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

Used this to cut a table top from a elm tree block of wood. Cut this without any problems and the bit is still sharp.

Great product, used it on cnc machine , Great value for the money

Works great good value!

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.

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

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.

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.

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!

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.
