A set of 6 drills - tap drills made of high-speed steel HSS, which makes the drills exceptionally strong, durable, and resistant to wear, allowing work at high speeds. The surface coated with titanium nitride increases their hardness, resistance to wear, heat, and corrosion, and also reduces friction.

They are perfect for quickly creating durable screw connections in carbon steel, copper, brass, and plastics by making holes with simultaneous tapping of internal threads. Creating holes and precisely matched threads for screw assembly in one cycle speeds up work progress. They also allow for repairing damaged threads and shaping holes to screw sizes.
