3Pcs HSS Step Bits, Ecbrt High Speed Steel Step Drill Bit Set, Cone Multiple Hole Cutter for Wood, Stainless Steel, Sheet Metal, Quick Change 4-12mm/4-20mm/4-32mm (Gold)

For the price I think they are well worth considering, mine do a good job with no problems.When you think other types can cost 3 times the amount and that's just for one.

I've never given much thought about how many drill bits we have, how we rarely use them all and how when you want to drill a hole you can never find the right size you want. These are good all-rounders, they have steps showing the size that the hole will be, they seem very robust (so far only used them on PVC and MDF) and the best thing of all they come in a miny pocket that takes up less room than multi drill bit.

these are truly excellent, bought them to perforate a steel barrel to use as a garden incinerator and they were epically good at cutting through steel, would definitely recommend the productComes in its own segmented cloth holdall/bag and offers a variety of hole sizes

The two smaller ones drill holes ok but the bigger one struggles with larger holes. Depending on what you are drilling if it's metal as that's what I am talking about. I'm certain larger one it would drill soft materials just fine. Hopefully this is of some help before you buy.

Omg absolutely fantastic, I needed to increase the size of bracket holes in order to fit masonry screws. I tried the day before ordering these to widen them with conventional drill bits, 2 hours later and I gave up. Saw these and had 12 holes done in less than half hour. It was like winning the lottery, one very happy lady 👍

Ok for what your paying. They will do the job on most materials.

Upon looking for drill bits to use with 5mm aluminium, I came upon this set. It is well built and the bits have been able to handle 5mm aluminium sheeting quite well, you just need to take it nice and slow. The set has 3 different bits in it, which is useful as it means I can drill more accurate holes where needed. Also is a little carry pouch which has helped to make sure I don't lose any bits as of yet.Hope this helps

Couldn't make holes bigger than 10mm. Larger sizes went blunt immediately! Cheap rubbish!
