Product Description
EXACT 4407024 3-Piece Step Drill Bit Set for Metal provides enhanced performance with high-speed steel (HSS) bits coated with titanium aluminum nitride (TiAlN) to withstand tough materials.
The bits cover sizes from 4 mm minimum to 30 mm maximum, enabling efficient and precise step drilling on sheet metals, pipes, and structural profiles up to 6 mm thick.
Each bit features a spiral flute and a deburring zone, allowing simultaneous drilling and edge finishing, ensuring burr-free holes which optimizes manufacturing and maintenance operations in industrial, construction, and metal fabrication settings.
The two-sided deburring capability and absence of center-punching simplifies workflow, saving time and reducing secondary finishing steps.
This step drill bit set includes a three-faced driving shaft design to minimize slipping in drill chucks, maintaining consistent cutting angles for clean, precise holes in metals including construction steel and stainless steel variants.
The set contains three high-speed steel step drill bits with cutting diameters from 4 mm to 30 mm. TiAlN coating adds enhanced wear resistance and durability. Laser-etched diameters on every level provide quick size reference.
Designed for burr-free drilling and efficient deburring in one pass. Suitable for industrial and construction metalworking applications requiring precise hole-making. Allows faster production in sheet metal fabrication and pipeline assembly.
No requirement for center-punching due to stable drilling angle. Spiral flute design ensures chip evacuation and smooth drilling. German-made with high manufacturing standards ensuring quality and reliability.
This drill bit set is highly recommended for professionals in mechanical workshops, manufacturing plants, HVAC installations, and general construction environments where metal drilling with minimal reworking is essential.
