Metric 25Pcs M35 Cobalt Drill Bit Set, 1.0mm-13.0mm HSS Cobalt Jobber Drill Bits for Hardened Metals, Stainless Steel, Cast Iron and Wooden Plastics, with Metal Index Storage Box

This drill set was just what I needed for post-processing of 3D prints. I do all my prints in metric units so I needed a metric drill set. The plastic case was fine and it was flat enough to fit in my shallow tool chest drawers.

Very good quality bits. 10mm is hard to find needed it for a machinng purpose

Works great

Decent quality, good price

Former CNC machinist, these are good quality cobalt drills.

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.

Heavier than ususal. Cut well

Sturdiness is good

Good drill bits. Case is cheap plastic & bits are not held securely in position. Bits prone to rattle round in case.

Price is ok

perfect

They work fine. Bought this to have a metric set. I will replace bits with higher quality ones as they wear out. Its exactly what I wanted.
