Metal drill bit EXPERT/EXPERT 5.5x93mm (pack 10pcs) Cutop 53-484

The drill is made of high-quality HSS steel. Unique step quenching provides extremely high hardness of the cutting edge and the drill shank, and also contributes to increased fracture resistance. The drill has a 135-degree split point angle, which ensures low runout and allows for precise and consistent holes. Thanks to an alloy with the addition of 6% Tungsten and 5% Molybdenum, the drill can withstand high temperatures, and 4% Chromium and 2% Vanadium in the composition prevent corrosion, extending the service life of the product. It is intended for drilling holes in carbon and alloy steels, gray and malleable cast iron, non-ferrous metals, and plastic. Material: high-speed steel. Packaging: hanging plastic box.
