Amana tool 46424-K SC Spektra Extreme tool Life Coated Up-Cut Spiral Bal Nose 3/32 R x 3/16 D x 1/2 CH x 1/4 SHK x 2-1/2 Inch Long x 2 Flute Router Bit with High Mirror Finish

Spektra™ Extreme Tool Life Coated, Solid Carbide Up-Cut Spiral Ball Nose Router Bits for Superior Surface Finish, Excellent for Cutting Plastic, Acrylic, Solid Surface & PlexiglasAmana Tool’s high mirror-finish solid carbide up-cut spiral ball nose router bits are designed to eliminate tool marks that commonly appear when used with plastic and solid surface materials.  Due to the highly polished finish and unique tool geometry, the spiral ball nose router bit delivers superior surface finish of at least 28 Ra (roughness average) in various materials.  The up-cut router bits also eject chips up to help prevent chip out on the bottom of the material.   Constructed of special grade solid carbide, the Amana Tool spiral ball nose router bits last longer than traditional router bits and deliver superior cutting performance in materials including plastics and solid surface. The bits are ideal for use in a variety of applications spanning the mechanical, medical and woodworking industries.

With a brilliant distinctively-tinted coloring nACo provides additional improvements in four critical aspects of router tooling.nACo coating is a micro-thin ceramic coating which enables the tool's cutting edge to retain crucial sharpness and lubricity. This provides longevity and produces cutting results of the highest quality.Coating prevents high heat and oxidation which is detrimental to cutting tool performance.Multi-colored hues, while attractive, will dissipate upon use and yet coating will remain fully effective.nACo offers approximately 4,500 Vickers for impressive solid hardness on cutting areas of the tool, for an increase up to 2.5 times compared to uncoated bits.
