Long drill bit for metal 11,5
Professional long drill bit for metal 11,5 cylindrical, extended with a diameter of 11,5 mm intended for drilling precise through-holes and blind holes in hard and hard-to-machine materials. Long drills for metal 11.5 cylindrical found in our store are in accordance with the dimensional standard NWKb, DIN 340 of modern HSS high-speed steel. This is a unique material that increases the efficiency and accuracy of cutting, and also increases the strength of the tools to withstand very difficult working conditions. The drill blades are resistant to breaking, cracking, breaking out and even dulling. Thanks to high-speed steel, high-speed drilling is possible, that is, at high speeds during which high temperatures are generated. The drills are even resistant to so-called thermal shock. The high quality of the drills is also due to their specific geometric design. The tools have 2 central blades, strong ground cutting edges and also special grooves for draining chips from the drilled hole.
