Virtually every bit from China I found to have one or more of these issues...
to name a few...
poor QC... Can we say sucks here??? We are the QC department for them and you are pretty much on your own...
little or no CS at all...
poor balance... out of balance bits are hard on the router...
poor brazing.. you can ask my ear about that...
dull out of the package... this means they don't shear their way through the wood, they chop making for additional finishing time and materials.. tear out is a common thing for them...
softer carbide.. short production life due to dulling...
piss poor performance...
fragile.. carbide chipping/breaking when hitting a dense knot..
cutting edge came already chipped/serrated right out of the package...
shank diameters aren't as advertised...
two piece construction.. body to shank which during use would separate/break...now we have an out of control projectile on the loose...
same part number/same manufacturer/same profile... but one bit's profile to the next doesn't match..
bottom line, china was very expensive no matter how little was paid for a product from there... dangerous too.... this makes them expensive iven if they are free to you...
NOTE:
there are a lot of
NAME BRAND knock offs and counterfeits coming out of china...
something they're virtually infamous for...
You could buy another cheap machine and hope it's better, but as the saying goes, "Good ain't cheap and cheap ain't good."
