GK POWER Silicon Carbide Discs

GK POWER Silicon Carbide Abrasive Sanding Discs | Stone, Concrete & Cast Iron

High-Performance Surface Levelling, Deburring, and Fine Finishing

The GK POWER Silicon Carbide (SiC) Series is a professional range of heavy-duty fiber backing sanding discs designed for aggressive material removal and surface refinement on extremely hard, brittle surfaces. Utilizing premium Silicon Carbide grains (designated by the P-grit rating), these discs outperform standard aluminum oxide when working on non-metallic masonry and dense ferrous metals. They provide a rapid scratch pattern and cool running temperatures, making them the ultimate choice for smoothing down concrete, leveling stone joints, and cleaning up rough iron castings.

Technical Specifications & Range

Key Features:

• Premium Silicon Carbide (SiC) Abrasive: Silicon carbide grains are incredibly sharp and fracture easily during use. This self-sharpening action prevents "clogging" or glazing, ensuring the disc maintains a consistent, aggressive bite into dense surfaces.

• Heavy-Duty Fiber Backing: Built on a highly rigid vulcanized fiber backing that provides excellent structural support under heavy downward pressure, ensuring even wear and a flat finish.

• Extreme Material Compatibility: Specifically engineered for materials where standard metal discs fail or clog, including Concrete, Granite, Marble, Terrazzo, Natural Stone, Glass, and Cast Iron.

• Cooler Surface Temperatures: The open structure of the grain coating allows dust to escape quickly, preventing heat buildup that could cause structural cracking in delicate natural stones.

• From Roughing to Finishing: The range covers coarse P36/P40 grits for rapid reshaping and flattening, down to P60 for a smooth, scratch-free surface ready for final sealing or polishing.

Technical Specifications:

• Brand: GK POWER

• Abrasive Mineral: Silicon Carbide (SiC)

• Bore Hole: 22.2mm (Standard)

• Backing Material: Reinforced Vulcanized Fiber

Safety & Usage Instructions:

• Backing Pad Required: These are fiber sanding discs and must be mounted on a matching 115mm or 125mm flexible rubber or rigid plastic backing pad before being secured to the angle grinder spindle.

• Angle of Operation: Maintain a shallow angle of 10° to 15° relative to the workpiece. Grinding completely flat can cause gouging, while grinding too steeply will wear out the edge prematurely.

• Speed Verification: Ensure your angle grinder's maximum operating speed does not exceed the structural limits of the disc and backing pad assembly.

• Mandatory PPE: Working on stone and iron produces high-velocity sparks and toxic crystalline silica dust. A P3-rated respirator mask, safety goggles, heavy gloves, and hearing protection are strictly required.
