Frequently Asked Questions

Designed for leveling and cleaning the sacrificial spoilboard on CNC tables or router sleds. Wide diameter and multiple flutes ensure efficient flattening.

A ½" shank offers greater rigidity and less vibration compared to thinner shanks.

Replaceable insert bits (like Amana's with 4-sided knives) offer better longevity—cheaper over time versus replacing entire bits.

Absolutely—surfacing bits perform flat surfacing much faster than small end mills, significantly reducing runtimes.

Yes—but may still require sanding afterward for full smoothness.

Community reports describe dust clouds on “cosmic scales”—strong dust collection is essential.

Routers with 2¼ HP+, ½" collet, variable speed, and soft start are preferred. Examples: Porter-Cable 890, Bosch 1617 EVS.

Some recommend raising spoilboard height or using a shorter sled to compensate.

Yes—take shallow passes, reduce RPM, and keep bit moving to avoid burning.

Use appropriate feed/fine passes and larger diameter bits; users reported no ridges on 5×8’ table using 2.5" bit.

So far, it's been great!

I have several routers, only one is CNC. It happens to be one of the popular 3018 machines with and extended Y-axis, call it a 3037. I have a poplar board I've been using to make spoil boards. The W05011surfaced my latest spoil board very well. More importantly, it squared the spoil board to the spindle. This board had been through the jointer and thickness planer already, so it was already close and didn't take much to finish it. I haven't tried it on MDF because my dust collection system isn't great. I do like the fact that the cutters have 4 usable sides.AND it has extra cutters. It's going to be a long time before I need more. I'm not cutting deep. I'm only making sure the spoil board is aligned with the spindle. Out of curiosity, I also tried on a purple heart work piece. Again, not going too fast or cutting deep.It did very well on a 6" x 6" purple heart board. If you've ever worked purple heart, you know it can be difficult. I only took off 3/32". Yes, I did need a little denatured alcohol to clean the bit afterward. That was expected. If I find something not to like about this bit, I'll edit my post. At first glance, this bit works as advertised.
