Product Description
The EXACT 4407023 is a high speed steel (HSS) step drill bit featuring a hex shank and a diameter range from 4 to 12 mm. It is coated with titanium aluminium nitride (TiAlN) for superior hardness and wear resistance, making it suitable for demanding industrial and construction applications involving tough materials.
This drill bit includes a spiral flute design with a dedicated deburring zone, allowing users to achieve burr-free drilling and efficient planing of sheet metal, pipes, and profiles. The TiAlN coating is engineered to perform effectively on challenging materials including construction steel, corrosion-resistant nickel steel (CrNi steel), and non-ferrous metals up to 6 mm thickness.
The step drill bit does not require centre-punching; it maintains a constant cutting angle throughout the drilling operation to ensure precision and reduce the risk of material damage. Clear diameter markings are laser engraved on every step for quick size verification, facilitating workflow efficiency.
Its three-faced driving shaft design prevents slipping inside drill chucks, enhancing operational safety and accuracy. This specialist drill bit is particularly recommended for industrial manufacturing, mechanical workshops, construction projects, and maintenance tasks requiring a versatile and durable tool.
