Spoilboard resurfacing is actually a very common thing that has to be done with new CNC routers, as well and reconditioning the surface after it has been cut into many times.

To read more about what a spoilboard is, read this article or watch this video about surfacing bit feeds and speeds, or this video about how a surfacing flattening bit can be used.

You'll find the surfacing bit is a necessary bit almost immediately after you get your CNC router. This is because most spoil boards (a.k.a waste board or spoiler board) are not parallel to the router motion. So you need a flattening bit to resurface it.

This 1.5" diameter surfacing bit is made specifically for hobby and semi-professional CNC'ers. It is made to get effective clean-up on your spoilboard in one pass at high feed rates.

This 1-1/2 inch surfacing bit, designed for super-smooth cuts, is used in your CNC router to surface or flatten your CNC router spoilboard (also called a spoiler board, or waste board), as well as slab flattening, and prepping your CNC router project surfaces. The surfacing bit for CNC routers is a super-important bit to have.

Receiving your new CNC router is exciting. One of the first tasks you will want to do is level up your spoilboard for 2 reasons.

What's more significant is the 4-flute design. Most surfacing bits only have three flutes. This allows for better finishes with faster cutting speeds. And more flutes means extended tool life, as well.

Used this bit for the first time in the same application I used my Carbide 3D MdFly surfacing bit, and this bit left burn lines on the wood.

It does a nice job on planing down my Hardwood cutting boards. A word of advise, when using a Inventables X-Carve Pro, set your depth to .02. Otherwise it will seize the machine and you will need to unplug the machine to reset it. It took a couple times to figure that out, but otherwise it planes the hardwood end grain down smooth with less sanding.

This 1-1/2 inch surfacing bit, designed for super-smooth cuts, is used in your CNC router to surface or flatten your CNC router spoilboard (also called a spoiler board, or waste board), as well as slab flattening, and prepping your CNC router project surfaces. The surfacing bit for CNC routers is a super-important bit to have.

What makes the 1-1/2" surfacing different? Typical surfacing bits for CNC routers are 1" diameter. They work fine. However, they do take longer to do your surfacing work. With the 1-1/2 inch surfacing bit, and a stepover of 90%, the surface work can be done in half the time, and you'll have a much smoother finish due to the broad cutting area.
