The DeWalt DW5815 rotary hammer bit comes with excellent features. It has a 7/8-inch diameter, an 8-inch usable length, and a 13.5-inch overall length. The ROCK CARBIDE tip boosts carbide surface contact, which extends the bit's lifespan. The long helix four-flute design speeds up debris removal for faster drilling. The concave head design allows dust to quickly enter the flute chambers, also increasing the bit's life. Its hardened core reduces the risk of breakage. This bit fits all SDS Max rotary hammers from well - known brands like DeWalt, Bosch, and Hilti.


Using the DeWalt DW5815 is easy. First, make sure your SDS Max rotary hammer is turned off. Then insert the bit into the hammer until it locks in place. When you start drilling, apply steady pressure but don't push too hard. This bit is suitable for various drilling tasks, but it works best on hard materials. For safety, always wear protective goggles and gloves. When you're done using the bit, clean it with a brush to remove dust and debris. Store it in a dry place to prevent rust. Check the bit regularly for signs of wear or damage, and replace it if necessary.
