Designed for punching holes in stainless steel, the Greenlee 7506 ram and hand pump kit combines bestselling Slug Splitter SC knockouts with the 11-ton power of the 767 hand pump and 746 ram, providing you with a powerful, compact knockout solution.
This kit comes with premium self-centering Slug Splitter SC knockouts. Designed to withstand punching through up to 10-gauge steel, as well as through a variety of other materials, Slug Splitter SC knockouts are long-life, abrasion-resistant, and even split the slug in two for easy removal from the die, saving you time when punching holes.
Self-centering Slug Splitters are designed to save you even more time when punching holes in stainless steel. The unique design saves time by automatically centering the punch to the pilot hole, removing the need to mark crosshairs. For use with U.S. standard-size conduit*, as well as a variety of other applications, the 7506 ram and hand pump kit is a small, powerful choice for any professional electrician who needs to get the job done faster, safer, and easier than ever before.
The Greenlee 7506 ram and hand pump kit comes with six Slug Splitter SC knockouts, six dies, three spacers, two drawstuds, a 3-foot-long high-pressure hose, and a sturdy, compact metal case for easy transport and storage.
The 316 stainless steel sheath (shaft casing) provides durability, strength, and maximum abrasion resistance. Rugged thermoset plastic miniconnector is compatible with all Oakton and Acorn ® thermocouple thermometers. Connectors and coiled cord are color-coded based on type: type J black, type K yellow, and type T blue.
The Greenlee hydraulic punch driver sets combine the 746 Hydraulic Ram with the 767 Hand Pump or the 1725 Foot Pump. These hydraulic driver sets are intended to be used with either standard or Slug-Buster punches and dies to punch holes through plastic, fiberglass, aluminum, and steel. Greenlee Slug-Splitter punches, dies, and draw studs are capable of punching through all of these materials and stainless steel.
Round punches are available for punching holes from 12.7 mm through 144 mm (1/2" through 5-5/8") in diameter, including 1/2" through 5" conduit and pipe sizes. Other shapes are available — square, special square, rectangular, “D”, double “D”, electronic connec- tor, oiltight with notches, and key.
The maximum thickness of material that the punch can penetrate depends on the size and shape of the punch. Refer to the instruction manual supplied with the punch for individual punch capacities.
Setup and Operation Instructions
- Remove the dust caps from the couplers; attach the hose to the ram and to the pump. Thread the dust caps together.
Note: Hand-tighten the couplers completely until all threads are engaged. Do not use tools.
- Select the punch, die, and draw stud that will make the appropriate size hole.
- Determine and mark the exact location for the hole. Using a drill bit that is slightly larger than the draw stud, drill a hole. This is the pilot hole.
- Thread the 3/4" piston shaft (B) completely into the ram (A). Refer to the illustration.
Note: For a punch and die with a 3/8" center hole, thread the 3/8" adapter draw stud (F) into the end of the piston shaft. For a punch and die with a 1-1/8" center hole, thread the screw sleeve (E) onto the piston shaft.
- Install spacers as necessary. Refer to the illustra- tions on this page.
- Slide the die over the draw stud with the open end of the die facing away from the ram.
- Insert the draw stud through the pilot hole.
- Thread the punch onto the draw stud with the cutting surfaces of the punch facing the material. Tighten the punch by hand until the spacers, die, material, and punch are snug.
Note: All of the punch threads must be engaged by the draw stud threads. If any of the punch threads are not engaged, dis-assemble the setup, remove one of the spacers, and reassemble the setup.
- Activate the pump. For specific instructions, refer to the operating manual supplied with the pump.
Note: Support the weight of the ram when operat- ing the pump. This will prevent the ram from falling when the punch is complete.
- Release the pressure at the pump.
