When you look at the packaging you know what you have received is going to be good and it is with very little TIR run out, thanks APT will use you again. Ken Haddington.
Excellent quality. Quick delivery. The spanner flats are a real plus as I had been shearing the pin in the captive nut on the draw bar. My milling machine had no other way of clamping the spindle. The spanner flats allow me to tighten the cutter correctly in the collet holder. 36mm A/F is an odd size. Maybe stock some low cost wrenches and sell them as well.
