Review: good quality - Very impressive on its functionality. I purchased before Milwaukee and Dwall drills and they did not performed correctly, as a matter of fact, they got broke and it took kind of long to perform the drilling. With this MACKCPIP cobal drill bit set, i drilled like 5 holes with out any issue. Except for the smaller drill bit got broke, but the other one i used worked more then great!!!
Review: Strong cobalt drill bits cut hard metal well - This cobalt drill bit set performs really well on harder materials. The bits stay sharp and cut cleanly when used with proper speed and pressure. Sizes are accurate and the set covers most common needs. Used them for metal drilling and they handled the job without overheating or dulling quickly. Great value set for DIY or shop use and a nice upgrade from standard bits.

### ⭐⭐⭐⭐ Another one of those sets you don’t use often but…
*by J***E on April 30, 2026*

I use the MACXCOIP cobalt left hand drills to remove broken bolts, studs, and fasteners. They’re very hard so they are subject to breaking. Don’t use them too agressively or with a very high speed on metal. They seem to be good quality and very sharp. These are special purpose application only and should last.me for many years. The set came in a plastic index case to keep the jobber-length bits together and easy storage. Good value.
