Vr dynamic engineers splies tungaloy`s new generation of high performance drill - the dsx drill. The product range includes: 3, 5 and 8 x d and thus grants for optimal performance as individually requested. The surface quality of the flash coat drills ranges at ra < 0.10µm, providing for smooth chip flow even at deep hole drilling with low coolant pressure. This important feature is further supported by the design of the flutes increasing with growing drilling depth. The innovative design of the cutting edges combined with modern substrate and coating technology, which provides an excellent results for different applications and work materials such as steels, stainless steels, cast irons, non-ferrous metals, heat resistant materials and hardened steels. Some of the important features of dsx solid carbide drill include: new basic substrate for more rigidity; large flures for optimal chip flow; innovative tiain based coating technology; linear main cutting edge for easy regrinding; 3 x d, 5 x d and 8 x d; suitable for miniumum quantity lubrication.
