Extra long High Performance Drills

CrazyDrill Cool XL for deep hole drilling With the new CrazyDrill Cool XL, the engineers from Mikron Tool have developed a brand new deep hole drilling program for depths up to 40 x d. The CrazyDril Cool XL due to its design produces short chips in al materials and in each phase of the drilling process. An undesired coiling of chips does not occur. High quality carbide alloy of the latest generation and the most precise grinding technology assure that this new product ine meets the strictest quality requirements. With a coating, developed especially for CrazyDrill Cool XL, excellent cutting conditions...

Recommendations for optimal results Straight surface • Pilot hole with CrazyDrill Pilot • Hole depth approx. 2x0 • Guide for precision drilling with CrazyDrill Cool XL • Start coolant supply before entering the pilot hole Inclined surface • Pilot hole with CrazyDrill Crosspilot • Hole depth 1-2x0, depending on inclination (max. 60°) • Guide for precision drilling with CrazyDrill Cool XL • Start coolant supply before entering the pilot hole • Enter 1 -1.5x0 into pilot hole with feed Vf = 1000 • Enter 1 -1.5x0 into pilot hole with feed Vf = 1000 mm/min and reduced speed of 500 rpm mm/min and reduced...

Guidelines for cutting parameters Important: for drilling depths of 40 x 0, the cutting parameters have to be adapted to the used machine and the specific application! Please contact our tooling technology consultants for information and support. General criteria: These values are intended to represent approximate ranges. This data is indicative. Different conditions due to machine, spindle, working direction vertical or horizontal, coolant, etc. can influence the performance. Clamping equipment Cooling lubricant High-precision collet systems for minimal run out (T.I.R). Length presetting and...

The chip shape is crucial Perfect chips Critical chips The chip formation determines the success of deep hole drilling Speed and feed have to be tuned for the perfect chips. • Ball bearing steel 100O6 • Cutting speed vc 80 m/min • Hole quality: Mechanical Engineering: • Cutting speed vc 120 m/min Services that complete Mikron Tool supports our customers on the selection of suitable tools with respect to material and geometry, required tolerances and ideal operating parameters, and partners with them from the initial trials through mass CrazyDrill Cool XL can be reground and recoated which considerably...
