Mittler Brothers High Throat Bead Roll Sets are CNC-machined from heat-treated steel for long life. Standard bead roll sets are designed for up to 19-gauge/.040" mild steel and for use with any high throat bead roller. Thicker metal (18-gauge/.050" and 16-gauge/.062") requires larger female roll to form a proper bead profile (i.e. 1/4" Male & 3/8" Female). All High Throat Roll Sets are 5-1/2" OD Upper and Lower.

Note: Bead size indicates width
