Makita SDS-Max 4-Cutter Bit is designed to work with SDS-Max Rotary Hammers to drill holes in concrete and reinforced concrete. Special impact-grade carbide combines with the 4-cutter technology for faster and more efficient drilling. The centering tip and central guiding action means faster and more accurate holes. 4-cutter technology for reduced friction and rapid dust removal. Central guiding action for accurate holes. Centering tip features a more aggressive design for faster hole starting. Aggressive head geometry in primary cutter engineered for use in reinforced concrete. Wear marking on primary cutter indicates bit wear. Made of the highest quality chrome nickel molybdenum steel; Special impact-grade carbide. For drilling holes in concrete; 16" usable length. For use with Rotary Hammers that accept SDS-Max shanks bits.
