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.
The IDC Woodcraft 1.5 inch surfacing bit works with all brand CNC machines with a 1/4" collet.
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.
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.
