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

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!

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 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.

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

Works as it should. Seems to be well built. Only used once so far.

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.

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

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

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.
