For the price of this product, the sharpness and durability were satisfactory. I reamed a few 1/4" holes in 3/16" thick strip of steel and these bits got the job done quickly. Towards the end of the work it looked like the bits were wearing out, but that could tire me out. π. I'll update if anything important happens. This is definitely a good thing to buy.
