The DeWalt DW5816 Rotary Hammer Bit offers outstanding performance. It has a 7/8-inch diameter, a 16-inch usable length, and a 21.5-inch overall length. The ROCK CARBIDE tip ensures more carbide surface contact, which extends the bit's lifespan. The four-flute design with a longer helix helps remove millings faster, enabling quicker drilling. The concave head design allows dust to enter the flute chambers rapidly, further increasing the bit's durability. A hardened core reduces the risk of breakage. This bit fits all SDS Max Rotary Hammers from brands like DeWalt, Bosch, and Hilti.


Using the DeWalt DW5816 rotary hammer bit is easy. First, make sure your SDS Max rotary hammer is turned off. Insert the bit firmly into the hammer's chuck until it locks in place. When you start drilling, apply steady pressure but don't push too hard. Let the bit do the work. As you drill, keep an eye on the dust. If it's not coming out smoothly, it might be a sign to clean the bit or adjust your drilling speed. After use, turn off the hammer and remove the bit carefully. To maintain this bit, clean it regularly with a brush to remove any dust or debris. Store it in a dry place to prevent rusting. Avoid dropping the bit or using it with a hammer that's not compatible, as this can damage the bit and reduce its lifespan.
