The FDW Profi drill has an A-type dust removal spiral, wide and shallow, which increases the speed of cuttings removal and provides high productivity. The cylindrical body of the large diameter drill perfectly transfers the impact energy throughout the working part, reducing vibration and reducing tool wear. Packing: plastic hanger. The body of the drill is alloyed with chromium, which prevents it from expanding under the influence of high temperatures. The carbide insert with the addition of 5% cobalt ensures long operation of the drill without changing the diameter. Milling of the body of the drill is carried out after hardening, which eliminates the possibility of marriage of the so-called "deformed" drills.
