Fair to good quality for the price

Bought to drill about 450 holes in .25 steel. Requires moderate pressure to drill, doesn't seem to run, and will hold 100 to 200 holes per bit before dulling. would recommend.

Pros
  • Jobber drill bit
Cons
  • New competitors emerged

Best value for money

Best value for money. These little bits are amazing, I use them to drill pilot holes in 1/4 gauge mild steel with a cordless drill and they just keep going. I easily do 30 holes before they slow down and I don't use lube. As long as you keep the drill straight and move slowly and let the drill cut you will be impressed.

Pros
  • Twist drill
Cons
  • unreliable

Waste of money on power tool parts and accessories

These drill bits are crap for a keyless chuck. First, the thighs are smooth. There are no edges for a drill chuck except at them. So unless you have a drill press or an old chick with a wrench, they're going to slip. Second, they are not very sharp. They cut great for the first minute and once you surface and start a hole it slows down from there. I drilled 3/8 steel and it took 10-15 minutes to drill through. Don't waste money on them. They technically work, but not very well, so I cannot…

Pros
  • power tools and hand tools
Cons
