Very strong
Only used one to drill out 8 hardened steel screws. Went through them easily. Very sharp and at a great price, will just be another addition to my garage tools

At Last
I am always using drill bits in my line of work, I have always used HHS bits and they for ever snap and drill one hole and then need binning. I tried these Cobalt bits and was amazed at the difference, they are 100% better. I am currently disposing of all my old bits and replacing with Cobalt.

Great for drilling through steel lintel
My other drill bits were just not working on the lintel above my doors for a roller blind installation. Purchased these and they were like a knife through butter. Only needed the one bit to make 8 holes!

Hopeless Drills !
Blunt with mild steel a one-off use then throw away, very poor quality.

Small drill bits, & that's not the diameter
Surprised & disappointed to see how short these drills are. Didn't come in plastic case. Manage to drill one hole in 4mm steel, very poor performance. I started a return but decided to soldier on. Neither would I Recommend nor buy again
