Festool tools

An impact-resistant and user-friendly drill packaging is absolutely necessary for CrazyDrill Cool XL. Mikron Tool offers all tools of the CrazyDrill Cool XL family in a high quality, single package.

For the use of the CrazyDrill Cool XL and CrazyDrill Pilot, Mikron Tool has defined a fast and reliable procedure which achieves optimal drilling results.

Mikron Tool has an international team of cutting technology experts who  are pleased to answer your questions (how to use a drill, tools, machines, tool holders, cooling, machining process…).

In the industry of metal work tools, shorter processing times are always in high demand. At the same time, the requirements to the manufacturing precision and the process reliability are extremely high. In order to fulfill these requirements, the "machine tool – spindle – tool – tool holder" system need to be considered as a whole (see additional info).

The tool tolerances guarantee the hole quality (no measurable transition from pilot to follow-up hole) as well as the stable machining process (no jamming).

The overview of the cutting values table according to material group, material type, hardness degree and tensile strength, material number, DIN and AISI/ASTM/UNS permits quick determination of the parameters to be used.

For the drills of 20, 30 and 40 x d the CrazyDrill Cool XL needs to enter the hole and be retracted from the pilot hole at reduced speed. For the CrazyDrill Cool XL 15 x d the afore mentioned procedure is not necessary.

Mikron Tool has determined the ideal cutting parameters (drilling speed to tool life ratio and process reliability) when using CrazyDrill Cool XL and CrazyDrill Pilot respectively CrazyDrill Crosspilot. These are listed in the cutting data tables according to drill diameter, drilling depth and material to be machined. The detailed cutting data tested by Mikron Tool, such as cutting speed Vc, feed rate f and drilling impact Q, permit a quick and secure machining.

The deep-hole drill CrazyDrill Cool XL perfectly matches with the program of CrazyDrill Pilot (pilot drill or short drill). Pilot drilling with CrazyDrill Pilot or, on inclined surfaces, with CrazyDrill Crosspilot constitutes the base of accurate deep-hole drilling and stable machining. The pilot drill yields a high degree of position accuracy due to its short and sturdy design. In addition, the follow-up drill (CrazyDrill Cool XL 15 to 40 x d) is guided cylindrically by the pilot hole, thus guaranteeing perpendicularity and alignment accuracy.
