Metric 13Pcs M35 Cobalt Drill Bit Set, 1.5mm-6.5mm HSS Cobalt Jobber Drill Bits, for Hardened Metals, Stainless Steel, Cast Iron and Wooden Plastics, with Plastic Index Storage Box

The size graduation is perfect for certain work I was doing. The price was good. These are decent quality, not crappy. These were sharpened properly and wear well.

Nice bits, nice case. The plastic pull feels like it could break someday but if it does it would be easy to replace with a metal one. I like how the bit holders stand up and stay there

Value for money product, bits could be better for sharpeness, material is average not recommended for tempered steel.

I got the Metric 19Pcs M35 Cobalt Drill Bit Set and it’s excellent. I’ll be looking out for more products from MACXCOIP. The drill bits come in a nice, albeit slightly on the thin side, case. Overall, a great buy!

Used to drill into a pair of hardened steel pliers. Worked like a charm.

I had to use the mini chuck, Amazon item B096VC6V9 to use these in a drill press. They are sharp and when used in a hand drill, (again needing the mini chuck to be able to pull bit out of wood when making a deep hole) the bit will bend a little bit and wobble and you can bend it back. This is super forgiving compared to the carbide bits where the material moving the slightest amount would break the bit, even when using a drill press.If you plan on using these, I strongly recommend a drill press, and don't press faster than it cuts, which is pretty fast. They do flex and are slightly forgiving but more than a couple degrees off angle and they will break. So the number included is a deal maker for me and I'll be getting more of these when I run out.

This was only one of the few good quality drill bits I found that used the metric system. It was perfect for drilling in the holes for my mirror. This had up to 13mm which was perfect since we needed 12mm. This is one of the few products on Amazon that had a bigger size.

I get a lot of grief from friends when I buy cheap tools they tell me tools are an investment they tell me that tools reflect my Level of professionalism they tell me that tools in fact determine how well I can do a job.I get cheap tools because I forget where I put them and leave the job site without having them all my person or somebody mysteriously borrows them while I'm at lunch or the bar.That's where something like these come in handy they are inexpensive great for just doing a single task definitely go through most metals with no problems and they come in a pink case that you just cannot wait to throw away.I would get these again and they're worth you giving them a try.
