Product catalog summary

Overview
The document details the Mikron Tool drilling concept, focusing on the CrazyDrillTM Cool system for deep-hole drilling. It emphasizes the system's advantages, characteristics, and recommended procedures for optimal performance.

Specifications
- The CrazyDrill system is designed for drilling deep holes up to 15 times the diameter (15 x Ø) in sizes ranging from 0.75 to 6 mm.
- Constructed from solid carbide alloy, available in both coated and uncoated versions.
- Standard lengths are offered, with special lengths available upon request.

Drilling Concept
- Utilizes a two-stage principle: CrazyDrill Pilot or CrazyDrill Crosspilot for centering and pilot hole creation, followed by CrazyDrill Cool for achieving maximum depth with minimal pecking.
- Allows direct drilling with an inclination angle of up to 60°.

Benefits
- Enables maximum drilling speeds and feeds.
- Reduces run-out and extends tool life due to pilot drilling.
- Can replace traditional deep-hole drilling methods.
- Suitable for machining difficult materials.

Cutting Parameters
- Provides guidelines for cutting speeds and feed rates based on material type, including low-alloy steels, high-alloy steels, and titanium alloys.
- Recommends cutting oil as a lubricant, with alternatives like water-based coolant or minimum quantity lubrication.

Recommendations
- Use cutting oil for optimal results, with a filter quality of 10 microns for diameters < 1 mm and 20 microns for 1.0 – 2.5 mm.
- Chip removal guidelines vary by material, with specific instructions for depths up to 6 x Ø, 10 x Ø, and 15 x Ø.
- High-precision collet systems are recommended to minimize run-out.

Conclusion
The CrazyDrillTM Cool system provides a high-performance solution for deep-hole drilling, enhancing productivity without the need for costly manufacturing systems.
