SDS-max 42mm 450/570

Details

application areas

• For drilling in (reinforced) concrete, masonry and natural stone

properties

• 3-cutting edge carbide geometry
  • Exactly circular bores, important for dowel fastenings and low-vibration operation for reduced stress on the user
• Short transition from carbide tip to drill spiral
  • Very good removal of drilling dust
• 3 steep, large-volume turns
  • Optimal removal of the drilling dust
  • Counteracts the development of heat in the borehole, lowers the frictional resistance and increases the service life of the drill
• 150 ° point angle with center point
  • Provides improved and faster drilling
• Wear mark on the hard metal
  • Produces true-to-size drill holes
• Shot-peened surface of the drill body
  • Reduces wear on the drill flute
• One-piece, soldered carbide drill head with diameters 16 mm - 28 mm
  • Ensures a very good and direct energy transfer from the hammer drill to the drill
• 4-part soldered carbide drill head with diameters of 30 mm - 42 mm
  • Stresses occurring during drilling can be better absorbed and the load can be better distributed

Processing instructions

• Reinforcement hit: Continue working with reduced pressure. The cutting edge geometry of a rock drill is only suitable for drilling reinforcement to a very limited extent.
