## Features

- 40PC FRACTIONAL INCH BITS - The set includes 40pcs of M35 cobalt steel twist drill bits, 3/64" x 10pcs, 1/16" x 10pcs, 5/64" x 10pcs, and 3/32" x 10pcs. Manufactured to German DIN338 standard. Packed in a plastic bag.
- FOR METALWORKING - Particularly successful in cutting through hard metals(hardness less than HRC38°) such as stainless steel and cast iron, although they can be used for softer materials like copper and aluminium, too. Not for hardened steel / high carbon steel. Try to adjust the RPM when it fails to penetrate.
- DOWNLOADABLE USER GUIDE - We've summed up some tips of drilling metals, including a RPM chart for several common metals, based on our reviews and some articles on the internet. In most cases, our customers would get a much better result with these tips. Welcome to download.

## Questions & Answers

**Q: Are most of these reviews fake? 50 real cobalt bits for $15 is impossible.**
A: We swear every review in our store is real. Our living relies on this account. We'll never risk making fake reviews, or it might be closed by Amazon.
Pay attention to the size. These bits are small. The 1mm is like a needle.
You guys paid extra too much for those famous brands before.  Selling it at $15 is profitable for us.

**Q: is the drill bits pure cobalt?**
A: Thanks for your question.
Cobalt drill bits are not made of pure cobalt, but rather a steel alloy with 5 to 8 percent cobalt. The 5-percent alloy is known as M35 grade, and the 8-percent alloy is M42. 
These bits are made of M35 grade cobalt steel, with 5% cobalt added.

**Q: I want to drill 9 to 12 holes through large, stainless steel hinges (3mm thick).Could I do the job with these drills?**
A: Quality of hinge is the variable here. I would buy a single cheap coated drill bit first. If you can drill one hole with the cheap bit, then you should be able to drill 9-12 in the same material with this set. As always use cutting oil and make sure your press is set to proper speed.

**Q: What size is the shank on these?**
A: Size of the shank is the same as the size of the drill.
