Imagine carrying just one set of bits to the job site whether you need to drill into metal, concrete, wood, tile, or a combination of materials. Bosch brings that daydream into reality with their multiconstruction bits.
They optimized the custom tungsten carbide head of their bits with multiple diamond-ground edges to handle a wide range of materials. They give the bits steep spiraling ribbed flutes to clear dust and debris. And so your drill can get a better grip on the bit, they softened the shank. The bits are even tough enough to use in a hammer drill.
Bosch sells bits in diameters from 1/8″ to 1/2″ and in lengths of 3″, 6″, 8″, and 10″, depending on the bit. Pricing varies depending on size, but you can pick up the 6-inch 3/8″-diameter bit for about $9 at Amazon.
