I wanted some sets of metric taps and dies to cut threads. The website was unclear if the dies were HSS (or carbon steel) and if they were split or not. I queried both points and was assured by email that the dies were HSS and split - I then placed an order on this basis. On delivery, the taps were all good, but the dies, whilst HSS, were not split. This means the tolerance of the thread being cut cannot be altered, which is a significant problem. I queried this as a possible manufacturing mistake, but I was then assured, contrary to my first enquiry, that all dies supplied by UK Drills were not split. I was offered, and accepted, a full refund for the dies. I also found later that the outside diameter of these dies was a mm or so less than my die stock holder, which fits all of my split dies made by Presto etc, perfectly. In conclusion, the website description needs to be much clearer about ALL of these important details and, when queries are made, the answers should be helpful and accurate, rather than false and misleading. Otherwise, the goods appear to be decent quality and value.
