The largest in the Criterion line, this head was designed for extra heavy duty. The wide
bar holder base, common to our entire line, permits maximum stock removal while
maintaining rigid control of accuracy.
Holes up to 16" in diameter can easily be bored with the use of a sturdy 1-1/2" bar in the cross-hole.
A 2-1/4-10 threaded back permits its use with the shanks shown on the bottom of the Shanks and Adapters section.
