Love bombing - coined in 1970s and used by actual psychologists.

Closest would probably be toxic positivity.

Believe it or not these were made using a brad point bit. Others have mentioned the low budget quality + it becoming dull and I imagine that's a big cause. Thanks for the fisch recommendation, I have been looking and don't really know good brands for bits, so that's really helpful!

I hadn't considered the quality of the bits, but that's a fair point. These are from sets that are probably $25 max, I'll be sure to grab some higher quality ones, I didn't realise that would have such an impact on something like drilling holes. Thank you.

I failed to clarify properly, but these are actually not through holes too. The router sounds like a good idea - these blocks are about 10cm x 10cm though, would you still be able to do it with your jig without the router tipping?

Woops! I've fixed the title now. I'll give this a try, thank you.

I'm sorry I didn't clarify this in the original post - the holes do not go all the way through as they are for putting metal crochet rods in.

I think countersinking might cause issues. This is for a crochet board that a friend requested. The pins that sit inside might wobble a bit too much. I didn't realise faster speed would be better, I imagined it would be rougher, thanks for that!
