The taps are priced OK but a new range and presumably that's why they're advertised here.
I looked at the rest of the rotating tooling and for example a 6mm 3 flute polished carbide end mill for aluminium isn't much less than a customer with an account might pay for Alu Power cutters from Cutwel Tools, I'm getting comparable performance and life to Alu Power from locally sourced cutters at slightly more than half the price and always on the shelf around 3 miles away :D

I'm a Gunsmith working in a wide range of Aluminium alloys, Titanium 6AL4V, 316, 304, 303, D2, EN1, EN1A and the list goes on
