Genmitsu 10 Pcs 1/8" Shank V-Groove CNC Router Bits, 10 /15 /20 /25 /30 /40 /45 /60 /90 Degree Set, Nano Blue Coat Conical V-Bit, Engraving Tool for CNC Signmaking Carving Lettering 2D&3D Sculpture

Overall I'm impressed with these bits. The value far exceeds by expectations. Based on some other reviews, I was expecting sub-par performance from these bits. However, after 3 jobs I see great results and will continue using them. 10 bits at this price is a tremendous value. Update: After some additional time with these bits, I've noticed that they have an issue with clearing chips while cutting hardwood in particular. When cutting a 5mm deep v-channel in maple, the resulting channel is hard packed with dust/chips. Adding an additional finishing pass helps marginally, but there is still lots of manual work to clean out all the chips from the cut. I still recommend these bits since they are great for the price, but know that more cleanup work than expected may be needed when cutting some materials.

excellent product, I do recommend high quality

Exactly what I needed and I've actually mastered what I was trying to do with them! When and if I ever need these again, I'll be back to buy this exact bits.

Pretty much the best bang for the buck if you are working with wood on a small CNC. I don't think I would recommend anything more robust than aluminum with these, and even that would need to be a very shallow pass.

great assortment of bits to do different types of carvings on cnc machines. made of durable materials allowing the bits to last for longer periods of time depending on the wood being used

Nice sharp bits. Would buy again.

These little 30 degree bits are great I use them on hardwood like Purple Heart and African Padauk that is very hard and the engraving that I do takes 3 to 4 hours they stay sharp and make a very clean cut. You will absolutely love what they do and the money you save is crazy. Don’t pay attention to the bad reviews I’ve been doing woodworking for 35+ years and have tried them all I’m very happy with the performance of these bits.

Maybe my settings are wrong, but they don't cut any better than the cheap HSS ones.
