The highest degree of position accuracy is guaranteed in each case.

Diamond coated carbide drill bits are a unique type of tungsten carbide center drill that offers a double advantage. These drill bits are specifically designed for center drilling difficult-to-machine materials. Traditional centering drills tend to wear out quickly due to the intense heat generated during drilling. However, diamond coated carbide drill bits have the advantage of through-tool cooling, which helps maintain a consistently low machining temperature and provides lubrication to the drill tip. This cooling feature proves beneficial even when drilling in hard-to-reach areas with protruding edges, ensuring that the cooling medium reaches the desired spot at all times. Additionally, diamond coated carbide drill bits can also be used effectively with external cooling. Regardless of the application, these Diamond Coated Drill Bits guarantee the highest level of position accuracy.
