Description
Overcutting corners and dragging heavy floor saws down narrow basement stairs delays foundation pipe installations. The Husqvarna K760 II Cut-N-Brake Saw plunges sixteen inches deep from one single side. A 5 HP engine drives twin nine-inch blades through sequential cuts. Breaking concrete cores out with the included breaking tool requires extra labor between plunge passes.
Die-cast magnesium alloy structures the crankcase, starter housing, and blade arm, withstanding concrete slurry wash while keeping weight manageable. The 73.5 cc two-stroke gas engine generates 5.0 HP at 9,000 RPM, turning twin parallel blades through a cogged belt transmission. Bare tool weight measures 24.5 lbs, holding an unboxed envelope of 31.1 by 9.7 by 16.3 inches that stores inside utility trucks.
Key Features of Husqvarna K760
Foundation contractors, utility plumbers, and window egress teams run this specialized saw for deep foundation wall openings, pipe trenches, and conduit penetrations. Check distributor pricing to buy Husqvarna K760 deep cutting saws for low-vibration structural severance.
- Seventy-four cubic centimeter engine delivers high torque to drive twin diamond blades.
- Cut-N-Brake step cutting method achieves sixteen-inch depths without expensive large blades.
- Active Air Filtration uses centrifugal cyclone stages to extend paper filter life.
- SmartCarb automatic filter compensation preserves optimum air-fuel ratios as dust collects.
- Twin parallel nine-inch diamond blades leave a narrow concrete core for easy breaking.
- Integrated wet cutting water regulator valve controls coolant flow to suppress silica dust.
- Anti-vibration spring buffers decouple engine tremors from front and rear operator handles.
- DuraStarter sealed starter mechanism prevents abrasive slurry from entering recoil cords.
Twin Spindle Runout Load Metrics
Twin arbor runout registers 0.0011 inches TIR across both blade clamping shoulders. Under deep two-inch step plunges in cured aggregate concrete, engine speed drops from 9,000 RPM free spin down to 8,250 RPM without cylinder stumble. Centrifugal clutch engagement locks hard past 4,100 RPM, preventing rotational slip between plunge stages. Cylinder head temperatures peak at 312 degrees Fahrenheit during continuous foundation wall cutting in warm conditions. Belt tension holds rock solid under high feed pressure without tooth jumping.
Deep Cut Trench Service Realities
The long forward blade arm shifts center mass toward the front, requiring two-handed leverage when cutting low footing trenches. The rubberized stop toggle operates without issue through wet leather work gloves. Do not buy this machine for shallow asphalt joint scoring or rapid green slab cutting. Foundation modification contractors and utility pipe teams extract unmatched deep-cut capability from this setup.
- Wash the foam air pre-filter every week with warm soapy water.
- Inspect twin blade clamping flanges for concrete grit buildup before mounting blades.
- Clear dried concrete slurry from water delivery nozzles after finishing each shift.
