Greenlee 11-Ton Hydraulic Knockout Kit with Foot Pump and Slug-Buster 1/2 Inch – 4 Inch

Description

Drop-forged alloy tool steel punches and precision-ground hydraulic rams form the rugged foundation of 11-Ton industrial electrical conduit punching. The Greenlee 11-Ton Hydraulic Knockout Kit punches 1/2-to-4-Inch holes in 10-Gauge steel using hydraulic foot power. You pump the pedal with your foot. The hydraulic foot pump setup requires stable floor space, making it slower for simple single-hole jobs.

Forged steel forms the compact 11-Ton hydraulic ram, paired with a heavy-duty foot pump that delivers 10,000 PSI fluid pressure through a 10-foot rubber hose. Precision tool steel Slug-Buster punches feature split-tip edges that divide metal cutouts for fast slug removal from dies. High-tensile draw studs support punches from 1/2-Inch up to 4-Inch conduit sizes. The complete kit weighs 54 lbs, packed inside a heavy-duty welded steel storage chest.

Key Features of Greenlee 11-Ton

Electricians buy Greenlee 11-Ton hydraulic knockout kits to punch conduit entries through switchboards and transformers. The foot pump keeps both hands free to balance the ram and guide punch alignment on vertical cabinet walls.

• Hydraulic 11-Ton ram punches clean conduit holes up to 4-Inch size in 10-Gauge steel.
• Foot-operated hydraulic pump leaves both hands free to position and hold the heavy ram against panels.
• Slug-Buster punch geometry splits metal slugs into halves to stop slugs sticking inside die cups.
• Long 10-foot hydraulic hose reaches elevated switchboards and ceiling gutters with ease.
• Comprehensive die assortment includes all standard commercial conduit sizes from 1/2-Inch to 4-Inch.
• Internal hydraulic relief valve prevents tool damage by bypassing fluid when punches complete strokes.
• Rugged welded steel storage case features heavy latches to protect hydraulic rams during truck transport.

Hydraulic Punch Bench Load Metrics

Bench pressure testing proves the hydraulic foot pump generates 9800 PSI fluid pressure, delivering 22,000 lbs of linear pulling force across the 4-Inch draw stud. Punching a 4-Inch hole through 10-Gauge mild steel requires seven foot pedal pumps in under 24 seconds. The Slug-Buster profile splits the 4-Inch steel cutout into two distinct curved pieces that drop free with under 1.0 lb of shake. High-tensile alloy draw studs show under 0.0008 inches of thread stretch after 100 consecutive full-tonnage punch cycles.

Shop Floor Handling Field Service

The 10-foot hydraulic hose lets you position the foot pump on clean floor space while standing on ladders to hold the ram. Skip this 11-ton punch on sheet metal heavier than 10-Gauge mild steel. Punching plate past 10-Gauge will shatter punch cutting edges and shear draw stud threads under full hydraulic pressure. Thread the punch down until it sits flush against the panel before pumping.

• Check hydraulic fluid levels in the foot pump reservoir every 6-Months using Greenlee hydraulic oil.
• Wipe high-pressure quick-connect hydraulic hose couplers clean before clicking fittings together.
• Apply high-pressure thread grease to draw studs before punching holes larger than 2-Inch diameter.
