3PCS HSS Step Bits, High Speed Steel Step Drill Bits Set - (4-12mm, 4-20mm and 4-32 mm) Cone Drill Bits Hole Cutter for Wood, Stainless Steel, Sheet Metal by SS SHOVAN

Absolutely brilliant. I’m sure there are better on the market for much more money however for this price you can’t go wrong. I used them for 2mm steel, like butter.

They work very good

good

I very rarely leave reviews for anything, however, this is such a great piece of kit that I felt I just had to. They work exactly as described. I use mine with a DeWalt impact driver and managed very easily to expand the holes in a hinge without any issues at all. They did a very neat job and I can see no visible wear at all. Five stars every day of the week.

Arrived timeously, and does exactly what it was designed for. I needed to make nylon washer holes a little bigger for a project, and it did a fantastic job.

Great bits for what they are. Sharpened ok

the product cuts very well - as long as the surface is oiled as per instruction, BUT the shaft is of inferior quality and mine sheared off while drilling the 3rd hole in a galvanised pipe. i was quite disappointed as it cuts so well.it was still worth my while buying it as it got 90% of what i needed done and i was able to finish the final hole using a sanding stone on my drill.

These were perfect for what i need.
