Metric M42 8% Cobalt Twist Drill Bits Set for Stainless Steel and Hard Metal (1mm-10mm/19pcs) - desertcart.com

Review: Broke a bit and Stroton replaced with 5 no charge…!!! - I don't normally stop to review products unless it's something I use quite a bit and have tried other brands of the same type of product. Well I've burned, dulled, busted, even horribly abused all sorts of drill bits. They all seem to be about equal pretty much across the board. Some maybe a little bit better in performance. Nothing that really stood out to brag about. Ok I picked up this inexpensive set (I was going say cheap set because the price is very reasonable for what you actually get). These fricken drill bits are absolutely worth every single cent I spent on them. So worth it that I'm out here looking for a large set that has both metric and standard in the M42 8% cobalt grade these are. If you peck drill with this set I don't doubt they will last a good long time. And the warranty is incredible. Lifetime replacement. No one can beat that. I'll have to say tho, I haven't had to contact them yet for getting any replaced if needed. Let's just hope that would be a smooth process as well. I'm hoping. But I gotta tell you, I'm pretty busy at the moment, but stopped just to write this because I'm actually out here looking for a larger set from Stroton as where these came from. They are everything the boast in advertising and then some. Goes thru steel like it's no big deal. But remember to peck drill so you don't over heat the bit. That goes for any drill bit out there. But if and when you get these and try them, you will not be disappointed. At least I'm not. But then again I am 57 years young. So I have a little bit of experience on how to actually use a drill bit properly. If you don't have much knowledge about drilling, remember one thing, peck drill. If you don't know what that means, look it up. You will get way better results and your bits will last twice as long if not more. I know one thing, I'll get more than twice the expected life out of these due to the fact that they perform incredibly well. Like they stand out better than the average norm. They got me as a loyal customer. I really like'm. You'd have to tear them out of my dead hands to gett'm from me. So don't even try. Buy your own. They're right here, where you're reading this review. Good luck, have fun and happy drilling. Now a message to the seller of these bits.... where are the large sets of these bits. I don't see any. If you have one send me. Link. If not, than you'd better get one quick before I begin testing other sellers that have larger sets. Thanks for the bit. Good sht for real...!!!
Review: Really able to drill through tough metal. - They are really able to drill hard metal. I had a couple of screw who lost their head, I wanted to drill through to remove them. I was able even it was not easy, Nissan bolt are no joke. It is true the small bits broke easily, but Strton are great and replaced them right away. Very very satisfied.

## Questions & Answers

**Q: Can these drill through a car's trunk without any issues?**
A: These are made to drill through thick hard steel. Thus are very hard and brittle and will break easily if improper angle is applied. For drilling trunk or locks use a titanium bit and buy a few of them as they dull quick but get the job done.

**Q: Bought the 19 pc set; 3mm but broke immediately. Can anyone point me to where I can buy replacement? Thank you.**
A: Hi,I am the seller. You need to click  the blue word [STROTON] in  "Sold by STROTON and Fulfilled by Amazon" below the "Add to Cart" of this Drill bit's listing.
Then click [Ask a question] that write the condtion simply to Establish contact channels with me through Amazon message system.     Then I can handle the follow-up to your order.

Best regards
STROTON

**Q: Can they drill titanium**
A: Honestly,They are good for drilling steel and do the job well.
But Titanium alloy has very high hardness. And We can't guarantee.
If it doesn't work well, you could return it. If it works（Lubricant Must Be Used）, you could share it with other customers.

**Q: What is the length of these bits?**
A: They are average lengths.  The 1mm is 3.4cm and length increase proportionally to the 10mm which is 5.4cm.
