If you’re using a rotary hammer drill, you’ll need a specialty drill bit (SDS or SDS-MAX for holes up to 16mm in diameter, or Spline-Shank for larger holes). When choosing your drill bit, ensure that the flutes of the bit are at least as long as the hole you plan to drill, as this will enable you to remove any dust from the hole. These are designed to withstand the force of hammering, and are ideal for drilling dense concrete. ![]() You’ll need a high quality masonry drill bit to insert into your hammer drill, specifically a carbide-tipped bit intended for hammer drills. Try to choose a drill with at least 7 to 10 amps, and ideally a speed setting, depth stop, comfortable grip, and a second handle for your other hand to add stability.īefore commencing with your drilling, make sure to read the user manual and familiarise yourself with the features of your drill, to ensure that you’re comfortable with using it. Regular rotary drills are designed to shave the material away, which works well for metal and wood, but not so much for concrete, resulting in a slower and more difficult process.įor this reason, if you’re drilling anything more than a few small holes in cosmetic (non-structural) concrete, renting or even purchasing a hammer drill is a worthwhile investment.
