Wolfcraft 5475000 Sierra de corona bimetálica 74 mm

Electricians, plumbers and carpenters rely on this Wolfcraft 5475000 hole saw when they need a clean 74 mm opening in wood, drywall, plastic or non-ferrous metal. The bi-metal construction pairs a hardened HSS cutting edge with a tough alloy steel body, so the teeth stay sharp through repeated cuts in renovation and installation work.

Key specifications

• Diameter: 74 mm
• Material: Bi-metal (HSS teeth, special alloy steel body)
• Cutting depth: 38 mm
• Tooth type: Variable tooth pitch (Vario-verzahnung)
• Mounting thread: 5/8"-18 UNF
• Compatible with Wolfcraft arbors 5460000, 5461000, 5462000

Why choose it

The welded HSS cutting edge gives long service life, and the optimized chip removal keeps the cut cool and fast. High concentricity means the hole lands exactly where you aim, reducing rework on visible surfaces.

Ideal use cases

• Cutting holes for downlights in plasterboard ceilings
• Drilling cable pass-throughs in wooden studs
• Making openings for pipework in plastic panels
• Creating large holes in non-ferrous metals like aluminium or copper

Good to know

The hole saw is sold individually and requires a compatible arbor and pilot drill (not included). Use a corded or cordless drill with sufficient torque for the 74 mm diameter.
