Because of this, dust masks or respirators are essential when using masonry drill bits, even for a short time. Concrete dust in particular is especially dangerous to your respiratory system, and contains microscopic silica particles that can cause short-term breathing issues, and long-term lung damage. The dust created by drilling into concrete, brick, and stone, is harmful to humans in several ways, so it’s important to use the proper safety precautions. That said, working with masonry is especially hard on drill bits, and even the most durable options are going to wear out quicker than you think. But, if you know exactly what you’re using your bit for, like drilling a pilot hole in a concrete wall, and don’t have the need or budget for a full set, masonry drill bits can be purchased individually. If you want to be prepared for a variety of drilling tasks, I recommend purchasing a set with a range of sizes, in particular, 1/4- and 5/16-inch options. Drill bits with hex shanks fit into regular cordless drills, and bits with SDS+ shanks only fit rotary hammer drills. These drill types have different chucks–the opening that holds the bit in place–which only accepts a certain type of shank–the end of the bit that fits into the chuck. It’s essential that your masonry drill bit is compatible with the drill you plan on using, whether that’s a standard drill with a hammer mode setting, or the larger rotary hammer drill. These hollow saws use a diamond coating to grind through stone, removing a solid core that is then ejected using an opening on the side of the saw. Hole Saw: For cutting large holes through extra-hard material like granite or porcelain, a masonry hole saw is best. ![]()
