DeWalt DW5224B25 DeWalt 1/4 x 4 Drill Bit Premium Percussion (Bulk 25)

Using these DeWalt drill bits is easy. First, make sure your drill is suitable for percussion drilling. Insert the bit into the drill chuck, ensuring it fits snugly with the three - flat shank to prevent slipping. When you start drilling, apply steady pressure. The four - flute design will help clear debris, so you can drill faster. As for maintenance, after each use, wipe the bit clean to remove any debris. Keep the bits in a dry place to prevent rust. Remember, the ROCK CARBIDE tip is what gives the bit a long life, so handle it with care to avoid chipping.
