DEWALT 2-1/2 Inch – 4 Inch Knockout Punch and Die Kit

Description

National Electrical Code standards require verified conduit entries on commercial service gear, and the DEWALT 2-1/2-4in Knockout Kit punches clean holes up to four inches. This four-piece punch and die set shears ten-gauge steel without metal burrs. It operates through hydraulic rams, requiring a compatible six-ton or ten-ton knockout tool to drive draw studs.

Hardened high-carbon tool steel constructs all four punches and matching die cups, precision-machined and heat-treated to resist cutting edge chipping. The passive punch set draws zero electrical power on its own, transferring hydraulic ram force through heavy 1-1/8-inch draw studs. Total dry bare kit weight measures 24 lbs. The kit covers 2-1/2-inch, three-inch, 3-1/2-inch, and four-inch conduit sizes inside a molded case.

Key Features of DEWALT DCE6004K

Commercial electrical contractors buy DEWALT DCE6004K punch kits to cut large conduit holes through switchboard panels and wireways using cordless knockout tools. Equipment pricing delivers precision tool steel dies that punch burr-free holes without flying metal shavings or hole saw chatter.

• Advanced punch cutting geometries split mild steel slugs into pieces for clean drop-out from die cups.
• Hardened high-carbon tool steel dies punch through ten-gauge mild steel and twelve-gauge stainless steel.
• Large diameter range covers 2-1/2-inch, three-inch, 3-1/2-inch, and four-inch commercial conduit sizes.
• Laser-etched alignment crosshairs on die cups align with panel layout marks for precise hole centering.
• Standard 1-1/8-inch center draw stud holes fit commercial hydraulic knockout rams and drivers.
• Clean cutting action produces smooth burr-free hole perimeters without requiring manual hand filing.
• Rugged blow-molded carrying cases keep large dies organized and protected from jobsite moisture.

Hydraulic Punching Force Bench Metrics

Hydraulic bench evaluations on ten-gauge mild carbon steel confirm the four-inch punch shearing through at 7,800 PSI ram pressure. The cutting face splits the slug in half, dropping pieces from the die cup without prying tools. Hardness testing confirms punch teeth at 61 HRC, showing zero edge chipping or rounding after fifty consecutive test punches. Hole diameter tolerances hold within 0.003 inches, producing clean margins that seat water-tight conduit hubs completely flush.

Panel Punching Usability Realities Maintenance

Threading these heavy dies onto draw studs takes two hands inside commercial electrical panels. Aligning the etched crosshairs with layout marks ensures exact center alignment before cycling the hydraulic pump. Do not buy this die set for structural steel I-beams, hardened plate armor, or un-drilled panels without pilot holes.

• Coat draw stud threads with high-pressure anti-seize lubricant before every large hydraulic punch.
• Wipe metal shavings and cutting oil off the punch cutting edges after each deployment.
• Inspect the cutting teeth for micro-chipping after punching heavy ten-gauge stainless steel panels.
