KREFELD™ Extreme Tool Life Coated Signmaking CNC Router Bits are crafted from a specialized carbide with an advanced nACo® nanocomposite coating, designed to significantly extend tool life.

Specially designed for 2D and 3D CNC profiling and carving in plastic, aluminum & wood with CNC machines. The high-shear ball nose tips cut smooth 2D and 3D contours with reduced stepping while the proprietary ZrN coating (applied by the physical vapor deposition coating process) provides high resistance to wear, sharper cutting edges, extended tool life and less friction and heat buildup.  It can however withstand RPM’s up to 60,000 RPMs. A directed air-blast to keep chips away along with cooling the tool and work piece are always welcome.

Tools are manufactured with high balance that allows them to run up to 60,000 RPMs. Adjust your chip load and feed rate accordingly.

Key Benefits :

• Enhanced Edge Retention: A micro-thin ceramic layer helps maintain sharpness and reduces friction, ensuring high-quality cuts.
• Superior Heat & Oxidation Resistance: Prevents damage from excessive heat, preserving cutting performance.
• Long-Lasting Protection: Though the blue hue fades with use, the coating remains fully effective.
• Extreme Hardness: With a hardness rating of approximately 4,500 Vickers, it offers up to 2.5 times the durability of uncoated bits.
