Some drill bits have coatings to improve their performance. Saw drill bits intended to cut through masonry have a diamond coating instead of a blade, which grinds cleanly through tile, brick, and other masonry. The blade attaches to a mandrel or arbor that, in turn, connects to the drill.

A saw drill bit has a cup shape with a saw blade that runs around the rim of the bit. Saw Drill Bit: A hole saw bit is for drilling large holes through wood, metal, plastic, tile, and even glass.These bits feature a shank that will only fit a rotary hammer drill. A rotary percussion bit has a harder tip that can withstand the impact. Rotary Percussion: A rotary percussion drill bit works with a rotary hammer drill that penetrates the material by creating an impact motion with the drill bit and rotating it.Double flute bits come in shanks that fit standard drills or rotary hammer drills. The double flute design can drill through concrete and other masonry twice as fast as standard drill bits.

Double Flute: A double flute drill bit has wide grooves that spiral around the bit to maximize the removal of material as it bores through masonry.Some bits have spear-shaped tips that allow for precision drilling, while others feature a crown-shaped tip that can efficiently grind through masonry. All bit types use large carbide tips that can penetrate stone. Masonry drill bits come in several variations, including rotary percussion, double flute, and saw drill bits.Some drill bits use diamond particles, which are welded to the cutting edge to chew through hard surfaces such as marble and granite. With that in mind, most masonry drill bits have steel shafts with a cutting tip made of tungsten carbide, which is much harder than steel and can grind through stone without dulling quickly. Masonry drill bits need to be hard enough to endure the rigors of drilling through concrete. Read on to learn about materials, bit type, drill compatibility, and other crucial factors to consider when choosing a masonry drill bit.
