Greenlee Battery-Hydraulic Stud Punch Kit – 120V Charger

Description

Punch clean conduit clearance holes through heavy steel studs by operating the Greenlee ESP710L11 Hydraulic Stud Punch across commercial framing sites. This cordless hydraulic punch pierces twelve-gauge structural steel studs in five seconds. It requires flat stud flange clearance, preventing punch engagement inside narrow stud corners or track channels under two inches wide.

High-strength forged alloy steel constructs the open C-frame punch jaw and hydraulic cylinder collar, mounted to a glass-reinforced composite inline tool body. An 18V electric motor drives an internal micro-hydraulic pump, producing 6.5 tons of punching downforce at 8,500 PSI. Total tool weight measures 11.8 lbs with battery installed. Machine dimensions measure 17.5 inches long, 4.5 inches wide, and 9.5 inches tall with battery dock.

Key Features of Greenlee ESP710L

Electricians buy Greenlee ESP710L stud punch kits to route pipe through steel framing without hand pump strain. Equipment pricing delivers 6.5 tons of hydraulic force, an 18V battery, and a 120V charger in a contractor kit.

• High-pressure micro-hydraulic pumps develop 6.5 tons of punch force to pierce twelve-gauge structural steel studs.
• Open C-frame jaw designs slip over standard steel studs up to 2-1/2 inches wide without binding.
• Hardened tool steel punch and die sets produce 1-11/32-inch holes to fit one-inch conduit bushings.
• Auto-retract hydraulic valves return punch dies automatically once steel penetration is achieved.
• Full 360-degree rotating heads allow horizontal and vertical punch orientation inside tight stud bays.
• High-capacity 18V lithium-ion battery packs deliver over two hundred punch cycles per charge on framing sites.
• Integrated LED work lights illuminate dark wall cavities and framing tracks during hole punch setups.

Hydraulic Stud Punch Bench Metrics

Calibrated load cell bench testing confirms 6.5 tons of punch force delivered at 8,500 PSI peak hydraulic pressure. Complete punch cycles take 4.8 seconds through twelve-gauge structural cold-formed C-channel steel. The 18V motor draws 16.8 running amps from the lithium battery pack during peak metal rupture. Hydraulic auto-retract valves open within 0.05 seconds of slug breakthrough, resetting the punch rod for the next hole. Sheared hole edges show zero burrs or metal tearing, seating snap-in plastic bushings flush without hand filing.

Framing Bay Usability Realities Maintenance

Positioning this 11.8 lb tool over stud centerlines takes two hands for accurate hole leveling across vertical framing. The trigger gives instant ram advance with automatic retraction upon punch breakthrough. Do not buy this punch tool for structural steel I-beams, plate armor, or blind conduit holes in junction boxes.

• Wipe metal shavings and oil residue off the punch dies and C-frame jaw after each shift.
• Inspect the hardened punch and die cutting edges for micro-chipping every two weeks of service.
• Check hydraulic cylinder seals for weeping oil around the ram collar twice per year.
