Specially designed for 2D and 3D CNC profiling and carving in plastic & wood with CNC machines. The high-shear Flat bottom tips cut Smooth 2D and 3D contours with reduced stepping while the proprietary spektra 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. Some of Amana Tool carving tools, as you can appreciate have a very small diameter therefore any material chip-loads need to reflect that small size. It can however withstand RPM up to 60, 000 RPM. A directed air-blast to keep chips away along with cooling the tool and work piece are always welcome, #46292-K, (D) diameter: 1/8, (a°) angle: 0.10°, (b) Cutting height: 1-3/32, (D) shank: 1/4, overall length (L): 2-1/2, Type: flat bottom, naco ceramic coating, flutes: 4, 46292-K CNC 2D and 3D carving Flat bottom 0.10 deg angle x 1/8 dia x 1-3/32 x 1/4 shank x 2-1/2 inch long x 4 flute solid carbide Up-cut spiral spektra extreme tool life Coated router bit
