Greenlee Intellipunch 11 Ton Hydraulic Knockout Slug Buster Set 1/2 – 3 In. Plus 4 In. for Mild Steel

Description

A massive 11-Ton hydraulic ram output delivers 22,000 lbs of linear pulling force across conduit punches from 1/2-Inch up to 4-Inch. The Greenlee Intelli-PUNCH 11-Ton Set 4in punches 10-Gauge steel using 18V battery-hydraulic power. You pull the trigger. Punching large 4-Inch holes in 10-Gauge steel drains battery charge, requiring spare battery packs during full switchboard rough-in shifts.

Forged aluminum alloy forms the 360-Degree rotating driver head, housing an 11-Ton hydraulic pump that pulls with 22,000 lbs of linear force. An 18V lithium battery motor powers the hydraulic piston without external fluid hoses. An onboard OLED screen displays real-time pressure, battery life, and cycle counts. The handheld tool scales at 12.2 lbs with battery loaded, while the complete 1/2-to-4-Inch boxed kit weighs 52 lbs in its heavy polymer transport case.

Key Features of Greenlee Intelli-PUNCH

Electricians buy Greenlee Intelli-PUNCH 11-ton knockout sets to punch commercial conduit entries from 1/2-inch to 4-inch in main panels. Auto-Retract technology senses metal breakthrough to return the piston in a split second, doubling installation speed.

• Powerful 11-Ton battery-hydraulic ram punches 1/2-Inch to 4-Inch conduit holes in 10-Gauge mild steel.
• Auto-Retract technology returns the ram piston the instant the punch breaks through metal panels.
• Onboard OLED display screen shows real-time pressure output, battery charge, and service cycle logs.
• Rotating 360-Degree head swivels to clear internal switchgear busbars and crowded wire gutters.
• Slug-Buster punch geometry splits metal cutouts in half to stop knockouts lodging inside dies.
• Two included 18V lithium-ion batteries provide swappable cordless power for full-day rough-in jobs.
• Heavy molded carrying case organizes the driver, charger, draw studs, and full die assortment.

Battery Hydraulic Bench Load Metrics

Bench strain dynamometer testing proves the 11-Ton battery-hydraulic ram punches a 4-Inch hole through 10-Gauge mild steel in under 7.4 seconds on 18V battery power. The Auto-Retract sensor detects pressure drop at 9200 PSI fluid pressure, retracting the ram piston within 0.8 seconds of punch breakthrough. Punching 50 consecutive 2-Inch holes in commercial NEMA 4X steel enclosures consumes twenty-eight percent of an 18V 4.0Ah battery charge. Tool head temperature remains below 116 degrees Fahrenheit across 20 continuous large-diameter hole cycles.

Shop Floor Handling Field Service

The 360-Degree rotating driver head lets you swing the battery handle away from adjacent conduit runs to prevent hand pinching. Skip this 11-ton punch on plate steel heavier than 10-Gauge mild steel. Over-thick plate will dull the slug-splitting cutting edges and bend the heavy 3/4-inch draw studs under full hydraulic pressure. Thread the punch down flush against the panel before pulling the trigger.

• Apply high-pressure thread grease to draw studs before punching holes larger than 2-Inch diameter.
• Wipe the digital OLED screen clean with a dry microfiber cloth after every work shift.
• Keep battery terminal slots clean of metal filings and dust using dry compressed air.
