Hole saws are subject to particular heavy stresses and strains when sawing. During their manufacture it is important to use materials with outstanding bending properties. Our bimetal strip steels for hole saws are perfect for trouble-free processing. They deliver excellent process reliability and enable you to manufacture your hole saws particularly efficiently. Ultimately it is the very good wear resistance and quality that make your products stand out.
We use electron beam welding and laser welding processes in the manufacture of our longitudinal seam welded bimetal. Speak to us if you have any questions about our bimetal for hole saws.
Benefits at a glance:
 

  • carrier material with optimum bending properties
  • process reliability throughout all manufacturing stages
  • consistently high quality
  • excellent wear resistance of the teeth in the end product
