9" Heavy-duty Grinding Wheel

JKINGS 9" Production Grinding Master

The 230mm (9-inch) × 6mm grinding disc is the workhorse of heavy industry. Compatible with both large handheld grinders (2,400W+) and stationary chop saws/grinders, it tackles the largest surface areas and thickest material removal tasks in metal processing.

[Dual-Platform Versatility]

Platform A: Handheld 9" Angle Grinders

• Best for: Field work, large structure maintenance, shipyards

• Advantages: Mobility, access to tight spaces on large assemblies

• Requirements: 2,400W+ power, two-handed operation mandatory

Platform B: Stationary Chop Saws / Bench Grinders

• Best for: Production shops, repetitive grinding, small parts batch processing

• Advantages: Superior control, vise holding, higher precision

• Note: Use with reduced pressure—stationary machines have higher torque

[Industrial Applications]

1. Steel Mills & Service Centers

• Conditioning hot-rolled coil edges

• Grinding surface defects from plate

• Cleaning scarfing marks

2. Heavy Machinery Manufacturing

• Grinding large weldments (earthmoving equipment frames)

• Surface prep for large cast bases

• Cleaning flame-cut edges

3. Shipbreaking & Recycling

• Surface cleaning of thick plate for resale

• Grinding cut ends smooth

• Preparing steel for remelting

4. Pipeline Construction

• Grinding longitudinal pipe welds (large diameter)

• Surface prep for field joint coating

• Maintaining line pipe bevels

5. Railroad Maintenance of Way

• Grinding rail ends before welding

• Maintaining switch points

• Grinding frog profiles

[Technical Advantages]

Massive Surface Coverage:

• 415 cm² swept area per revolution

• Grinds 4 meters of 10mm fillet weld per disc (average)

• Reduces labor time by 40% vs. 180mm on large surfaces

Deep Grinding Capability:

• 6mm thickness allows 2-3mm depth of cut per pass (controlled)

• Ideal for leveling mismatched welded plates

• Removes heavy scale and rust in single pass

Extended Service Life:

• 3-layer construction resists side pressure

• Zirconia grain maintains sharpness through full wear

• Typical life: 80-100 minutes continuous grinding

[Safety & Handling]

Critical Safety Requirements:

• Full face shield (impact rated)

• Leather gloves (heat and abrasion resistant)

• Hearing protection (sound level >85dB at 6,000 RPM)

• Dust collection or respirator (metal dust hazard)

• Secure footing (risk of kickback on 9" grinders)
