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

Good price. Cut through my waste board to resurface it with no problems. Ran it .1 DPP @ 100IPM.

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.

Ive read stellar reviews and have used this bit for a handful of projects that were spread out over about a month. Facing my spoilboard, and a couple MDF & Birch wood projects. I tried 1 epoxy inlay project and the bit was actually ripping out epoxy along each pass. This bit worked great at first. Not anymore. The edges of the but are not quite sharp anymore. Theyre actually polished looking, which lens me to believe that the carbide grade isnt that great and/or the relief grind is shallow. First off, I know for a fact that the relief being angle on this bit is very shallow. In the machining industry, relief grind is generally @3 degrees. This does not appear to be the case. The cutting edges are polished. One usually only seen this when machining extremely abrasive materials such as glass filled composites, titanium, or nickel based alloys. I highly recommend paying the extra money for insert bits.

Bought this for surfacing my spoil board which was great. I don’t have a planer in the shop so decided to try planing some mahagony with it and that worked wonderful as well. Whiteside makes wonderful products at a great price point.

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.

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.

I will admit, i just got this bit and Ive only flattened one walnut slab.. that being said, cuts like butter. I would be extremely surprised to find a better flattening bit at this price range that can perform as well. Awesome product!! Would love to try the 6220 when i can.

I just purchased a cnc router and needed a surfacing bit for my wasteboard. After doing a little research and asking some friends, they suggested this Whiteside bit. There are other, more expensive bits out there but since Im just starting off, I thought Id give this one a try. Worked very well for my needs and left a very smooth and level surface. Surfacing MDF produces a ton of dust so make sure you have a decent dust collection system or enclosure and of course, wear a mask when working with MDF. For the price and quality, I felt it was a solid buy.

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