Applicable materials Recommended for drilling all tiles, marble, artificial stone and granite.Not recommended for hard concrete, especially reinforced concrete. Use to drill holes in excessively hard materials will result in rapid diamond removal and a shortened service life. Step 1 1. Fix it on the angle grinder tightly with a wrench. Turn on the grinder, let the bits rotating in the air to check if there is a balance problem. Step 2 2. Place the drill at a about 45-degree angle, it will help position. Hold the machine very steadily and give gentle pressure to start drilling. Step 3 3. When you feel the drill bit has cut into the material( one edge of the hole is about to form), slowly stand the drill bit upwards to 90°. Step 4 4. Keep drilling vertically until the hole has been completely formed. Can shake slightly to help remove chips and dissipate heat. Don’t greatly sway. For hand drill or light hammer drill Need additional adapters If you install it on a hand drill or other machines, you need an adapter, such as SDS-Plus, Hex or Round plus shank adapters.If you are using this core drill bit on a hand drill, make sure the speed is higher than 2000 RPM. Typical hand drills are 2000-5000 RPM. Within this range, the faster the drill speed, the longer it will last. So we don't recommend for a cordless drill. The lithium drill has a lower RPM, about 1000 RPM.Do not use impact or hammer mode.
