FUJI GC masonry cut-off wheels for concrete, brick and stone. Available diameters: 305 mm (12 inch) and 355 mm (14 inch), for compatible stationary cutting machines and handheld petrol power cutters.
In the demanding world of construction, professionals require tools that deliver exceptional reliability. The FUJI 305mm High-Speed Rotation (GC Type) Cut-Off Wheel is the premier choice for contractors working with stone, concrete and brick. This industrial-grade disc operates at speeds up to 100 m/s, featuring a specialized Silicon Carbide (GC) bond formulation engineered specifically for masonry and stone cutting applications.
Whether you are cutting concrete slabs, installing stone flooring, or performing demolition, the G-Type wheel provides the aggressive cutting action and extended life needed for superior results.
For compatible stationary cutting machines and handheld petrol power cutters. Match the wheel diameter, bore, flanges, guard and machine speed to the specific wheel and machine instructions.
| Dimensions (mm) | Thickness | Arbor (Hole) | Grit Type | Max Peripheral Speed | Calculated RPM at 100 m/s | Pack Qty |
|---|---|---|---|---|---|---|
| 305 mm (12") | 4.5 mm | 20.0 / 22.0 / 25.4 / 30.5 mm | GC24R BF | 100 m/s (6,000 m/min) |
Approx. 6,262 RPM | 25 pcs |
| 355 mm (14") | 4.5 mm | 20.0 / 22.0 / 25.4 / 30.5 mm | GC24R BF | 100 m/s (6,000 m/min) |
Approx. 5,380 RPM | 25 pcs |
Speed conversion: 100 m/s equals 6,000 m/min. RPM = 6,000 ÷ (π × diameter in metres). The RPM values above are mathematical conversions, not a substitute for the maximum RPM printed on the wheel. Never exceed the marked wheel limit.
The GC Type wheel is essential for construction and renovation scenarios:
Dust Control: Cutting stone and concrete generates silica dust. Use appropriate dust controls and protective equipment according to the worksite requirements and manufacturer instructions. Water use requires approval for both the wheel and the machine; machine compatibility alone does not establish that the wheel can be used wet.
Inspection: Before mounting, check the disc for cracks. A damaged wheel running at 100m/s is extremely dangerous.
A: No. This GC wheel is intended for concrete, brick, stone and masonry, not steel or railway rails. Railway cutting requires a dedicated railway rail cut-off wheel and a compatible machine.
A: Follow the instructions for the exact wheel and machine. Do not introduce water unless both manufacturers permit it for the intended setup.
A: The listed wheel thickness is 4.5 mm. Check the machine and workpiece requirements when selecting a disc. Thickness does not permit side grinding or lateral loading.
FUJI's commitment to innovation ensures construction professionals receive tools that meet the highest standards. The G-Type cutting disc represents years of R&D specifically targeting the masonry industry.

Choosing the correct abrasive wheel is critical for both operational efficiency and JIS-compliant safety. Fuji Grinding Wheels are engineered with precise technical markings to ensure the perfect match for your specific material and machine requirements.
For professional export markets, always verify the Peripheral Speed (m/s) compatibility. Fuji wheels are designed to exceed JIS Burst Speed factors, but operating at the recommended R.P.M. ensures the longest tool life and cleanest cut.
Note: Mismatched grit or hardness can lead to excessive heat buildup, affecting the workpiece's structural integrity.
Global Maintenance Standard: To maintain the high safety factor of Fuji wheels, avoid exposure to excessive humidity and chemical solvents during storage. Proper care preserves the resinoid bond's strength, crucial for high-load industrial applications.
Fuji products are manufactured following strict Japanese standard process requirements. Every wheel is engineered to meet or exceed JIS (Japanese Industrial Standards), such as JIS R 6242 and B 4051. Our core engineering logic prioritizes maximum operator protection by maintaining safety factors and burst speed capabilities that often surpass the highest industry benchmarks.
| Standard Region | Safety Factor (Burst Multiplier) | Safety Logic & Benchmark |
|---|---|---|
| FUJI (High Precision) | > 2.0x | Engineered to exceed JIS requirements for maximum reliability. |
| Japan (JIS R 6242) | 2.0x | Extreme Safety: A wheel rated at 80m/s must withstand a 160m/s burst test. |
| Europe (EN 12413) | 1.73x | Risk Balanced: Provides high safety redundancy for most industrial apps. |
| USA (ANSI B7.1) | 1.5x | Efficiency Focused: Relies on machine guarding and operational procedures. |

When deploying Fuji high-performance tools in overseas markets, ensure that the regional power grid frequency and voltage match the tool specifications. To maintain the superior burst speed safety of Fuji wheels, store abrasives in a dry, temperate environment. Humidity can degrade the resin bond, potentially lowering the wheel’s resistance to centrifugal forces.
