3 pcs. The latest generation of multi-performance stepped drills, with TiAIN coating for maximum service life, significantly faster drilling with quiet processing, as well as greatly reduced burr formation when processing almost all thin-walled materials, such as conventional steel with a strength of up to 1300 N\/mm2, stainless steel, aluminum, cast iron, brass, copper, wood and plastics.
\n9 times longer service life and up to 50% higher cutting speed<\/p>\n
compared to conventional stepped drills without coating<\/p>\n
Improved centering and up to 100% faster spot drilling<\/p>\n
Exclusive fast grinding<\/p>\n
Acceleration of the overall drilling process<\/p>\n
Significantly lower thrust forces<\/p>\n
Optimized cutting geometry<\/p>\n
Completely smooth operation without binding to the workpiece
\nNo sheet metal deformation
\nImproved hole roundness
\nSignificantly reduced formation of burrs on the edges
\nUp to 80% reduction in the force exerted on the tool during the drilling process<\/p>\n
