Turbomax is a special drill bit designed for high-performance drilling. For portable drills. Produced in the Danish Irwin joran factory. They are made of W9 high-speed steel, resistant to high temperatures, which gives the drill bit exceptionally sharp cutting edges. Additionally, it is hardened, which provides exceptional resistance to wear and a hardness of 63-66 HRC. The Jet Point blade with a 100-degree angle provides the most precise centering and guidance - without slipping or puncturing, even on curved surfaces. Precise grinding extends the drill bit's sharpness and allows for faster drilling while requiring less force than a 118-degree tip. It also speeds up the start of work. The cutting collar with a 140-degree angle creates perfectly round holes and smooth finishes. It also guarantees clean holes without burrs and eliminates the drill bit from getting stuck in material layers. The reinforced and ground spiral made from a single block provides additional strength and durability, limiting the drill bit's breakage. The 3-flat handle prevents the drill bit from slipping out of the chuck and directs energy to the cutting edges, increasing drilling power. It also ensures a firm and safe grip, especially when using keyless chucks.
