Armeg Single Tip QFDS SDS Plus Hammer Drill Bit for multiple hole drilling in masonry materials using an SDS Plus Machine. The cost effective and faster solution for producing holes in masonry. Hammer grade tungsten carbide tip gives extended life in the hardest masonry materials. Furnace brazing process uses a copper braze heated to 1100°C giving the ultimate bond between body and tip, allowing the drill bit to withstand greater pressure and produce a greater number of holes. Tip insertion is secured using purpose made machines operating to pre-set specifications and tolerances, ensuring a consistently accurate and perfectly centralised tip for rounder holes. SDS Plus can be used in heavy duty concrete, general concrete, hard bricks, soft bricks, lightweight blocks, natural stone, constructional granite and limestone. · · · Hammer Grade Carbide Tip · · Copper Brazed to 1100°C · · Precision Machining · · SDS Plus are ideal when drilling holes for fixings & anchors
