SS SHOVAN 3PCS HSS & M35 Cobalt Spiral Step Drill Bit Set (1/4"-7/8")

Quality outstanding. I am going to buy more because of it usefulness. It fits in DeWalt drawer. Compatibility is very good between impact driver and drill. But works better on the drill

So far so good, not really done anything serious yet but they've done sheet metal like it was cardboard so I'm optimistic!

Not the best but ok for hard surfaces to drill 👍👍👍

Spot On cut through steel pipes easy

I ordered this set to see if I could drill holes into a thick piece of steal tube that I have used to burn chopped up pallet wood in. WOW ! I am very impressed by these ones I’ve so far only used the largest step drill bit & it still looks brand new (see photo)👌. I also ordered WD40 Specialist Cutting Oil for the task. My method was to gently squeeze the trigger half way on my Bosch drill let go & repeat. I kept the Step Drill bit lubricated the whole time. Each hole 13 in total took about 25 minutes to do, again I didn’t want to go full speed & end up damaging the drill bit. The Step Drill bits also come in there own protective case so I can safely store them away for another day.

Well presented, protective fitted case.Seemto be reasonable quality. I haven't used them on more than thin plate at the moment. But the do seem to hold up well to general diy use.

cut v well , quality at a great price, and top service rhx

Good product

These are exceeding expectations. I am using to drill 7/8 holes for grommets in a new red iron building. This are 1/4 steel beams and they just get through it with ease. Maybe starting to slow down a little but have done 20 to 30 holes so far. I use a self drilling screw to start the hole which necessary and then follow with this.

I bought these for my husband since he works in HVAC, he said they worked amazing. The bit set is perfect for drilling.

I was a little hesitant to try these bits on a recent vehicle project. They worked great! They are very sharp and even after drilling out two grade 8 bolts, they are still very sharp. Value for money: I didn’t want to spend too much money and these seemed like a great price. They outperform my expectations.

These turned out to be good quality bits. I've been using them to drill out holes in metal, custom guitar amp chassis and they've held up well so far. Nice case too.

Good quality and worked just fine. Didn't push the bits. Let them cut and penetrate at their own pace. Didn't need oil or water to cool bits either. Used to bore holes in a old water bladder tank to drain. Worked great. Don't know about thicker metals since I didn't need them for that purpose.
