4" Angle Grinder Pad Holder for Polishing Pads
The Mechanic Centrum PRO 2.0 4" pad holder is a professional-grade angle grinder backing pad designed to securely hold polishing pads in place during grinding and finishing.
Featuring an integrated centering pin, this pad holder prevents slipping, improves alignment, and delivers more consistent polishing results — especially during detailed edge work on porcelain tile and stone.
Secure Polishing Pad Alignment with Centering Pin
This angle grinder pad holder with centering pin ensures:
- Perfect pad alignment during operation
- No slipping or shifting — even when Velcro backing begins to wear
- Consistent polishing performance across the full pad surface
Pad Holder vs Standard Backing Plate — What’s the Difference?
- Standard backing plate — relies on Velcro only; pad can shift as Velcro wears
- Centrum PRO 2.0 (centering pin) — mechanically locks pad in place for greater stability and precision
Removable Centering Pin for Universal Compatibility
The removable centering pin (14.7mm diameter, 2.5mm height) allows:
- Use with different pad hole sizes
- Compatibility with multiple pad brands
- Flexible setup depending on application
Durable Aluminum Construction for Professional Use
Built from high-strength aluminum, this pad holder offers long-lasting durability, stable performance under load, and resistance to wear in demanding jobsite environments.
Compatible with Most 4" Angle Grinders
Fits standard 4" (100mm) angle grinders and most polishing pads across brands.
