Husqvarna K 770 Gas Cut-Off Saw – 14" Power Cutter

Husqvarna K 770 Gas Cut-Off Saw: Built for Concrete, Asphalt and Masonry

The Husqvarna K 770 is a 14" gas-powered power cutter (cut-off saw) for contractors who cut concrete, asphalt, block, brick, pavers, curbstone, stone and metal pipe every day. It is the successor to the K 760 and keeps the same light, compact layout while adding the SmartTension™ belt system, a stronger cutting arm and lower vibration. Use it handheld for openings, trenches and demolition, or on the Husqvarna KV 7 cart for straight road cuts.

Why Contractors Choose the K 770

5 hp X-Torq® engine, 22.4 lb

The 73.5cc two-stroke X-Torq® engine delivers 5 hp (3.7 kW) with up to 20% lower fuel consumption and 75% lower emissions than a conventional two-stroke. At 22.4 lb without blade, the power-to-weight ratio is the best in its class.

SmartTension™ semi-automatic belt tensioning

Correct belt tension means full power to the blade, less wear and maximum belt life. SmartTension™ sets it for you, so there is no guesswork and no slipping belt mid-cut.

Active Air Filtration™ and DuraStarter™

Centrifugal air cleaning removes most dust before it reaches the filter, giving up to a year between filter changes. The dust-sealed DuraStarter™ and durable cord mean reliable pulls in any weather.

Vibration under 2.5 m/s²

Front-handle vibration of 2.0 m/s² and rear of 2.3 m/s² let operators run full shifts without vibration-exposure limits becoming an issue.

Reversible cutting arm and sealed transmission

Flip the arm to cut flush against walls or the ground. The fully sealed belt transmission keeps cutting dust out, extending belt and bearing life.

Wet or dry cutting

The integrated water kit uses less water and produces less slurry. For dry cutting, the guard design handles dust effectively and accepts a 2" vacuum hose.

5" with a 14" blade; 4" with a 12" blade.

Can the K 770 cut wet and dry?

Yes. It includes a water kit for wet cutting and accepts a vacuum attachment for dry cutting with a dry-rated diamond blade.

Does the K 770 come with a blade?
