Drill America DAM Series Masonry Drill Bits are engineered for efficient drilling in brick, concrete, and sandstone using portable electric drills. Built for performance, these bits feature wide flutes that enable rapid dust removal when working in softer masonry materials. Each bit has a durable round shank compatible with a wide variety of tool holding systems. The carbide tips are precision-brazed to tough steel bodies and are slightly oversized relative to the nominal drill diameter, ensuring proper clearance for installing anchor screws, expansion shields, and toggle bolts. The DAM Series delivers the rugged reliability professionals demand in masonry drilling applications.
