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

Works great good value!

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

Works as intended, and cheap enough to warrant keeping around. I use it for surfacing MDF wasteboards only, wouldnt use it to surface my actual workpiece I dont think.

I bought this bit to level and flatten some live edge rounds. I made a special table with adjustable rails and a trough to run a router back and forth across the rounds. The bit worked perfectly in my setup. My only regret is that I probably should have bought a wider bit to minimize the number of passes.

Once I surfaced my spoilboard I was able to properly tram it. Then I surfaced again and now all my cuts are dead on flat as the should be. This is a got to item!

It came in quickly - It looks like it will do the job well - I havent used it yet, but its as described, and It should work very well.

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 bought this for stock and spoil board surfacing on my CNC router. This is a very well-made product, and worth the money. My only caveat is that, if you plan on using this on a large piece (my spoil board is 3 x 4), it may be worthwhile to buy a larger bit. A 1 surfacing bit will get the job done a lot faster. Be wary of Big Box MDF when using this bit. Ive twice encountered staples buried in the middle of MDF. The most recent encounter did some damage to this bit.

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.
