Title: Sharp and fast bits
Review: 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.

Title: Great drill bits, even better customer service
Review: These drill bits really are excellent. They grip really well and actually pull the bit through when drilling wood. They stay nice and sharp and the warranty is perfect.Note to all suppliers – this is how customer service should be.I had an issue with one not. Contacted them following the instructions provided and received a response and confirmation shortly afterwards. Then received a replacement bit a couple of days later – excellent service.

Title: Drill bits.
Review: Useless Chinese junk.They are not known to be producers of high quality steel and it shows.Went straight back after drilling one 6mm hole in mild steel with a pilot hole and it chipped so easily.I shall be sticking with ‘Dormer’

Review: Bought the drill bits to drill holes in stainless steel trays. Works really well but did end up stripping one drill bit. Messaged the company and they replaced the drill bit with no issues. Came quick too. Great drill set and awesome customer service.

Review: First off I NEVER leave reviews on products. This company is better than Snap-on and all the tool trucks on their warranty policy and I’ll tell you why.First of all, the bits are great! They have a great cutting action and cut through hardened steel like butter. They really are quality bits. However, they ARE 8% cobalt which makes them very brittle. Any bit that’s 8% cobalt is going to snap now and again especially when using the smaller sizes on hardened steel.The reason I say they are better than tool truck quality is that for one, they cut hardened steel like butter just like any Snap-on or Matco 8% cobalt bit will. The second reason is their warranty on the bits and their prompt customer service responses.I’m a professional mechanic and we tend to drill out a lot of broken off license plate bolts so we use the 3mm, 3.5mm, 4mm, 4.5mm and 5mm drill bits to gradually drill pilot holes into the broken off bolts and then re-tap the hole with the standard 6×1.0 tap that most cars have their license plate bolts threaded to. I first broke a 3mm, contacted the company, and they sent me a 5 piece kit of their 3mm bits for nothing! Now I recently broke a 5mm bit yesterday, I contacted Stroton again and they got back to me within 24 hours. I mentioned that I broke the 5mm bit now and explained to them that I love the cutting action of these bits and also mentioned that I use the 3mm to 5mm bits often for broken bolt removal. Instead of just sending me one 5mm bit to replace the bit I actually broke, they’re literally sending me a 5 pack of each size from 3mm to 5mm (including the half sizes) so if I break another bit I’ll have extras on hand!The tool trucks typically have a warranty on their bits, but they put a disclaimer in there that says they won’t replace ANY bit for free if it’s from a certain size down because they know they’ll crack easy at 8% cobalt and they don’t want to replace those smaller sized bits because they know people WILL break them. This company literally just sent me a boat load of bits to cover me just so in case I break another small one, I’ll have 4 more ready to go now in the event I snap another one! Their warranty policy is basically, “you break it, we’ll replace it”! GREATEST COMPANY AND BEST WARRANTY POLICY PERIOD!
