    I'm very satisfied. Compared to cheap tap drill bits from local store (still more expensive than this set from Banggod) these bits are excellent. I tried one of them on a piece of iron (see attached pictures) where bits from local store weren't of any help and the result is perfect. I'm just a DYI hobist, not professional, so I can rate only based on my limited experience, but I think at least for occasional use these bits will be more than suitable. Just to be clear I used the bit in electric drill to drill a hole only, then removed the bit, put into handle and did the taping slowly by hand. It went without applying force, the bit was sharp and even I proceeded carefully turning the bit backward few times, it wasn't necessary and it would work also in one go.

    Excellent value for the low price! These work great if you just respect the following: Don't run at high revs - use a hi-torque cordless with a brake. Repect the short length drill part - don't try to thread anything thicker than the drill's free length. These drill diameters are somewhat small, achieving a really deep thread depth, that'll be tough on the tap, your drill and your wrists (if handheld). I'll personally only use them on cast iron, cast aluminium and mild steel. I'd never ever let the smaller ones bottom out into the purported "deburr/ countersink" feature - jeez - Marketing BS. For heavier alloys I'd still use predrilling to lesser thread percentage and continue using my old straight-fluted taps.
