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 Compression (Up-Cut & Down-Cut) Bits
- Features: Compression bits combine the features of both up-cut and down-cut bits. The top part of the bit is designed to be down-cut, improving the top edge finish, while the bottom part is up-cut, enhancing the finish on the bottom side of the material. This up-cut down-cut action is what leaves a sharp, clean edge on both edges of your workpiece.
- Applications: The preferred bit for cutting laminated materials or any situation where both sides of the material are visible and require a fine finish.
- Considerations: To fully benefit from a compression bit, it's crucial to make the initial cut deeper than the length of the up-cut flutes to prevent any tear-out or chipping on either side of the material.
What is nACo Coating?

nACo, or nano-composite coating, is a micro-thin ceramic coating applied to cutting tools. ZahyoX PRO-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.
