I bought some lathe tooling from Banggood. I had a problem with a tool holder for WNMG inserts. Apparently the maker had mis-labeled the packaging. I ordered a RH turning tool but got a left hand. It came with 10 inserts. I sent photos and Banggood sent me a replacement. Another LH tool in a box marked RH. It came with 10 more inserts. I considered the price I paid was reasonable for the 20 inserts and did not pursue it further.
I bought insert type threading tools, internal and external, from Banggood and am satisfied.
I bought a boring bar for WNMG from Banggood and am satisfied.
I bought inserts MGMN200, APMT1135, APKT1604, SEMT13 and am satisfied with all.
I bought insert type end mills for APMT1135 in 3 sizes. They listed them as boring tools. Each tool was about 8" long so I cut down the shanks to a more useful length. Except for the excess length I am satisfied with them.
I bought a USB microscope from Banggood that was junk.
That is my experience with Banggood.
I would not buy face mills I saw on their site because all I saw had aluminum bodies. If I found some with steel bodies I might consider buying them.
