Backing Flange - Milwaukee Electric Tools

The Milwaukee 43-34-3000 Backing Flange is a genuine OEM component designed for compatible Milwaukee angle grinders, serving as the critical inner clamping face for securely mounting grinding and cutting wheels. Also known as an inner flange, this professional-grade part ensures proper wheel seating and contributes to safe, efficient operation in demanding automotive and industrial environments. It works in conjunction with the outer flange nut to create the necessary friction grip, holding the abrasive wheel firmly to the grinder's spindle during use.

Key Features

• Genuine OEM Component: This is an authentic Milwaukee Electric Tools part, ensuring precise fitment and performance with compatible tools.
• Secure Wheel Retention: Designed to provide the inner clamping face, it firmly sandwiches the grinding wheel to the spindle, preventing slippage during operation.
• Optimized Pressure Distribution: The flat clamping face is engineered to apply uniform pressure across the wheel hub, a critical factor in preventing premature wheel cracking from uneven clamping stress.
• Durable Construction: Manufactured from robust steel, this backing flange is built to withstand the rigors of heavy-duty grinding tasks and deliver long-lasting reliability.
• Enhanced Operator Safety: A perfectly flat and undamaged backing flange is essential for safe operation. Prompt replacement of a bent, cracked, or compromised flange is crucial to maintain tool integrity and user safety.
• Specific Compatibility: This backing flange is confirmed to fit Milwaukee 2880-20 and 2881-20 angle grinders.

Applications

The Milwaukee 43-34-3000 Backing Flange is an essential replacement part for professional technicians and mechanics maintaining Milwaukee angle grinders. It is critical for restoring optimal and safe function to grinding tools used in metal fabrication, automotive repair, construction, and other industrial applications where abrasive cutting and grinding are performed. Regular inspection and replacement of worn or damaged backing flanges are vital maintenance procedures to ensure peak performance and operator safety.
