Bosch EXPERT SDS plus 7X Hammer Drill Bit 10x100x165mm

Lasts up to 3 times longer than standard drill bits - Drilling reinforced concrete is a difficult task that takes a lot of drill bits. Normal bits with two cutting edges fit into the armor and break. The Expert SDS plus-7X's integral carbide head is an advanced 4-prong milling cutter made from a single piece of the hardest metal: it won't jam or show any weak points during impact drilling. Thanks to the Bosch carbide technology and integral carbide head, the Expert SDS plus-7X lasts much longer than standard impact drills.
