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

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

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

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

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.

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.

I made a router sled and used this to flatten a hardwood /epoxy river table. I did get some burning but im chalking it up to user error and running it too deep. I stopped to clean the blade edges a few times and that was helpful

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.

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.

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

Surfaced a solid hardwood cutting board with this that was made of Walnut, Ambrosia Maple, and Purpleheart wood and it went to work without a single issue. I will be ordering more of this one when I need to replace it for sure and wont think twice about it!
