Long drill bit for metal 5,5
Modern long drill for metal 5,5 cylindrical, twist drill made in accordance with the dimensional standard NWKb, DIN 340. The drill is suitable for drilling cylindrical through-holes and blind holes with a section of 5,5 mm. It has a tip angle of 118 degrees, spiral grooves for quick removal of chips from the drilled hole, and strong ground cutting edges that are resistant to lateral forces and impact. We recommend long drills for metal 5,5 characterized by very high resistance to mechanical damage, which makes them more durable and useful for professional processing. The offered drills are extremely rarely subject to cracks, fractures, chipping, dulling and other damage. The high durability of the drill bits to withstand harsh machining conditions is due to the use of special HSS (High Speed Steel) for their production. Thanks to its properties, it is possible to increase the efficiency of cutting, which works well in large workshops and locksmith shops, where there is a need for a more rational use of the available workstations. The offered drills can be used for conventional drills, lathes, milling machines and computer numerical control machine tools - CNC.
