What's Included: This set has everything you need for your project. Features: The ROCK CARBIDE® tip offers more carbide surface contact, extending the bit's lifespan. The open head design efficiently directs dust into the flutes, enabling faster drilling. The longer helix four-flute design speeds up mill removal, making drilling quicker.

To use this DeWalt DW5855 rotary hammer bit, first make sure it's properly inserted into your SDS Max rotary hammer. Start the drilling process at a slow speed and gradually increase as needed. When drilling, apply steady pressure but don't push too hard as it can damage the bit. After each use, clean the bit with a brush to remove dust and debris. Store it in a dry place to prevent rusting. If you notice any signs of wear or damage, it's best to replace the bit to ensure optimal performance.
