beetle holes

I agree that these holes were made by beetles, but I'm not sure which type of beetles. As far as I can tell Dryocoetes betulae is not a British species; there are related species of bark beetle found in Britain, but I thought most of them made smaller 'gallery' type burrows immediately under the bark, rather than these more substantial holes going into the main truck. Possible they were made by one of the longhorn beetles? Do you know what diameter the holes were, that might narrow things down a bit.

Beetle holes

The holes were about 2-3mm i think.
I'm still not sure on the identification myself i was looking everywhere to find out what type of beetle made this hole and that was the nearest i got.
