Impact Drill Bit Set, 1/16"-1/4", 16pcs | 13Pcs Set+3 Pcs Free, Premium 4341 HSS Titanium Impact Hex Drill Bits for Wood, Steel, Metal, Plastic, Quick Change Design

Pretty good bits. I drill 1/4” steel flat bar to mount signs. I can get 14-16 holes before the bits stop cutting well. My company buys a different brand but I keep a couple boxes of these in my toolbag as backup. They are less expensive than the company bits but work just as well.

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.

Very Good Basic Set Of Drill Bits With Hex Shanks and as described by seller although be prepared to stop the bits elsewhere... the case is very lacking...

Great multi pack you can’t get at Lowe’s or Home Depot. These are always useful as pilot bits , nice and sharp , reasonably priced.

Decent set. They seem to cut ok. We'll see how they last.

Very good selection of small drills. They fit and work well in my portable hand drills. Highly recommended.

Problem with one drill bit (7/64) breaking. I tried to contact the vendor and they didn’t respond to me. Hope the rest aren’t as brittle.

Sturdier than my older worn out drill bits.

Excelentes la verdad muy buenos materiales duraderos

Appear to be a good quality. They are true as fas a straight, no wobble.

Good drill bits. Easy to drill hole on metal.

Penetra el metal como si fuera madera y con una sola broca he realizado mas de 50 perforaciones en perfiles de 3 mm de espesor además su mango hexagonal evita que la broca deslice en el mandril del taladro. Increible producto.

Muy buenos
