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?

What is Compression (Up-Cut & Down-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.

    Good bit performs as promised

    The media could not be loaded. This bit comes in a nice tube storage case, and was sharp and ready to use. Have used a few times these past weeks and it has performed as promised. So far have only tried it out on hardwood and plywood, but have had no complaints.

    A very high quality CNC Router Bit (An up-cut bit for a clean bottom)

    The product received is exactly as described on the website: It's an up-cut CNC router bit of the dimensions 3/8-shaft, 2 cutting length, and 3/8 cutting diameter. An up-cut bit like this has a spiral orientation such that it results in a cleanly-cut bottom side of the cut, but possibly producing rough edges at the top, where the pulling-up cutting action tends to pull up wood fibers.It's extremely sharp, and appears to be a very high quality bit. 5 stars.

    Great bits! Finish is what I expect from an up-cut bit

    Impressed with this bit so far - high quality machining, consistent coating, razor-sharp, and leaves a finish to cuts that is what I expect from an upcut bit of this caliber.As you can see there is just a TINY bit of "fuzzy" on my piece of quited hard maple I used as a tester - wood that is VERY prone to tear-out.Definitely recommend!

    Great for woodworking with a 3/8 plunge router

    I use this for cutting mortises in my plunge router. It cuts beautifully and the added length means I can cut a 2 deep mortise with a few passes. It is very sharp and makes exceptionally smooth cuts. The spiral pulls the wood chips out well so you can see what you're doing. Highly recommended!
