The Bosch SDS Plus-5X Hammer Drill Bit 8.0x100x160mm. The SDS plus-5X Drill Bit offers highly efficient drilling in reinforced concrete. The geometrical form of the 4-cutter head prevents jamming and breakage for optimal results. The “turn-angle” head and the large and short dust removal channels within the 4-flute design provide fast dust removal so the bit can slice through concrete and rebar quickly with reduced wear. The bit is intended for use on masonry concrete and reinforced concrete.
