Available in the UK from Hertfordshire-based Floyd Automatic Tooling (www.floydautomatic.co.uk), the latest addition to the CrazyDrill range from Mikron Tool will be introduced at EMO 2019 (Hall 3 Stand H11).

The new CrazyDrill Cool SST-Inox, which will be demonstrated live, incorporates internal coolant ducts and an innovative geometry and coating technology for the machining of stainless steels, nickel-based super-alloys and CrCo alloys.

With process stability guaranteed, it has been significantly simplified and stabilised for the processing of small diameters as well as deep bores.

The range includes through-coolant drills in six different working lengths that include 6xD, 10xD, 15xD, 20xD, 30xD and even 40xD.

For machining holes with diameters between 1 and 2mm, the maximum depth available is 20xD. From a diameter of 2mm, the entire range is available up to a diameter of 6mm. In addition, there is a short pilot drill for a maximum bore depth of 3xD.

Markus Schnyder, head of Mikron Tool International, said: “For many years, our customers have been reaching the limits when drilling stainless steel.

“The process was not stable, and it was too slow, so machining was extremely expensive.

“We wanted to find a solution; the development took us several years, and we depended on a close co-operation with our partners, which included the use of the right blank material and a truly efficient coating.”
