The HS-420 hand saw is a heavy duty, medium RPM Hand Saw designed to cut completely through 8 inch thick walls. It is powered by a sealed 7 1/2 horsepower water cooled, 400 HZ motor. The motor has a thermal overload shut-off for protection and a slip clutch for maximum gear life and operator safety. The saw has a one inch round arbor to permit the use of any standard diamond blade. It has an internal built in slip clutch for protection.
The primary use for the HS-420 is production hand sawing of concrete between 5” and 8¼” deep. It is often used as a substitute for special slab sawing jobs where set-up is difficult or access to the job is limited.
This saw is capable of 100% rated power hundreds of feet from its power source, and is one of the most versatile hand tools developed for the concrete cutting industry.
