Designed specifically for cutting thick concrete, the K950 chain saw is the only handheld concrete saw that cuts perfectly square corners without over-cuts and makes up to 15-inch-deep cuts from one side, says Partner, and it can navigate tight spaces and cut concrete pipe without cracking it. The diamond-chain saw is best used after a conventional concrete cutter makes the first cuts; the K950 can then be used to reduce overall cutting time. A range of diamond chains in various hardnesses is available.
