TYE839-One Piece SDS-MAX Tunnel Bit

• Ideal for drilling large holes where the depth of the hole exceeds the practicality of a core bit
• Chisel and raker teeth are optimized for faster material pulverization
• SDS-Max shank one piece design maximizes energy transfer, while the wide land and substantial core thickness makes these tunnel bits durable even in large hammers
• The centering tip reduces bit walking for exact spot drilling
