Very good drill bits
Great drill bits. They cut through stainless steel very nicely if you take your time and use a cutting fluid to keep them cool.Had a minor issue with one of the bits snapping (my fault) but the seller took care of the issue immediately and was very responsive.

They do drill stainless steel!
At first I was a bit discouraged as per instructions I was using low speed drilling. It was not going through stainless steel at all. Then I switched to high speed and this was when the drill started to made it through with ease! Just to mention here that bits (Titanium coated) from Canadian Tire were absolutely useless!!!!No sign of overheating, bits stayed sharp through at least 10 holes for my first project using these new drill bits.I hope it will continue for years to come.Added on November 28, 2025. This set is amazing! Drills through SS almost as through wood. I use drill press with medium speed. No overheating or strange noises. Just goes through at steady speed.Highly recommended!
