The DeWalt DW5809 Rotary Hammer Bit offers a range of outstanding features. Its ROCK CARBIDE tip is designed to maximize the carbide's surface contact, which significantly extends the bit's lifespan. The four-flute design with a longer helix speeds up the removal of milled material, enabling faster drilling. The concave head design allows dust to quickly enter the flute chambers, further increasing the bit's durability. A hardened core is added to reduce the risk of breakage. This bit is versatile and fits all brands of SDS Max Rotary Hammers, including Dewalt, Bosch, and Hilti. Here are its specifications: the diameter is 5/8 inches, the usable length is 16 inches, and the overall length is 21-1/2 inches.
Using the DeWalt DW5809 is easy. First, make sure your SDS Max rotary hammer is turned off and unplugged. Insert the bit into the hammer's chuck until it clicks into place. Once it's securely in, you can turn on the hammer and start drilling. When drilling, apply steady pressure but don't push too hard as the bit is designed to do the work. Keep in mind that the bit works best on hard materials like concrete and stone. As for maintenance, after each use, clean the bit with a brush to remove any dust or debris. Store it in a dry place to prevent rust. Also, check the bit regularly for signs of wear or damage. If the carbide tip starts to wear down or the bit is bent, it's time to replace it. And always use safety gear like goggles and gloves when using this bit.
