These Multi-Material drill bits will drill through just about any type of material out there, including brick, block, tile, metal, wood, laminate, plastic and marble. The bits have a unique diamond-ground, four-facet carbide tip with super-sharp cutting edges designed to guarantee centered starts with no walking, fast drilling and excellent hole quality. The versatile bits have a double-milled flute that removes dust and debris quickly and efficiently, which not only increases drilling speed (with no clogging), but are designed to result in longer bit life as well. These bits are built tough for hammer drilling, but recommended for use in rotary mode. They are compatible with all standard 1/2-inch and 3/8-inch chuck drills. They are available in 3-inch to 5-inch jobber lengths and 16-inch extended length, with diameters ranging from 1/8 to 1/2 inches.
