Spiral Flush-Trim Router Bits，Solid Carbide Flush Trim Router Bit 1/4-Inch Shank Spiral Flush Trim Up Cut from TACKPRO (1/4 Shank Up-Cut)

Using this bit in a router table with adequate dust collection. The top cut is nice and clean, but the underside cut is ragged. Even with the dust collection, it throws a lot of these shredded wheat shavings around. Causing me to have to stop and vacuum after every cut. Not great for time management. More expensive bits do not do this. For the money, it is sharp, it does cut and it gets the job done, but it adds time when you have to sand edges and clean up the mess.

Great router bit did everything I expected plus more

Ive broken 2 of these bits cutting 1/4 aluminum.. Id like to know if theres a warranty for replacement on both of them??
