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

The whole transaction, from ordiering to delivery to leveling my spoilboard

This is my favorite flattening bit hands down. I use it in my CNC machine as well as in a custom built router sled. It leaves very slight tool marks, that disappear almost instantly when you go over them with an 80 and then 120 grit sand papers.

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.

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

Works great good value!

Cuts good, gets a little hot but not too bad. It cuts epoxy well.

I love this bit. It cleans materials without leaving any marks whatsoever. I bought this one after wasting my time on another bit for half the price. This is still a very affordable, high quality bit. I will buy more of this one when needed.

I have a Shapeoko 3XXL and needed a bit to clean up the spoil board. The Whiteside is simple to use. I emailed Whiteside support and they provided the feeds and speeds to use. I have a lot of Whiteside bits and love them all.

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.
