Air 4-1/2" Right Angle Grinders - 5/8-11 Ext. Thread

Standard & Long Body Models Powerful Without Excessive Weight

Unlike similar looking right angle sanders, grinders are equipped with a safety guard - making them suitable for use with bonded wheels and discs.
3M grinders are high quality, lightweight tools with high air-use efficiency - generating surprising power and smooth operation.
The guard rotates 360, and can be repositioned for better visibility of the work surface, and easier access in hard to reach areas.
Use for general metal fabrication applications grinding, blending, weld leveling, metal prep, and pipe notching.
The extended version (11-1/2" long) has a 3 inch longer neck than the standard model (8-1/2"), and is ideal for hard-to-reach areas.
Use of the included side grip handle, for either left or right hand, places the operators hand further from the grinding area for safer operation, and provides more leverage for control.
Safety guard allows use of tool with bonded wheels, as well as fibre discs, flap discs, and Scotch-Brite surface conditioning discs.
Tool has a 3/8" air inlet, but includes a 3/8" to 1/4" reducer allowing for use of a variety of air inlet plugs
However, for optimal tool performance, we recommend using fittings whose internal diameters maintain the full air flow.
1 horsepower, high-torque motor allows higher pressure without stalling the tool
Polymer encased metal motor housing provides stable temperature, for more operator comfort
3M gripping material molded into tool housing allows greater control with less gripping force
Optimal airflow for the rpms specified = 35 SCFM
Precision steel spline coupler provides accurate motor alignment and improved smoothness
Right angle steel gear head with grease fitting helps extend gear life
