BACHMANN 928.900 Serra copo 79 mm para madeira e plástico

Cutting large, clean holes in wood and plastic often means choosing between a cheap blade that wanders or a heavy industrial set that costs more than the job is worth. The BACHMANN 928.900 hole saw strikes a different balance: a 79 mm cutting diameter, coarse tooth geometry, and high carbon steel construction that stays sharp through repeated use, all in a single, no-fuss accessory. It fits any standard arbor, so you can pair it with the drill you already own and start working immediately.

Highlights

• 79 mm cutting diameter for cable pass-throughs, pipe openings, and fixture holes
• Optimized for wood and plastic — clean entry and exit without melting or splintering
• High carbon steel body resists dulling and maintains concentricity
• Coarse tooth design clears chips quickly, reducing heat and binding
• Compatible with standard hole saw arbors (sold separately)
• Compact 60 mm overall length fits tight spaces between studs and joists

In daily use

On a job site or in a workshop, this hole saw proves its worth when you need a 79 mm opening in plywood, MDF, PVC, or acrylic. The coarse teeth bite steadily without grabbing, and the open gullets eject waste efficiently, so you can drill at a consistent speed without stopping to clear the kerf. Because it is a single hole saw rather than a full kit, you avoid paying for sizes you will never use — yet the quality is far above disposable import blades. Keep a spare arbor on hand and you can swap between sizes in seconds.
