Magnetic Backed Plates - Quick-Change Master Lap Plates for Diamond Discs and Polishing PadsOur Magnetic Backed Plates are precision-machined stainless steel and aluminium alloy master lap plates with integrated magnetic layers for instant, tool-free attachment of magnetic-backed diamond discs, resin pads, lapping films, and oxide sheets. The perfectly flat, stable platform minimizes vibration during grinding and polishing, while the corrosion-resistant construction handles continuous wet-lapping environments. Available in full-face and 1/2" center hole variants from 8" to 24" diameter.

Frequently Asked Questions
-
Q: What is the difference between full-face and 1/2" hole variants?
A: Full-face plates have a solid surface across the entire diameter for maximum magnetic holding area. The 1/2" hole variants have a center hole for mounting on spindles with a 1/2" arbor. Choose based on your machine spindle configuration.
-
Q: What mounting option should I choose - PSA sticker, plain, or metal backing plate?
A: PSA sticker plates have a pressure-sensitive adhesive backing for permanent mounting to your machine platen. Plain plates have no backing for custom mounting. Metal backing plates include a full metal backing assembly for the most rigid, stable mounting on professional machines.
-
Q: Are these plates safe for wet-lapping use?
A: Yes - the stainless steel and aluminium alloy construction is fully corrosion-resistant and designed for continuous wet-lapping environments.
