The Viking hole saw set S-310LK offers a comprehensive cutting solution for professional and industrial applications with a versatile range of seven hole saw diameters from 22 mm to 78 mm. This complete set includes two MPD4S multipurpose drill bits and special adapters (71MH, M44, M50, M30S) for various mounting systems and machine interfaces. The hole saw diameters are precisely calibrated to 22 mm, 57 mm, 62 mm, 65 mm, 68 mm, 74 mm, and 78 mm, providing flexibility for different cutting requirements across various materials. Made from high-quality bi-metal materials, these hole saws maintain sharp cutting edges during prolonged use while being resistant to heat build-up and material fatigue. The cutting teeth are designed with optimized geometry for clean, precise cuts in wood, plastic, metal, and composite materials. The MPD4S centering drill bits feature reinforced tips for accurate centering and stable guidance during the cutting process. This set is compatible with standard drills, magnetic drills, and handheld power tools, making it suitable for construction work, plumbing installation, electrical installation, and metalworking. The adapters incorporate quick-change features for efficient tool changes and secure grip to prevent slipping during operation. Each component meets industrial standards for dimensional accuracy and cutting performance, ensuring consistent results across diverse applications. The storage box systematically organizes all components and protects the cutting edges from damage during transport and storage. This hole saw system represents the successor model to previous Viking cutting tool configurations and integrates improved material composition and optimized tooth geometry for extended lifespan and reduced cutting resistance.
