HSS Spiral Flute Step Drills



● Made from quality HSS (M2), good self-centering for easy and accurate cutting
● CBN ground and spiral flutes guarantee quiet running and high cutting performance
● Smooth cutting behavior, no sticking in the material, less burrs on the work piece
● Lower cutting forces and longer service life
● Used in sheets, pipes, profiles, CrNi steel, non-ferrous metals, plexiglass, wood etc.
● 9-step (4 -12mm): 4, 5, 6, 7, 8, 9, 10, 11, 12mm
9-step (4 -20mm): 4, 6, 8, 10, 12, 14, 16, 18, 20mm
14-step (4 -30mm): 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30mm
● Manufacturing standard: DIN1412C

● TiN (Titanium nitride) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide,
and aluminum components to improve the substrate's surface properties
● TiAIN (Titanium aluminium nitride) offers high resistance to heat and oxidation. This enables working with a higher cutting speed and thus
accelerating working processes. Compared to uncoated tools, TiAlN coating, depending on the application, increase an up to ten times longer
service life.
