Anyone using a CNC router like the Shaper Origin will have plenty of CNC router bit sets to choose from. Fortunately, Shaper’s own Shaper Origin bits are premium cutters that rarely need replacing. Amana Spektra bits—with their lustrous nACo coating—are another option well worth your consideration.
Let’s see how they stack up.
Shaper offers three reliable and versatile styles of solid carbide Shaper router bits, all for use with their Shaper Origin:
This is a general-purpose CNC router bit for depths up to ¾” (¼” per pass). The durable, solid carbide shaft features twin cutting flutes that will pass quickly through even large panels. It’s the most common selection for all wood types from ply to hardwood.
Specs:
The narrower ⅛” Up-Spiral bit is your pick for cutting finer details. Like all of Shaper’s bits, it’s carbide cutting edges will remain sharp for a long time. Most Shaper Origin owners will want to keep both this bit and the ¼” size always on hand.
Specs:
As CNC engraving bits go, Shaper prefers a compact and simple bit with a V-style tip that enables you to cut fine lines in a range of materials without sacrificing durability with a thinner or more elongated design.
Specs:
If this is where you stop on your hunt for CNC router bit sets, you’ll do just fine. Shaper Origin’s bits are classic and dependable. With that said, the Amana Spektra CNC router bit set has a few neat perks worth considering.
Amana CNC Router Bits use a micro-thin ceramic “nACo” coating over the carbide tips to provide extraordinarily long-lasting sharpness and lubricity. The colorful hue fades quickly with use, but the Amana router bits retain their coating and properties long after the colors disappear. Your nACo-coated bits will perform with a 4,500 Vickers hardness ratingof solid hardness (up to 2.5X that of uncoated bits!). There are no finer bits for versatile and rigorous applications.
Amana Spektra CNC engraving bits use a triangular, flat-bladed tip for extra-fine carving and lettering at up to 28,000 RPM. The nACo nanocomposite coating gives the slender blade the heat resistance and nanohardness it needs to stand up to frequent use.
Specs:
This fine-tipped ‘down-cut’ CNC bit provides unparalleled smooth edges and clean cuts. It cuts down from the surface, but still clears chips from the cut with combined shearing and auguring action. It’s excellent on particleboard, plywood, melamine, laminate, and MDF.
Specs:
The ¼” Amana Spektra bit offers you a longer lifetime in abrasive material than the similar Shaper Origin bit—especially in double-sided melamine, CFRP, particle boards, and laminated or veneered material.
Specs:
No Amana Spektra CNC router bit set is complete without a flat bottomed bit with high-shear for precision carving. Use it for 2D and 3D contouring, deep CNC profiling, 3D millwork, and dimensional signage. The reduced friction and heat buildup of the nACo coating allows it to withstand up to 60,000 RPMs.
