Built for Hardscaping, Road Work & Masonry Contractors

Whether you're cutting asphalt for cable burial, slicing curbstones, or making precision floor and wall cuts, the K770 is engineered to keep up with your crew. Its reversible cutting arm lets you cut closer to walls and the ground, reducing rework and keeping your job site clean. Pair it with the KV7 trolley for straight or curved track cutting on road jobs.

Available in 12" and 14" blade configurations. Blade not included.

SmartTension Belt System – Optimal Power, Minimal Wear

The semi-automatic SmartTension system eliminates the guesswork of belt tensioning. It prevents under- and over-tensioning automatically, ensuring maximum power transmission, longer belt life, and fewer mid-job breakdowns — so your crew stays productive.

Exceptionally Low Vibrations – All-Day Operator Comfort

Vibrations below 2.5 m/s² at both handles reduce operator fatigue on extended cuts. Less fatigue means fewer errors, safer job sites, and more cuts per shift — a direct impact on your project margins.

Active Air Filtration & DuraStarter – Long Service Intervals

The Poly-V belt, maintenance-free DuraStarter, and Active Air Filtration system are engineered to extend service intervals and reduce downtime. Spend more time cutting and less time in the shop.
