Advanced Technology & Core Benefits
SmartTension™ System
-
Delivers fast, accurate belt tensioning with a single turn, eliminating under/over-tightening and reducing maintenance. Maintains consistent power transfer even in repeated cuts and tough aggregates.
LowVib™ Vibration Isolation
-
Award-winning vibration-dampening handle system reduces operator fatigue and enhances control, permitting longer and safer operation with minimal risk of hand-arm injuries.
Active Air Filtration™ & DuraStarter™
-
Three-stage centrifugal + paper filter system keeps intake clean longer. Maintenance-free DuraStarter ensures years of reliable starts and minimizes unexpected downtime.
Heavy-Duty Crankcase
-
New cast magnesium crankcase uses a three-bolt connection to resist deflection and boost rigidity. Improves blade stability and longevity for precise cutting—especially in high-pressure, angled, or deep cuts.
Wet/Dry Cutting Ready
-
Built-in wet cutting port with optional WT15 water tank or direct hose connection drastically reduces dust and extends blade life—fully compliant with modern silica regulations.
Versatile Application Range
-
The K770 handles every site material: reinforced concrete, curbstone, bricks, iron pipes, asphalt repair, stone, tile, steel, and more. Integrated reversible cutting head lets users work flush with sidewalk curbs or close to wall/floor joints.
