Metric M42 8% Cobalt Drill Bits Independent Packaging of Each Specification for Stainless Steel and Hard Metal (3.5mm x 5pcs)

I did eventually snap all five drill bits but managed almost a hundred holes through hard steel before they all went. Far better drill bits than any I got from Screwfix or B&Q. Only other metal cutting bit I have found that are comparable is the dewalt extreme 2 but tbh these are better and cut holes faster. Highly recommended

I do industrial electrical work these go through trunking and conduit back boxes very fast, best bits ive bought ☆☆☆☆☆

Used to drill through a 6mm thick stainless 304 bar. More effective, faster than my other drill bits.

Quite disappointed, it did not go through wheel nut, but a drill bit from my dremal did. So will not recommend to anyone.

Bought this pack of three on the back of two larger 11mm STROTON drills which did work well. These three one okay (soon blunt)one iffy, third didn't use - had no serrations at all

I read the previous reviews and was unsure as one reviewer said they wouldn’t drill through thin steel. I drilled 12 holes through 5mm stainless steel using a pillar drill and I was immensely impressed by how quickly they went through. Didn’t have any machine oil so used WD40 spray to lubricate/cool the drill tip. Would buy again and recommend them.

Good Quality product

Exceeded expectations can definitely recommend for stainless steel

This company makes bits as good as any top brand...even better than most I'd say....you will not be disappointed with them

Super produit. J'ai percé de l'inox 6 mm et de l'acier très dur 6 mm sans problème. C'était pour tester, j'ai commandé la boite complète. Je recommande ce produit.

Alles ok

Probadas y funcionan muy bien.Comparadas con unas que tengo de M35, les da mil vueltas.Compra recomendada

Ottimo prodotto, meglio usare con una goccia di l'ubrificante.
