3-edged right-cut ground spiral cobalt drill bit for steel and stainless steel with cylindrical shank Diameter: according to the selected variant Drill length: Short series - see attached photo for lengths Material: HSSE - High speed steel + Co5 / HSSCo5 Standard: DIN338 (replaces PN 2907 / PN2907) Usage : Stand and column drills, NC and CNC machines, possibly also hand drills. Structural steel Unalloyed and alloyed steel, cast steel with strength up to 850N/mm2 Stainless steel Wrought aluminum alloys and other aluminum alloys Advantages : Higher geometry / hole ovality - depending on the machine used, accuracy up to IT9 can be achieved. Thanks to three blades, the feed can be increased by up to 60%. The special geometry of the tip of the drill prevents the drill from slipping. Thanks to this, there is no need to use a punch to center the holes. The drill does not jam when re-drilling an existing hole. The chip is removed without a problem, less wear on the drill bit / longer service life, thanks to the distribution of the engagement on 3 blades.
