Greenlee 1904, 1904Pg, 1904PgSB, and 1906SB High Capacity Ratchet Knockout Driver sets are intended to punch holes with Greenlee punches and dies. The recirculating ball screw mechanism reduces by half the amount of force necessary when compared to conventional ratchet drivers.
These ratchet drivers can be used with Greenlee standard or Slug-Buster® punches and dies to punch round holes, from 1/2" actual size (12.7 mm) through 3" conduit size (89.8 mm), in plastic, fiberglass, aluminum, and mild steel. Greenlee Slug-Splitter® punches and dies, available from 0.598" actual size (15.2 mm) though 2" conduit size (61.5 mm), are capable of punching through all of these materials and stainless steel.
The maximum thickness of material that the punch can penetrate depends on the size and type of the punch. Refer to the Capacity Rating chart for individual punch capacities.
