For the drilling of ultra precise holes, Floyd Automatic Tooling has now launched the new CrazyDrill Flex series of drilling products from renowned Swiss precision manufacturer Mikron Tool. The new range of solid carbide drills are extremely flexible and therefore suitable for deep hole drilling up to 50XD.
The new CrazyDrill Flex is manufactured from a high grade carbide with an innovative geometry that makes the new drills extremely flexible and accurate. These attributes are advantageous when alignment errors occur, especially in applications with highly productive sliding head lathes, multi-spindle machines and transfer machines. The CrazyDrill Flex can effortlessly compensate 40% of its diameter thanks to its flexible centerpart that prevents breakages and provides flexibility only previously available with HSS drills.
The special tool geometry makes it possible to drill even in the instance of drill alignment errors. The CrazyDrill Flex eliminates errors quickly without cutting edge breakouts to guarantee reliability and extended tool life. The CrazyDrill Flex has been developed with a host of innovations such as a special tool tip geometry that reduces feed force by 50% to permit maximum drilling speeds and minimal heat. The flanks of the drill incorporate an edge protection system that prevents the cutting edges from breaking when drilling holes at high speeds and feeds.
The newly developed drill point is complemented by a unique chip flute geometry that creates short chips that can be evacuated with ease. Beyond the drill flutes is the flexible centrepiece. This flexible shank prevents breakages caused by alignment errors enabling customers to achieve the staggering 50XD drilling depth. With a precision ground 3mm shank, the customer can be confident that run-out is eliminated. The combination of these attributes give productivity that is 8-10 times faster than single flute gun drills whilst minimising lateral forces and run-out for exceptional positional accuracy.
The new CrazyDrill Flex is available in 20XD, 30XD and 50XD with a range of FlexPilot drills also available for drilling at 3XD with diameters from 0.1 to 1.2mm in 0.01mm increments. The CrazyDrill Flex is available with two coating types that are differentiated by name, the CrazyDrill Flex Steel and the Flex Titanium. The Flex Titanium has been developed for the drilling of tough and long chipping materials such as copper and titanium alloys whereas the Flex Steel is a more diverse drill that is capable of drilling alloy and non-alloy steels, cast iron, aluminium alloys and brass.
The CrazyDrill Flex 20XD drills are available in diameters from 0.1 mm to 1.2 mm with cutting lengths from 2 to 24mm whilst the 30XD drills are available with the same diameters but with a cutting depth from 3 to 36mm with overall lengths from 40 to 70mm depending upon drill diameter. With regard to the exciting new 50XD drills, the diameters vary from 0.3 to 1.2 mm in 0.1mm increments with drilling depths from 15 to 60 mm with overall lengths from 53 to 95 mm.
The CrazyDrill Flex incorporates three coolant channels in the drill shank to optimise tool life, machining performance and evacuate swarf. The Swiss precision specialists recommend using a cutting fluid at a minimum pressure of 10Bar to optimise performance.
