Makita has a deep line-up of concrete solutions, including premium carbide bits for concrete drilling. The Makita 5/8" x 18" SDS-Plus Bit, 3-Cutter (B-61145) features premium carbide tips for efficient drilling and longer service life. The 3-cutter design delivers the concrete-cutting capability of a 4-cutter bit but with the efficiency and speed of a 3-cutter. The bits are engineered to deliver rounder holes for more efficient anchor setting, and the flute design is engineered for faster dust removal than standard bits. Makita SDS-Plus 3-cutter bits are ideal for a range of general purpose drilling applications in concrete and reinforced concrete.
