Why Choose Spiral Router Bits Instead of Straight Bits?
- Spiral router bits combine a shearing action with an augering action for chip clearance. This dual action not only produces a clean and accurate cut but also efficiently clears chips from the cut area, enhancing the overall cutting experience.
What is Up-Cut Bits?
- Features: The ‘Up-Cut’ shears from the bottom up pulling chips from the bottom up thus allowing deeper penetration and rapid cutting with less stress on the tool.
- Applications: Best used in applications requiring clean finishes on the bottom surface, like grooving or deep cutting.
- Considerations: Risk to Top Surface: The upward action may damage the top layer, making them unsuitable for projects where top appearance is critical.
What is nACo Coating?

nACo, or nano-composite coating, is a micro-thin ceramic coating applied to cutting tools. Zahyox X-Series bits feature a nACo coating with extreme hardness and heat resistance. With a blue-tinted coloring, nACo enhances their performance and durability in router tooling.
- Sharpness Retention: Maintains cutting edges razor-sharp for precise and clean cuts.
- Reduced Friction: Features an extremely low friction coefficient of 0.25, minimizing tool wear and facilitating smoother operations.
- Heat Resistance: Can withstand up to 900°F, protecting tools from heat damage during intense cutting tasks.
- Enhanced Durability: Delivers a hardness of 3800 HV, which increases resistance to wear and extends 3 times longer tool life.
