SDS-max concrete hammer drills with 4 cutters.

1. Strengthening of the core with maximum power transmission. No risk of fracture when gathering armouring. Two big bore dust grooves ensure optimal removal of the bore dust. Reduced vibrations and less friction result in much less drilling time.
2. Applications: for drilling in granite, concrete, stone, masonry. Suitable in all hammer drills with SDSmax adaptor and two grove adaptor like Hilti TE 706 AVR, TE 56, TE 56 ATC, TE 76 ATC, TE 42 to 92.
