Makita B-59178 15/64" x 5" SDS-Plus Drill Bit, Metal

If you regularly use a rotary hammer, Makita SDS-Plus drill bits for metal deliver new levels of convenience and performance. The drill bits have an SDS-Plus shank and allow drilling in metal without Switching to a drill or using a special chuck adapter. The bit is engineered for use with a rotary hammer in rotation mode, but includes a specially-designed shorter shank to help prevent damage from accidental use in hammering with rotation mode on rotary hammers. The bit is made of ground high-speed steel (hss-g) for longer life, with a 135-degree split-point geometry for fast starts and reduced walking.
