Compact Cordless Cutoff Saws

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.

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.

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

Brushless Motor—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.

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

Brake—Saws with a brake come to a stop when you release the trigger, so you can quickly reposition your tool and move on to your next cut.

Cordless Portable Cutoff Saws

Cut through metal, reinforced concrete, and other hard materials anywhere on your site. These saws weigh less than 15 lbs. and run on batteries, so they’re often pulled out for jobs where you don’t have access to an outlet. To keep the abrasive wheel cool when cutting through concrete, masonry, or stone, connect these saws to a water supply. Cutting with water also reduces dust in the air, making cleanup easier.

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

Warning: You must use wheels with a greater rpm rating than the no-load rpm of your saw.

Milwaukee—Milwaukee saws have a brake that brings the wheel to a stop when you release the trigger, so you can quickly reposition your workpiece and move to your next cut. These saws also connect to a free downloadable app, Milwaukee One-Key. From your smartphone or tablet, you can track your tool, monitor usage, and get notifications for maintenance.

Indicator Light—All saws have an indicator light to tell you when you’re pushing too hard, which can cause kickback.
