Carbide square end mill, 4 flute, in 18 stocked sizes from 1mm to 12mm cutting diameter, held within ±0.003mm. Square end and flat end mill are the same tool — square is what the catalog says, flat is what the floor says. Shanks are 4, 6, 8, 10 and 12mm; overall lengths 50, 60, 75 and 100mm, and the 4, 6, 8, 10 and 12mm diameters each come in two or three overall lengths, so a deep cavity does not force you into a longer holder. Solid tungsten carbide with a nano coating, so it keeps an edge in hardened steel up to 62 HRC. Metric sizes are stock; imperial on request.
