I'm fairly new to carbide tooling but just about everything I've had from APT has been good gear. In a rush to order my replacement 10mm carbide end mill, which had a race against the clamps and lost, I ordered a 2 flute by mistake. These end mills are good quality, sharp and as tough as old boots but the overriding positive is the service from APT. Very efficient. Even during lockdown. Thankyou. And no Im not sponsored.
