A plurality of rolling elements such as cylindrical rollers or spherical balls are retained in pockets formed at the die entry area.

The rollers in the die entry area and on the punch may be arranged in rows that form a tangent surface that engages the sheet metal blank as it is drawn into the die cavity.
