Nice bits. Perfect for drilling into metal.

Nice, inexpensive set of bits
Nice, inexpensive set of drill bits. They're not very long, so make sure you know what you're getting. They're nice to have as replacements for others that I have broken so they fit my need perfectly. I'm not expecting to drill through diamonds with them...

Great for the price
I went through several bits from another set when trying to drill through a metal plate. These went through without breaking and without slipping. Pleased with this purchase.

Best bits ever made
Best set of bits I have ever owned. Drilled through titanium plated stainless with no effort

good for the price but didn't last
The bits only lasted for 2 holes. I used them to drill into a cast iron flange. It was ok for the price as two holes were enough to get job done. Still, If you are going to drill in cast iron regularly, I would look for better quality bits.

Sharp
I didn’t realize my old drill bits were so dull until I got these. Work well.

Great bits for stainless
I was smoking HSS bits, black tipped bits, and Titanium bits while drilling holes in 304 stainless. These bits go right through without work-hardening the stainless.

Good quality.
The drills are of good quality. Drilling ferrous metal and stainless steel went smoothly.

This drill bits did the job
Had a vinyl door with steel in the corners, the regular gold coloured bits would not touch it. Used a high speed corded drill and the cobalt drill bits got the job done easily. Definitely recommend.

Poor quality
Not useful for work with steel as advertised not sharp enough even not possible make existing hole wide just stuck and broke.

Was not happy with them
I was trying to drill out a piece of 1/8" steel for my BBQ rotisserie motor support they would start out OK then burn out very quickly, going red hot. Good for thin sheet metal but not for anything of thickness. OK for wood or other soft stuff.
