When starting to drill, the pilot point design will help you get a quick start and drill accurate holes. Simply place the bit on the concrete surface and start the drill. For fast drilling, the bit's optimized flute design will quickly remove dust from the hole. When drilling in areas with rebar, don't worry too much as the bit is designed to resist breakage when it strikes rebar. Regarding the no - break guarantee, keep an eye on the anchor wear mark on the flute. As long as it's still visible, if the bit fails, DeWalt will replace it for free. When the wear mark fades, it's time to replace the bit to ensure proper anchor installation. To maintain the bits, after each use, clean off any dust and debris. Store them in a dry place to prevent rust. With these tips, you'll get the most out of your DeWalt drill bits.
