🔧 SainSmart Genmitsu 10Pcs Router Bits 0.8-3mm Review

So yes you will get a set of different sized end mills of average quality but don't rely on what the box says, the actual diameters are not to match. It's okay if you take a pair of calipers with you and enter the correct measurements into your program, which calculates the tools' path. The tips could be sharper, but if you're mostly working with wood and making shallow cuts, you should be fine. Next time I'll probably spend more money to get better quality beats.

So far they have performed great when cutting wood. Just make sure your channels and speeds are correct. If you run them too fast they break, if you run them too slow you create friction that heats them up until they wear out very quickly. Even the world's most expensive end mills can fail due to operator error. I've had good results cutting hardwood with a 1.4mm bit with SFM: 141, chip load 0.005 and depth of cut 0.0157 (4mm). I probably wouldn't recommend cutting metal with it, but haven't…

I received a set with a CNC machine first and have been using it for 3 months. I cut something with them almost every day, mostly plywood, and they are durable. The bits are still in great shape and cut cleanly. I know they will wear out eventually because I use them so much, but so far they show no signs of slowing down. I was so impressed I ordered a second set as I saw they were very good value for money on Revain. The kit contains most of what you need for a CNC machine with 1/8 collet…
