Makita U.S.A., Inc., manufacturer of high-quality professional tools and accessories, announced the world’s first compact industrial 4- ½-inch / 5-inch angle grinders with non-removable guards (models GA4553R and GA5053R).
The 4-1/2 inch and 4-1/2-inch / 5-inch Paddle Switch Angle Grinders with non-removable guards can be used in concrete/masonry and metal applications. The non-removable guard is permanently attached but could quickly be rotated for adjustment by the push of a lever. A cutting guard cover is available for any metal cutting applications.
Additional features reportedly include anti-restart protection and a tethering loop. Anti-restart protection is an electronic feature engineered to prevent accidental motor start-up in the event that the grinder is left in the on-power switch position after a power disruption.
The tethering loop at the tail-end of the grinder provides a secure connection for attaching a lanyard while operating the grinder at heights or on a lift, and this feature reportedly meets ANSI/ISEA 121-2018 standards.
The angle grinders feature a powerful 11 AMP motor that delivers more output at 11,000 RPM. This new motor design delivers high levels of power for high-demand applications. For added durability, armature copper coils are epoxy-protected with a zig-zag pattern to protect against debris and to sufficiently dissipate heat to prevent overheating.
The ergonomics of the grinders have been redesigned. Large paddle switches provide multiple press points for power-start. The narrower barrel grip design could allow for increased hand comfort while operating and reduced operator fatigue.
In addition to the GA4553R and GA5053R, another new compact industrial angle grinder is launching, the 4-1/2-inch / 5-inch Paddle Switch Angle Grinder with AC/DC Switch (model GA5052). It also features an 11 AMP motor that delivers 11,000 RPM, as well as an integrated tethering loop and standard removable guard with quick push button adjustment.
