At less than 3 lbs., these saws are light enough to use with one hand but powerful enough to cut through rebar. Using an abrasive wheel, they’re often used to cut pipes overhead or in tight spaces. Because they run on batteries, they're great for quick jobs when you don't have an air compressor or outlet. A brushless motor optimizes battery usage, so these saws run longer on a single charge. It also enhances longevity—they run cool and have few moving parts that require maintenance.

Connect the dust hood to a dust collector to keep your workspace clean and remove debris from the air. If you're cutting on a flat surface, the dust hood helps stabilize the saw, making it easier to control the depth of your cut.

Some saws include rechargeable batteries. For other saws, batteries and chargers are sold separately.

Saws with reversible wheel rotation let you switch the wheel's direction to control where it sends sparks and debris.

Warning: Use wheels that have a greater rpm rating than the no-load rpm of your saw.
