ill hold my hands up and say i thought it would be a lot more to buy, normally new ideas like this command high prices, i was expecting a couple of hundred for the head and a tap tbh.They have their prices on their website like this

I suppose it depends how many holes you are tapping to make it worthwhile going for something like this.
If you are tapping 200 holes and it costs £50 then its £0.25 per hole.
If you are tapping 10 holes and its £50 it'll cost you £5 per hole.
seems like £100 would get you going on 16mm drill and tap + head.
not bad if you were doing a lot of holes the same size altho having a range would get more expensive.
its a good idea for repetitive jobs.
i see they do an arbor for a mag drill, i thought that the action of the impact wrench was the key to it but it seems not.
they basically have re invented the wheel somewhat, just made an adapter system that ties you into the brand.
good marketing if they can shift them.
