Reviews
Cobalt Drill Bit 4mm (2 Pack) is rated 4.3 out of 5 by 138.
Rated 1 out of 5 by from Not recommended Not 12mm, it’s actually 10mm, waste of money and not fit for purpose. Can’t even return as they are not accepting returns due to covid-19

Rated 5 out of 5 by from Great cobalt bits Love these bits, I’ve bought some other sizes previously and they have been life savers. They can drill through just about anything you throw at them!

Rated 5 out of 5 by from Great Drill Bit Used for drilling SS. I used 4 HSS to drill one hole where one of these drilled 10 holes and is still going!

Rated 5 out of 5 by from Great drill bit A 3mm drill bit was needed for a split pin hole through a 1 1/4" 316 stainless steel propeller shaft. Expecting a difficult job I bought more than one pack. Only needed 1 drill bit! Excellent! Keep the revs low and use plenty of coolant - job's a goodun!

Rated 5 out of 5 by from Pilot Drill I bought this pack of two drill for pilot holes, I didn't think they would last but only used 1 drill and still as sharp as when I bought them. More then happy with this purchase.
