Makita B-61195 3/16" x 8" SDS-Plus Bit 3-Cutter 10 Pack Makita has a deep line-up of concrete solutions, including premium carbide bits for concrete drilling. Makita SDS-PLUS 3-Cutter Bits feature 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.3-cutter bit tip is engineered for drilling in reinforced concreteCentering tip features a more aggressive design for faster hole startingCentral guiding action engineered for more accurate holesAggressive head geometry in primary cutter engineered for use in concreteEngineered for reduced vibration6" usable lengthFor use with Rotary Hammers that accept SDS-PLUS shank bits Makita has a deep line-up of concrete solutions, including premium carbide bits for concrete drilling.
