and damage. The HSS step drill bit can be fixed in place for easier tool selection and removal.


Technical data
- Number, contents: 3 pieces
- PFERD type: Set STB HSSE Co5 3
- Design: HSSE

Benefits:
- Drilling and deburring in a single step.
- Absolute smoothness and high cutting performance.
- Easy centering and drilling through high-quality drill tip.
- It is easier to pull back through the tool cone when the sheet is drilled through.
- Non-breaking chips are transported off cleanly as with a twist drill.
- The formation of surface cutting and cold welding on the cutting edges is avoided.

Application recommendations:
- Install HSSE step drills on sheet metal, pipes and profiles up to a thickness of 4 mm.
- For step drills without coating, use cutting oil or compressed air as cooling/lubricants.
