CrazyDrill Flex of Mikron Tool makes the drilling within the diameter range from 0.1 to 2.0 mm (.004” to .079”) possible with versions for steel, titanium and stainless materials (coated version for steel and version for stainless materials in fractional inches available). The straight connecting element (neck) between the cutting body and the shaft gives the carbide drill CrazyDrill Flex the length required for drilling deep holes up to a bore depth of 50 x d and makes it very robust. Thanks to CrazyDrill Flex, small and deep holes can be drilled quickly, precisely and in a cost-efficient manner on machining centers, automatic lathes or rotary transfer machines (instead of using a gun drilling machine). In the case of deep and small drilled holes, this extra-long drill guarantees a significantly shorter drilling time compared to the single-lip drill, the electro-erosion (EDM) or the laser method.
The flexible tungsten carbide (VHM) drill is not actually a specially designed drill for plastic, but it can also be used as for certain thermoplastic materials and plexiglass.
To achieve high position accuracy in deep-hole drilling, it is recommended to do a preliminary piloting / centering operation with the CrazyDrill Flexpilot (Steel coated or uncoated, respectively Titanium) for CrazyDrill Flex Steel and Titanium. These short drills for depths up to 3 x d, create a perfect position accuracy and cylindrical guidance for deep holes realized with CrazyDrill Flex and permit high drilling speeds based on their innovative drill geometry.
