FivePears Up&Down Cut Compression Spiral Router Bit for CNC, 1/8 inch Cutting Diameter and 3/4 inch Cutting Length 1/4 in Shank Carbide End Mill Router Bit for Wood Carving Engraving Grinding Grooving

Normally after 10-20 sheets of parts, most bits have chipped tips. This bit has gone 92 sheets so far and still looks great. This after cutting about 20 parts per sheet in 3/4 ACX.

I wanted to make slotted holes in oak. These pieces were an inch thick and for holding a table top on. The bit cut clean, fast and held up for multiple holes. Ill be buying more from this company.

I got the 1/16 bits to try routing some freehand designs (no CNC) and they have worked beyond my expectations. Given the small bit size, I anticipated that they would have a relatively short working life. Ive used these bits on around 15 (each) projects for designs ranging from a few inches to a couple feet on a variety of materials (mostly red oak) and they still cut just as well as they did on day one with very little maintenance. I clean the bits after each use but they have needed no sharpening. I can only imagine how much better they would be in a CNC. Highly recommended.

I liked how clean it cuts. I ise this on a cnc for cutting out letters and pockets in wood.

I have a Shapeoko 4 and am using this bit to cut 1/4 and thinner plywood in one pass. You want a compression bit to be engaging enough of the cutting surface that you get the benefit of an upcut for the underside and a downcut for the top surface resulting in a clean cut on both surfaces. It being 1/8 means I usually an doing a larger contour cut first to hog out material and then cleaning up with this, but it works well and is a more affordable option than some of the pricier bits.
