It really works!
I occasionally could have used one of these over the years as a contractor, but just got by using increasing sizes of drill bits. I selected this one over similar available step bits because it said it could cut through stainless steel, quite a difficult task. I used it yesterday to drill an extra faucet hole through a new stainless steel sink. It cut through fast as if it were cutting plastic. This is a good item, not foreign junk that only looks decent before you use it.

Works as advertised on stainless Steel turkey fryer
This is about as simple as it gets for a step drill. I used it it drill a 3/4” hole in a stainless steel turkey fryer. I purchased a DERNORD Stainless Steel Ball Valve - 1/2 Inch from amazon for the project. Once the 3/4” hole was drilled I used a rat tail file to open it up to approximately 13/16”. Applying light pressure after drilling a 1/4” pilot hole; step drill worked as advertised.

Don't bother
The large size would barely drill thin plastic. Garbage!Very poor quality.

Great tool to have
This product is very handy when sizing the right hole however the sharpness to drill metal holes could be better

They work - barely
I knew I needed an 18 MM hole so I predrilled every hole to withing 2mm of the final size.These did the job, but it took excessive force just to cut the final 2mm.I didn't find any others in metric so I can't recommend anything else.

Love these!
These fit into my 1/4 speed chuck and just make life convenient. I work in HVAC and my normal drill is usually out in my truck or in another bag, but I always have my impact driver. I can just pop one of these into my impact and quickly drill a hole with these uni-bits. Super inexpensive and they seem to last as long as the super expensive ones at the big box stores.

Worked like a charm, good value for price
Bought this to drill in the stainless steel sink, worked like a charm. Good value for money compared to what is available in stores. Not sure about durability since I only needed this for a one time use
