What Customers Are Saying
The cobalt drill bits demonstrate mixed performance. Many users report the bits effectively drill through hardened steel, stainless steel, and other tough materials, with some describing them as highly capable. However, a significant number have experienced issues, including bits breaking, dulling, or failing to meet expectations, especially with smaller sizes. While the bits appear well-suited for challenging drilling tasks, the quality and durability seem inconsistent. Users recommend caution, slow speeds, and cutting oil when drilling, especially with smaller bit sizes.

Would Not RecommendI purchased this set a few months back and have experienced mixed results. Some of the bits in the set work excellent and others do NOT. The 5/16" Bit completely wore out after roughly 10 holes. Is this something other customers have experienced? How do I get this bit replaced free-of-charge?

Nice Bits
Would RecommendBits stay sharp for quite a while. I’ve used them on multiple materials and they work well on everything.

Worked well, exactly as expected
Would RecommendIt worked exactly as expected and fit into the DeWalt battery operated drill we have.

Not worth buying then having to return.
Would Not RecommendAwful drill bits. Kept on drifting as opposed to cutting. I smartened up and bought the Cle-Line. The poor man always pays twice. If you think that metal bits are supposed to take a long time to cut, you got the wrong bit son.

Cobalt Bits
Would RecommendUsed all sizes in steel angle iron to drill pilot holes and 3/8 holes. All bits cut right thru the metal and worked really well and made the job a breeze.

Good bits, struggle with hardened metals.
Would RecommendHeld up ok, but shattered a bit the next (the one i needed of course) so I returned them. Did manage to make some progress on a snapped off hardened steel bolt but didn't hold up quite as advertised. Still a solid set though.

Okay
Would RecommendI tried to use this to drill through stainless steel pipe. One of the bits broke right away. I tried again with the other size of bit and it went through

Lasted one job
Would Not RecommendUsed it to drill out some sheered exhaust bolt, followed typical steps, lasted two bolts…not worth the amount paid.
