Project Ideas
Business
On‑Site Panel Knockout Service
Offer a mobile service to add 4 in conduit entries to existing electrical panels and enclosures using the DEWALT DCE600 and this die. Market to electricians, facilities, and MRO teams; bill per hole plus setup, with fast, burr‑minimal results thanks to the die’s alignment crosshairs.
Custom Enclosure Mod Shop
Provide quick‑turn punching for OEMs and integrators: 4 in knockouts in mild or stainless backplates, solar combiner boxes, control panels, and junction boxes (within gauge limits). Accept CAD or templates, verify centerlines with the die’s crosshairs, and upsell powder coat and labeling.
HVAC/Plumbing Penetration Subcontracting
Subcontract to mechanical contractors for clean 4 in penetrations in sheet metal ductwork, commercial hoods, and equipment skins. The embedded magnets speed alignment on mild steel plenums, and stainless capability covers kitchen and food‑service applications.
Brewery/Food‑Service Retrofits
Add 4 in sanitary pass‑throughs, trash chutes, or service ports to stainless worktables, sinks, and light‑gauge vessels (up to 12 ga). Partner with breweries and restaurants for in‑place modifications with minimal downtime; offer welded collars or ferrules as add‑ons.
Rental + Hands‑On Mini Training
Rent the DEWALT hydraulic knockout tool with the 4 in die for weekend or project use. Include a short safety and alignment tutorial, gauge limit guide, and a deburring kit. Tiered pricing by day/week with a refundable deposit; upsell additional die sizes.
Creative
Industrial Porthole Wall Art
Punch perfectly aligned 4 in circles in 10 ga mild steel sheets to create geometric or wave‑pattern panels. Use the embedded magnets and crosshairs to grid the layout, then backlight the openings with LED strips or mount frosted acrylic disks behind the holes for a modern, industrial art piece.
Smoker/Fire Pit Air Intakes
Build a drum smoker or fire pit and use clean 4 in knockouts as adjustable intake and exhaust ports. Add sliding dampers or swivel covers over the holes. For heat-prone parts, use up to 12 ga stainless steel; the die’s crosshairs help align multiple ports evenly around the shell.
Perforated Pendant Lights
Form lamp shades from mild steel and punch repeating 4 in apertures for dramatic light patterns. The magnets hold the die to curved steel sections for safer positioning, and the crosshairs ensure symmetrical placement around the shade.
Garden/Hydroponic Lids
Create durable planter or hydroponic reservoir lids with 4 in openings sized for common net cups or access ports. Use stainless up to 12 ga for corrosion resistance; the laser-etched size markings keep setups consistent across multiple lids.
Custom Speaker Baffles
Fabricate metal speaker baffles or acoustic panels with exact 4 in driver cutouts or relief ports. The crosshair alignment lets you mirror left/right layouts precisely, and the clean punch edge reduces finishing work before painting or powder coat.
