The Router Bits: The Magic of Compression Router Bits

Compression Router Bits:
Video: The Magic of Spiral Bits

In this video, Patrick takes us through the benefits of compression router bits. Be sure to watch right through to see these babies in action and how they can work for you...
Rather than offering upcut and downcut versions, the pattern following bits have a compression (combination up and downcut) profile which ensures optimal, crisp and clean edges both top and bottom of the material.

Nice review, and pretty in-depth explanation of the different bits.👍
Cheers, mate 👌

Hmm... I still use the old style 2 edge router bits and they cut better than what i see in this video as long as they're kept super sharp. I use a set of Grobet USA diamond needle files to keep my router and forstner bits cutting perfectly.

My issue with these, and spiral bits, is sharpening.

I like spiral compression bits (and chip breaker bits) but for $80-$200, it becomes a throwaway once it starts to dull.

What about ideal bit for trenching where we still need top and bottom to finish nice.. whats best bet in that scenario? (undermounted sink in oak butcherblock worktop for example with 5 passes)

[lordRW]

its not about the direction of the bits its the direction of the cut, its like having a knife pressing up on the wood its the cutting edge that is pressing the wood up making the end grain come up, the sharper the bit the less this shows, so you put a sacrificial plate on it so you have force holding the end grain in place and it doesnt get pulled up by the knife edge.

Nice bits, look like a bugger to resharpen though!
