Great quality
Best drill bits money can buy. Iâve researched lots of brands and these are truly the best. Goes through 3/8â metal with a pilot hole and lubricant with ease. Theyâre very sharp and clean cutting and make quick work of metal projects

Great kit
I believe the value for money in this kit is clear as there isn’t the need to purchase multiple drill bits to work with. I can’t say how durable it is but considering that I’ve used one bit to drill over 40 holes in different metal thickness, I believe it should be able to get to 100 and still be drilling holes in metal smoothly.

Totally worth it
I finally broke down and spent a little more on a set of step drills, glad I did.These cut until the cows come home.I drilled about a hundred holes in a barrel building a smokeless fire pit and it was crazy fast and the drill bit is still like new.Very happy with the quality and performance and will be buying a set for my dad as well.

Nice holes
A sharp step drill is the hardest thing to find. These are nice step drills that are very sharp and make nice round holes. Kinda expensive but if you want something that will last, pay the extra money. I’ve had these for about 6 months.

Best bits I’ve ever used
Drilled 22 1/2″ holes in my Teske trailer. Still like brand new. Starts like a quality bit then zips right thru to the hole size. Went so fast with the hole I went past the 1/2″ mark.

Best step bits
These hold up much better than Milwaukee or other bits. I primarily use them on 1/8″ mild steel. I know they aren’t rated for that thick but they work great. Drilled some 5/8″ holes in 1/4″ steel and there’s no detectable wear or damage after 12 holes.

These are one of the best bits that i had in my life. Easily going through 20GA and up of sheet metal. Bits are sharp and durable.

This drill works perfectly leaving a perfect hole with no Burrs. It is fast in soft and hard materials. Well worth the price.
