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

I bought this to flatten the spoil board on my cnc machine. It works well for this purpose.

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

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.

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.

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.

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.

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!

Bought this for surfacing my spoil board which was great. I don’t have a planer in the shop so decided to try planing some mahagony with it and that worked wonderful as well. Whiteside makes wonderful products at a great price point.
