The DeWalt DW5831 rotary hammer bit comes with some great features. It has a 2 - inch diameter, an 18 - inch usable length, and an overall length of 22.5 inches. The ROCK CARBIDE tip offers more carbide surface contact, giving the bit a longer lifespan. Its longer helix four - flute design speeds up mill removal for faster drilling. The concave head design lets dust quickly enter the flute chambers, which also extends the bit's life. With a hardened core, it's less likely to break. This bit fits all SDS Max Rotary Hammers from brands like DeWalt, Bosch, and Hilti.

Using the DeWalt DW5831 is easy. First, make sure your SDS Max Rotary Hammer is turned off. Then insert the bit firmly into the hammer's chuck. Once it's in, you're ready to start drilling. When using the bit, try to keep a steady hand and apply even pressure. This will help you drill more accurately and also prevent the bit from wearing out too quickly. As for maintenance, after each use, clean the bit to remove any dust and debris. You can use a brush to do this. Store the bit in a dry place to avoid rusting. Also, be careful not to drop the bit as it can damage the tip or the body. If you notice any signs of excessive wear or damage, it's best to replace the bit to ensure safe and efficient operation.
