Wolfcraft 3753000 luknjač za pločevino 32 mm

Electricians and plumbers working on sheet metal enclosures or control panels need clean, burr-free holes for cable glands and conduits. The Wolfcraft 3753000 punches a precise 32 mm diameter hole in steel, stainless steel, non-ferrous metals, and plastics using a manual screw-driven mechanism. A 10.5 mm pilot hole and a wrench or ratchet are all that is required.

Key specifications

• Hole diameter: 32 mm
• Max material thickness: 2.0 mm steel (up to 400 N/mm²), 1.0 mm stainless steel (up to 600 N/mm²), 2.5 mm non-ferrous metals, 2.5 mm plastics
• Operation: Manual screw-driven, hexagon drive for wrench or ratchet
• Required pilot hole: 10.5 mm
• Material: Hardened tool steel punch and die

Why choose it

Unlike twist drills, this punch produces a clean, burr-free hole without deforming thin sheet metal. The hardened tool steel construction withstands repeated use, and the screw-driven design gives you full control over the cutting force. It works with a standard wrench or ratchet, so no special tools are needed.

Ideal use cases

• Knockout holes in electrical cabinets for cable entry
• Plumbing and HVAC sheet metal work
• Fabrication with aluminium, brass, or plastic panels

Good to know

The set includes the punch, die, and draw bolt. Always drill a 10.5 mm pilot hole before punching, and ensure the material is securely clamped. For best results on stainless steel, use cutting oil.
