[4] More productive, more efficient drilling processes, thanks to precisely optimized tool geometry With the new generation of our Supradrill®, FRAISA has developed an innovative process that enables precisely defined, dimension- dependent cutting edge rounding and a perfectly smoothed flute. The newly defined cutting edge rounding reinforces the cutting wedge precisely in the highest load zone, distributes the forces optimally and significantly reduces micro chipping. The result is robust and reliable cutting behavior with an expanded, universal field of application. The perfectly polished flute minimizes friction and ensures a stable, controlled chip flow – even in tough materials with changing chip conditions or large drilling depths. Together, cutting edge rounding and flute smoothing significantly reduce the cutting forces in the drilling process. This allows significantly higher cutting data to be selected, which leads directly to higher productivity and noticeably better energy efficiency. The FRAISA Nano-U² coating further expands this potential. The high-performance coating developed in-house offers a wide speed and load window and impresses with its high thermal load capacity and uniform, predictable wear behavior. In combination with the ultra-fine grain carbide HM MG10, the result is an exceptionally robust drilling tool, perfectly balanced between hardness and toughness. 00:00:03.000 00:00:03.500 00:00:02.500 00:00:04.000 00:00:04.500 00:00:05.000 00:00:05.500 00:00:06.000 00:00:06.500 4.000 3.000 3.200 3.400 3.600 3.800 2.000 2.200 2.400 2.600 2.800 1.000 1.200 1.400 1.600 1.800 -200 0 200 400 600 800 Axial force [N] 1000 N -35% Time [hh:mm:ss] Conventional drill – 1 hole Conventional drill – 500 holes Supradrill® – 1 hole Supradrill® – 500 holes Thanks to the newly developed cutting edge rounding and the ideally smoothed flute, axial forces are significantly reduced, for maximum performance
