Technical Parameters

Product Applications & Uses

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty metalworking sectors, including automotive manufacturing, aerospace components, mold & die making, and heavy machinery production.

• High-Speed Deep-Hole Drilling: Specifically optimized for high-RPM setups where consistent hole accuracy and strict surface finish tolerances are required.

• Excellent Chip Evacuation: The internal cooling channels blast coolant directly to the cutting edge, flushing out chips instantly to prevent chip packing in 3D deep holes.

• Multi-Material Versatility: Ideal for drilling a wide range of challenging materials, including:

  • Carbon steel and alloy steels

  • Stainless steel (e.g., 304, 316)

  • Cast iron

  • High-temperature alloys

• Rigid Machining Centers: Perfectly suited for CNC machining centers, milling machines, and specialized drilling equipment utilizing thru-tool coolant capabilities.
