SDS Plus Drill Bit 10mm x 210mm S4L

SDS-plus S4L drill bits:
Extremely long lifetime in concrete and reinforced concrete.

Even more accurate drilled holes:

• Optimized drill bit flute surface.

Inductive brazing and hardening technology:

• Hardening in two steps:
  1. High-temperature brazing of the drilling head.
  2. Hardening/Annealing.
• Different hardness of head and flute optimized for any drilling diameter.

Special surface treatment of the flute:

• Stronger surface compaction.
• Consistently smooth surface.
• Longer lifetime due to less friction.
• Faster drilling dust removal.
