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

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!

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.

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.

Packed well the blades were sealed to keep them sharp. SSI far the durability has held up, Ive only used it 3 times. Still has a sharp edge.

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.

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.

Ive used this bit several times to flatting a few slabs. I wanted a slightly smaller cutter so I could use my palm router and not overload it. This bit works perfect and leaves a great finish on my slabs. It took 2 passes of sanding after to get a great finish.

Works great, makes flattening my projects so much easier

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.
