- Fast Cutting Carbide-tipped teeth with optimized geometry provide faster cutting speed and smoother edges on ceiling panels and drywall, outperforming standard hole saws. - HSS Bi-Metal Construction Made with high speed steel and bi-metal design for high load capacity and improved durability. Delivers better performance and greater cut resistance than comparable options. - Easy to Use Non-binding design reduces jamming, delivering clean edges and smooth cuts. An integrated spring ejects the cut-out plug automatically after drilling. - Upgraded Design Ultra-sharp serrations and thicker wall enhance durability and reduce tooth loss. Sharper cutting teeth enable faster material removal, extending the life of the hole saw. - Practical Applications Perfect for creating holes in ceiling panels and drywall for lighting fixtures, vents, or wiring access. Suitable for installation work in walls and ceilings during remodeling or renovation projects. Useful for electrical, plumbing, or HVAC installations where clean, precise holes are required in drywall or similar materials.
