knoweasyTitanium Step Drill Bit - 10 Step Sizes, High-Speed Steel 1/4 to 1-3/8 Inch - Perfect for Drilling Multiple Hole Sizes

Not sure about longevity to early too tell, seem to be durable and work great. Reminds me of Harbor Freight sets. Ideal for home use, industrial use only if you want to go cheap. Very nice kit and storage box.

Good value for money, comfortable

I needed to drill a 7/8 hole to run wire and conduit through a metal pole garage and these were just the thing I needed, made a clean perfect size hole.

I bought this bit set to drill panel holes for electrical conduit installation. I only required the 1/4 to 1 3/8 bit, but the price for 5 was 1/4 that of the single bit so I took a chance and am pleased to report I was not disappointed. The performance of the bit I used was on par with the professional bit I've been using for smaller holes. There was no deterioration in the cutting edge nor visible wear to the coating following initial use. The bits all have good heft and feel. The storage case is sturdy metal with snug cutouts for the bits and center punch. If you're looking for panel hole bits, look no further.

First time I used a step drill easy to use to drill large holes in sheet metal. Will keep it for other holes I need to drill.

These bits are tiny but they cut through metal duct work like butter. Just wish they offered larger diameter in this set. Comes with a carry pouch too.

I'm not an expert on these, and haven't had this one for long or used it extensively, but it did what I bought it to do. When using it "by the numbers" (ie, to make the exact size holes you want using the diameter markings on the bit without oversizing), you might want to stop & start measuring before you actually fully progress the bit to the indicated depth. The bit arrived on time in new condition.

This bit took a while to do one and it should be faster and cleaner. I've seen the expensive ones work and work well. If you need to do a few up to several this is your bit. More than that, I recommend a better option.

drill good

This worked really great on mild steel bar, Except the 1." For some reason, the one inch wouldn't cut, but all others did.Vendor replaced it and am now back in business.

Great product got what I ordered

Bought to put a 1" hole in a stainless steel sink, took forever, used cutting oil regularly, still ended up destroying the bit to get through the sink. All the videos said the easiest way was to use a titanium step drill for stainless steel, they were wrong
