I got the 7mm one on Thursday and my first reaction was that I had misread the listing and it was only the 7mm one from a set. so I fired off a refund request and got the reply that they would refund £2 and I could keep the reamer. The rest of the set arrived on Saturday, so I cancelled the complaint and sent them a message that they were running their business in a twattish way (not my exact wording).
Either they are sending out from two different locations, or they have an idiot in charge.

Who cares ! The reamers are OK for the price.

Here's a question about reamers - I acquired a NIKKEN NCS tool bit that looks like a rotary broach, or a long shanked, downcut, slot cutter with a funny end, but it is marked 7.873 +/- 0.0126. I presume that this is calculated to make an 8mm hole. Am I right in this assumption ?
