> 3 dayThis is well made, every bit as good as the more expensive Freud and Rockler bits I own. It comes in its own plastic case that closely matches the size of the bit for easy storage. It may seem trivial, but I store my bits in their original packaging, and the cases on Freud bits huge, so much bigger than the bit they hold, this case is perfect for how I like to store my bits. I haven’t used it enough to speak on its long term durability yet, but there are no red flags yet as far as the cut quality or craftsmanship is concerned. Recommended.

> 3 dayAt this price level I havent been able to find anything that compares to the quality they provide. They are well packaged, hold an edge well and are my first choice when I need to replace a bit. Ive got the 1/4, 1/8, 1/16 and theyve all just been fantastic. Im a pretty new user in the CNC world and Im not always dialed in on my speeds and feeds and Ive found these to be very forgiving for me. Highly recommend!

> 3 dayOrdered three bits and had them delivered today. The solo compression arrived flawless. The two pack of 1/16th bits came with one bit having the top busted off. Not sure how to contact the seller, but if I can get resolution I will update this review

> 3 dayI 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.

UP Cut BitUp-cut bit leaves a smooth bottom edge but a rough top edge. The up cut is better at evacuating chips, Ideal for mortise and tenons, grooving, slotting or routing deep blind holes. It performs faster cutting while pulling the chips up. |
Down Cut BitDown-cut bit leaves a clean top edge but a rough bottom edge. It is great for cutting shallow dados, rabbets, and visible slots. When cutting dados or grooves with a down cut bit, be sure to slow the feed rate to allow more time for chip removal. |
Compression BitCompression bit cut both top and bottom cleanly, Its spiral action pulls both sides into the center of the bit where it ejects out of the side. Through cuts in harwoods, softwoods, plywood, melamine, and other veneers |
