amoolo Hex Shank Drill Bit Set 13Pcs Set 3 Pcs Free Premium 4341 HSS Titanium Impact Hex Drill

Hex drive drill bits are very handy as they so easily slip into many types of drivers, all with the 1/4" socket. These bits seem of good sturdy quality and with 16 bits in total, there's one for most every job. My only complaint was the packaging. When the order arrived several items were pocked in the same box, but the packaging for these bits had given up, and they were loose in the outer box. Otherwise the assortment was fine and a moment's sorting put them back properly in their container. Read more

I got these bits to use in drilling a hole in a crankshaft so that I could insert a locking pin. I was using a air powered drill motor. I was amazed at the speed that the bit drilled into the forged end of the crankshaft. I was dreading laying under the car for an extended time pushing on the drill. There was no problem. The drill bit into the crankshaft with very little effort and I was finished in no time. I might be that the bit is more prone to breaking due to its hardness but I did not have any breakage.

Sharp but slightly oversized, within spec for this price point. One problem is the flute design seems to have a problem clearing chips when drilling aluminum. I had a few hundred holes to to drill in 6061 and the bit would jam up when coming out of the material about 25% of the time. This was in a drill press with the work secured. Not a huge deal but slowed the job down. Read more
