Whiteside 6210 CNC Spoilboard Surfacing Router Bit, 1/4 Shank

This is my favorite flattening bit hands down. I use it in my CNC machine as well as in a custom built router sled. It leaves very slight tool marks, that disappear almost instantly when you go over them with an 80 and then 120 grit sand papers.

Works great, makes flattening my projects so much easier

If youre looking for a great router sled bit look no more you have found it....I kept putting off buying one for so long but will buy only Whiteside bits from here on.

This bit did a great job leveling the spoil order on my CNC router table.

Unfortunately this bit just didnt last long before it started burning the surface of my projects. I used this to surface pine boards ony CNC and it worked great at first but it wasnt long before it started having issues.

This bit is a very nice bit, but needs cleaned frequently. Im picky and clean this after almost every use if there is a build up of pitch on it. Used mostly for flattening stock in my CNC.

Did a great job leveling my 24 X 49 particle board vacuum chuck spoil board. I used a spindle speed of 12,000 RPM, a feed rate of 80 inches per minute, a .010 depth of cut and a .4 step over on this 1 router bit to make a smooth surface thats free of ripple that might be caused by an out-of-tram spindle. It took a little over 30 minutes to level the spoil board and it made a lot of very fine dust. The CNC router is completely enclosed so this wasnt a problem, but if you use this without a full enclosure, youll have fine dust flying all over your shop and you dont want to breathe that fine dust.

I use it for wood and epoxy and it does the job great! still hasnt gotten dull on me. You can never go wrong with white side

I made a router sled and used this to flatten a hardwood /epoxy river table. I did get some burning but im chalking it up to user error and running it too deep. I stopped to clean the blade edges a few times and that was helpful
