Review: Outstanding drill bits backed by exceptional customer service - These drill bits are genuinely very good quality and have performed extremely well for me when drilling into a wide range of materials, particularly metals (excluding concrete and masonry, as expected). They cut cleanly, feel well made, and have clearly been designed with durability in mind. During normal use, I unfortunately had two bits break. I contacted Stroton more to inform them than to complain, fully expecting at most a replacement for the damaged items. Instead, they responded quickly, asked no awkward questions, and simply requested confirmation of my address so they could send out replacements. To my surprise — and genuine appreciation — they sent out an entire new set, not just the broken pieces. This level of customer care is rare these days and speaks volumes about the company’s integrity and confidence in their products. Mistakes or failures can happen with any tool, but how a company responds is what really matters. Stroton handled this perfectly: polite, efficient, generous, and hassle-free. The replacement is already on its way, and I couldn’t be more impressed. Excellent drill bits, but even better customer service. I wouldn’t hesitate to buy from Stroton again and would happily recommend them to others.
Review: Sharp and fast bits - Had a box for over a year now. One use was on quite a few bits of steel from old power pylons, fairly sturdy stuff, hand held drill due to location. Another use has been on galvanized steel field gates, again hand held drill. Holes are made very quickly compared to other bits I've used, but I am an occasional driller rather than professional. They may be more brittle than standard HSS bits as we had a 6mm snap and a few larger bits chip at the ends. I think more careful use could have avoided this but that's hard to do with a hand held drill in some situations. I contacted the seller about the broken bits and within a few days I had a full replacement set! I am seriously impressed with their customer service and warranty.

### ⭐⭐⭐⭐ Decent Quality Bits At A Keen Price, Backed Up By Excellent Customer Service
*by M***N on 3 March 2021*

The item was sold at a keen price and delivered in double-quick time. I ordered the Cobalt drill bits because, having read the description, I believed they would be a more resilient bit than the normal HSS type, and would do the job of drilling out the sheared stub of a fixing bolt. However, I used two of the new bits to try and drill a pilot hole in the end of the stub and both of them very quickly blunted and lost their cutting edge, making no impression on the stub (I am unable to say what type of steel the sheared bolt stub was manufactured from). In view of this, and previously having blunted and broken several HSS bits, I was forced to abandon trying to remove the stub and used the Cobalt bits to drill a new hole through the 2mm steel sheeting which was easily achieved. And so, although the Cobalt bits didn't perform as I had hoped, they do appear to be quite a sturdy product and easily able to deal with cutting through reasonable thickness, normal steel, without a problem. As a result of the above, I contacted the seller to request replacement of the two damaged bits under the terms of their warranty. They not only responded immediately but did more than I anticipated, sending me a full new set of drill bits, as well as giving me a full refund on those initially purchased! What more could anyone ask for? If that's not excellent customer service, I don't know what is!! I recommend the company highly.
