Using these Bosch hammer drill bits is a breeze. First, make sure your drill is turned off and unplugged if it's corded. Select the right bit from the 25 - piece set according to your project needs. Insert the bit into the standard chuck of your hammer drill or impact driver. Once it's securely in place, you're ready to start drilling. When starting, use the multi - grind centering tip to get an accurate and precise start on the surface. This works great on materials like brick, masonry, and concrete. Remember to keep the drill perpendicular to the surface for the best results. As you drill, the milled U - flutes with deep - cut spirals will quickly remove the dust, so you can see what you're doing. Regarding maintenance, after each use, wipe the bits clean with a dry cloth to remove any dust or debris. Store them in a dry place to prevent rusting. Also, avoid using these bits on materials they're not designed for, as this can damage the bit and reduce its lifespan.
