Amana Tool Solid Carbide Spektra 4-Flute Up-Cut Spiral CNC Carving Router Bit, Flat Bottom 0.10° Angle x 1/8'' Dia. x 1-3/32'' Cutting Height x 1/4'' Shank x 2-1/2'' Long

Specially designed for 2D and 3D CNC carving in plastic and wood, these bits feature high-shear ball nose tips for smooth contours with reduced stepping. The proprietary Spektra coating (applied by the PVD/physical vapor deposition coating process) reduces friction and heat buildup for exceptional durability and sharpness. Due to their small diameters, chip loads and feed rates should be reduced, and a blast of air to keep chips clear will improve performance. Withstands up to 60,000 RPM. For plastics, a suggested starting spindle speed might be 18,000 RPM, but the programmer will need to experiment and adjust to find an acceptable finish.

Features:

• The perfect bit for 3D carving, deep profiling, modeling, pattern making, signmaking, mold making and more
• Spektra™ bits feature a micro-thin nACo ceramic coating that prevents high heat and oxidation for enhanced sharpness, durability and cut quality
• Hardness tested at 4,500 Vickers—up to 2.5 times that of uncoated bits
• Blue color dissipates immediately upon use, but nACo® nanocomposite coating will not wear off
