The 11 AMP motor with variable speed (0-2,800 SPM) has a 1-1/8 inch blade stroke for efficient cutting. It is ideal for metal cutting, wood cutting, drywall and plaster, plastics, remodeling, and demolition applications.The JR3050T also features an internal dust blower system to clear debris from the line of cut for improved visibility, with a heavy-duty shoe and “tool-less” blade change for fast blade change and removal. The JR3050T is engineered with all ball and needle bearings for longer tool life, and a durable body design with a protective rubber boot to seal the motor and bearings from dust and debris.
