Was struggling to drill stainless steel with standard HSS bits but these did it easily at the appropriate speed.
Excellent drill bits, went through the stainless steel like a hot knife through butter! Highly recommended!!
This set of drills is very good. All the right sizes and with use in variety of metals, proved reliable and kept their edge. A good price, too.
Great drill set- I wish I had bought them earlier.
Thank you Thank you Thank you Just what I wanted justbwhat I wanted
Yes drilled through plate steel effortlessly and still going on for more
Excellent. Tried on various mediums including allumium and brick.
Cheap (for Cobalt bits)...but they are not particularly tough. The cutting is fine, but the bits have a tendency to snap too easily.
Does the job well - sharp and easy to use, not sure how durable but they are cheap!.
Good quality at a fair price happy with purchase will do me for task intended fot
The bits did the job to drill 8 holes through 1.5mm SS, starting small, increased drill bit size but 6mm bit started to go blunt after expanding only 6 holes even with lubricant.
Good for the price but keeping to use again in future, they are not expected to last very long.
Was struggling to drill through 10mm steel with a variety of drill bits. These Cobalt bits made short work of it and i even stacked 2 x 10mm steel sheets together and the bits didn't blink with no loss of sharpness. I always use some oil as a lubricant to ensure bits last longer. Bonus is these are very affordable.
Worked well drilling the head of Allen key bolt ready for the bolt extractor
Really good drill does a good job on stainless steel.
Snapped and burns tips on 304 st/stl which surprised about even with cutting paste. Ceramic bit did the job in end as was desperate to get a job done.
Hadn't heard of cobalt drills and had struggled with my old drill bits. The cobalt bits made very easy work of the jobs I had. Would highly recommend.
I bought these to drill out rusty boots on my boat. Three of the set broke after four screws. Waste of money.
Good quality. Great performance. Easy to use in case of very hard steels.
