CONSTRUCTION EQUIPMENT::
ROTARY BIT, SDS TUNNEL BIT 2-1/8"

• Ideal for drilling large holes in masonry where the depth of the hole exceeds the depth of a standard core bit
• Solid tungsten carbide head
• Two flute design for faster clearance of debris
• Solid one piece system transfers power directly to the end of the bit
• Asymmetrical tungsten carbide teeth for faster drilling and longer life
• Carbide-tipped centering point helps reduce bit walking for more accurate drilling
• Larger diameters than standard carbide bits which allow smaller hammers to drill larger holes
• For making through-holes in masonry for piping, ventilation and electrical installations
• For use in concrete, block and brick
• 24" overall length; 18" usable length
• For use in rotary hammers that accept SDS-MAX bits
