I drilled 12 holes in 1/2 inch iron, in my huge drill, it worked 100 percent, it stopped the drill a couple times, but it did not break or get dull, very good product.

I do not recommend this product

Great product bit has held up awesome even after drilling out the steering knuckles on my jeep.

Great product for the money.

Product didn’t work as expected.

This product work just exactly as I expected it to

I used it once in a broken half he might be a good product I was making a small hole in to a larger hole that have something to do with

Very quick shipping, good product.

What to make a bad product and stamp "made in America" on it

Great product

Great product but not slot of attention to detail

Good Product
