Metric threads of: 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.25 and 1.5 mm pitch were available and 16, 18, 20, 22, 24, 26, 28, 30, 32, 36, 40, 48, 50 and 56 t.p.i. For screwcutting very much slower speeds than those normally provided were necessary and Emco offered both a mechanical slow-speed kit (a motor-mount bracket that carried an extra pulley) and electronic speed control of the motor.
