DeWalt DW5857 1-3/8 x 31 x 36 4 Cutter SDS Max Rotary Hammer Bit

Using the DeWalt DW5857 is easy. First, make sure your rotary hammer is compatible with SDS Max bits. Insert the bit firmly into the tool's chuck until it locks in place. When you start drilling, apply steady pressure but don't push too hard as the bit's design is made to drill efficiently on its own. As for maintenance, after each use, clean the bit to remove any dust or debris. You can use a brush or compressed air for this. Store the bit in a dry place to prevent rusting. If you notice the bit is not drilling as effectively as before, it might be time to replace it. Keep in mind to always wear appropriate safety gear like goggles and gloves when using this bit.
