24" Diamond Dot Magnetic Backing Disc

Overview

The 24" Diamond Dot Magnetic Backing Disc is a high-performance electroplated diamond patterning disc engineered for large-scale lapidary flat laps, commercial glass processing equipment, and precision stone surface leveling machines. Featuring an advanced diamond dot pattern electroplated onto a rust-resistant flexible spring steel base with a magnetic backing, this disc provides exceptional slurry clearance, aggressive material removal, and quick tool-free disc changes.

Key Features

• Diamond Dot Matrix: Raised dot patterning creates continuous channels for instant swarf and water slurry evacuation, preventing hydroplaning, disc clogging, and premature diamond glazing.
• Magnetic Backing System: Effortlessly mounts to magnetic master laps without adhesives, screws, or clamping rings, enabling swift multi-stage grit transitions.
• Rust-Resistant Spring Steel Core: Flexible yet resilient spring steel base ensures flat, vibration-free contact across the large 24-inch grinding area.
• Wide Grit Range (45 to 600 Grit): Accommodates heavy stock removal, rapid surface roughing, intermediate smoothing, and pre-polish prep.
• Wet Grinding Efficiency: Optimized for flood-coolant or continuous drip operation to prolong diamond life and maintain a dust-free work environment.

Applications

• Aggressive flattening and stock removal on large gemstone slabs, agates, and quartz
• Cold glass leveling, architectural glass edge smoothing, and beveling
• Flattening ceramic, porcelain, and refractory tile bases
• Pre-polishing and surfacing large mineral specimens and petrified wood slabs

Technical Specifications

• Disc Diameter: 24 inches (600 mm)
• Abrasive Pattern: Electroplated Diamond Dots
• Backing: Magnetic Backing
• Core Material: Flexible Spring Steel Plate
• Available Grits: 45, 60, 80, 100, 140, 200, 270, 325, 600 Grit
• Compatibility: 24-inch flat lap machines (Hi-Tech, Covington, Inland, Lortone, and Hans flat laps)

Operating Guidelines

• Always grind with a steady flow of water to lubricate the disc face and clear debris through the dot channels.
• Use light to moderate, uniform downward pressure; avoid excessive point pressure that can distort the flexible plate.
• Rinse the disc and master lap thoroughly between grit steps to avoid grit contamination.
• Wipe dry and store flat after use to maintain magnetic backing strength and plate flatness.
