NWKpextra-long metal drill fi 5,5 cylindrical, extra-long drill with a diameter of 5,5 mm and a length range of 260/180. The drill is designed for drilling very deep holes, including drilling of concave profiles. In our store we recommend NWKp drill bits that comply with the dimensional standard DIN 1869 and have a tip angle of 118 degrees. Their use does not require pre-drilling, scoring and pilot drilling. The drills are ground, made entirely of modern HSS (High Speed Steel). Their advantage is very high hardness and durability. Machining even in very harsh conditions does not reduce the quality of cutting. The drills we offer are resistant to breaking, cracking, chipping, chipping, breaking out and other mechanical damage. Thus, the drills can be used for a long time without the need to buy new tools.
