: These are the "workhorses" of the industry. They are ideal for drilling alloyed and non-alloyed steels, cast iron, and non-ferrous metals.

: GOST standards define exact tolerances for diameter, flute length, and point angle. This ensures that a 10mm bit actually drills a 10mm hole. nabor sverl gost
