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

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.

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.

Bought this to flatten cutting boards and hardwood boards with a router sled and a small plunge router. Works great so far as a substitute for a planer. Leaves some tool marks, but they sand right out.

You just cannot go wrong with Whiteside bits. I try to use them almost exclusively.

This bit did a great job resurfacing the spoilboard on my CNC. In the photo you can compare the before (inside) and after (outside edges). Surface was completely smooth to the touch, and no tearout on the edges.

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

I bought this bit to surface my CNC wasteboard. It did a wonderful job. What impressed me most was that I had 6 steel bolts holding down my wasteboard. The bolts were set below the surface of the wasteboard and I thought that I had enough clearance to cut away 2mm off the top. I was wrong and the bit ran over 4 of the 6 bolt heads. It wasnt intentional, nevertheless I didnt stop the job as I wanted to see if the bit would hold up. Every time it ran over a bolt head, I would hold my breath as sparks shot all around the dust shoe. After the job finished, the bit still looked great. I will definitely buy this again.

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.

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.

I bought this to flatten the spoil board on my cnc machine. It works well for this purpose.
