DeWalt DW5812 3/4 x 16 x 21-1/2 4-Cutter SDS Max Rotary Hammer Bit

Using the DeWalt DW5812 4-Cutter SDS Max Rotary Hammer Bit is quite straightforward. First, make sure your SDS Max Rotary Hammer is from a compatible brand like Dewalt, Bosch, or Hilti, and then insert the bit securely into the tool. When you start drilling, the long helix four - flute design will help remove chips quickly, so you can drill faster. The concave head design will take in dust rapidly, which is good for the bit's life. Remember, the hardened core makes it less likely to break, but still, avoid using excessive force. As for maintenance, after each use, clean the bit to remove any dust and debris. You can use a brush for this. Store it in a dry place to prevent rust. If you notice any signs of wear on the ROCK CARBIDE tip, it might be time to think about getting a new bit.
