KREFELD - CNC 2D and 3D Carving 0.10 Deg Straight Angle Ball Tip 1/2 Dia x 1/4 Radius x 2-1/4 x 1/2 Shank x 4 Inch Long x 3 Flute Solid Carbide ZrN Coated

 (Diameter) → 12.7 mm  (Radius) →  6.35 mm  (Shank) → 12.7 mm (Length) → 101.6 mm   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. a°) Angle 0.10° (D) Diamete
