SDS plus-5X Drill Bit. 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. For efficient work and exact hole diameters, the centering tip guides drilling from the start, to prevent wandering, which can falsify the hole diameter. The bit is intended for use on masonry, concrete and reinforced concrete. It is compatible with rotary hammers with SDS plus holders.
