Wolfcraft 4151000 Circle Cutter for Drills, 30-120 mm Cutting Diameter, 30 mm Max Depth, HSS Blades, 8 mm Shank

Cut clean, accurate circles from 30 to 120 mm in diameter with this Wolfcraft circle cutter. Unlike fixed-size hole saws, the stepless scale lets you dial in any diameter within the range and lock it with the included hex key. Two HSS blades slice through wood, plywood, plasterboard, plastic, laminate, and acrylic glass up to 30 mm thick, while the integrated centering drill keeps the cutter on track. The 8 mm shank fits standard drill chucks, and the 500 RPM maximum speed works with both corded and cordless drills.

Highlights

• Adjustable cutting diameter from 30 to 120 mm with stepless scale
• Two HSS cutting blades for clean results in wood, plastic, laminate, and more
• Centering drill bit included for precise positioning
• 8 mm shank fits most drill chucks
• Maximum material thickness: 30 mm

In daily use

Mark your center point, drill a pilot hole with the centering bit, then set the desired radius on the scale and tighten the hex key. The cutter works best at speeds up to 500 RPM—reduce speed for harder materials or larger diameters. For deep cuts, clear chips frequently to avoid overheating the blades.
