flintronicStep Drill Bit 5mm-35mm, with 1 Automatic Center Punch& 1 Twist Drill Bit, HSS Titanium Coated Double Slot Cone Cutting Drill

As described works well

All good

good quality

I got it today and used the centre punch and drill bit, which fitted in my smaller cordless drill...the step drill bit however did not fit my smaller cordless drill so I had to use my bigger cordless drill.. Be careful that you have a larger drill or else the step drill bit will not fit in .Apart from that it bored through my galvanised steel incinerator bin with no issuses, all three bits worked fine..not sure when i will use them again tho so cant vouch for durability over time

metal was very poor was blunt after just one basic cut, so because of this i can not recommend anyone purchasing this item.

I suppose you get what you pay for. Should have read the reviews first. Whilst this seems decent-ish quality, its obviously a cheap product from China and the diameter of the bit doesn't fit in a standard drill. I only wanted it to drill a hole in a water butt so couldn't justify the cost of branded step drill bits, hence buying this. The drill bit is useless unless I buy a heavier duty drill.Still, the centre punch will come in handy I suppose.

I used this tool to bore a total of ten 22mm holes in mild steel. I used a bench pillar drill on its slowest setting. Whilst drilling I used plenty of cutting oil to keep the tool cool.Due to the thickness of the steel, I drilled about halfway through then turned the metal over.The tool is still sharp and perfect for further work.

As expected
