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

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

Personally, I believe they are way better than the ones that cost twice the price!!!

Ordered 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

At 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!

Used with dewalt dwp611 router.... only way it cut was if depth was 1/8, and even that burnt the wood... had to go VERY slow. My cheap yonko bit performed 1000% better than this on same material (particleboard with 1/16 veneer top)... tried different speeds of router - all same result. would return if it didnt look like picture after 5 cuts.

First use on a simple cut of maple, the bit snapped into two and ruined a good piece of maple. I bought 10 of these bits and will be returning them if I lose one more of them. It’s disappointing.

Nice as most better I dont know price was right Shipping was on time its my back up used it twice like it in plywood down cut

I picked up this item not knowing much about it. I found out REAL quick it was not very durable. Within the first 5 minutes of using it it broke. I returned it to amazon and got a replacement. Well it wasn’t a fluke. The replacement did the same thing. Will not be buying another.

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.
