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

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.

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.

I bought this bit to level and flatten some live edge rounds. I made a special table with adjustable rails and a trough to run a router back and forth across the rounds. The bit worked perfectly in my setup. My only regret is that I probably should have bought a wider bit to minimize the number of passes.

Great price. I recently bought a CNC machine and wanted to surface my waste board. This bit was exactly what I needed and within my budget.

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 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.

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.

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.

Good bit, cuts well for 1/4 great for the price. Rough slab 3 to 2 no problem

Bought this to flatten boards to wide for my jointer and for end grain cutting boards. Works great
