4-7 Inch M10/M14 Angle Grinder Fiber Disc Backing Pad 12200 RPM Heavy Duty Sanding Adapter

Securing fiber sanding discs to your angle grinder shouldn't mean dealing with uneven contact, wobbling discs, or backing pads that warp under heavy pressure. Designed for metal fabricators, automotive body technicians, woodworkers, and industrial welders, this angle grinder fiber disc backing pad delivers rigid support for intense grinding and sanding tasks. Standard flexible backing pads can flex excessively or overheat under friction, causing uneven material removal, gouged surfaces, and premature abrasive disc wear. Crafted from high-strength thermal-resistant composite material with a heavy-duty threaded steel center insert, this M10/M14 disc sandpaper chassis pad withstands high-speed rotation up to 12,200 RPM. Lock your fiber abrasive discs securely, maintain consistent surface contact, and tackle tough surface preparation, rust removal, and weld blending with ease.

Key Features

• High-Speed 12,200 RPM Rating: Engineered to safely withstand the intense rotational speeds of standard pneumatic and electric angle grinders.

• Precision Threaded Steel Arbor Nut: Features standard M10 or M14 heavy-duty steel threads for rock-solid, wobble-free mounting on grinder spindles.

• Rigid Thermal-Resistant Composite Body: High-density construction prevents flexing under heavy pressure and resists friction heat buildup.

• Ribbed Cooling Backing Design: Molded air-channel grooves draw away friction heat to extend the working life of resin fiber sanding discs.

• Multi-Size Disc Compatibility: Available in standard 4-inch, 5-inch, 6-inch, and 7-inch diameters to match your specific grinding setup.

Why Choose Our Angle Grinder Fiber Disc Backing Pad Unlike cheap plastic backing pads that warp under friction heat or crack under heavy leverage, this chassis pad is built for rigorous shop use. The precision-machined locking nut holds fiber discs perfectly centered, eliminating chatter and vibration while maximizing abrasive life. Keep your metalworking and surface refinishing tools running at peak performance.
