In the high-stakes environment of industrial metal fabrication, relying solely on unit price to source wholesale grinding wheels is a critical procurement error. When outfitting a shipyard, foundry, or sheet metal shop, the abrasive consumable directly dictates your operational workflow, rework rates, and operator health metrics.
One of the most persistent challenges we see on the factory floor is thermal damage when grinding thin stainless steel panels, closely followed by the tedious removal of heavy surface oxidation. To solve these specific pain points, Fuji Grinding Wheel has engineered the NATTOKU Grinding Disc—a 100% Made in Japan abrasive that brings premium performance to an affordable price point.
The structural integrity and performance of a grinding disc are determined by its manufacturing technology. A vast majority of mass-produced Western abrasives utilize a cold-pressed methodology. These wheels require excess resin to bind the abrasive grains, resulting in a dense, brittle product that glazes over quickly and generates excessive heat.
The NATTOKU series takes a vastly different approach. Engineered as an affordable counterpart to our premium JITAN series, NATTOKU utilizes highly refined P-grade White Aluminum Oxide combined with a single-layer fiberglass mesh.
Through the latest Japanese layered hot-pressing technology, the phenolic resin fuses perfectly with the abrasive. This highly controlled thermal process creates a uniformly porous structure—essentially, a disc that "breathes."
The "breathing" pores actively dissipate heat during operation. Even when grinding ultra-thin stainless steel plates, the NATTOKU disc maintains a low workpiece temperature, completely eliminating heat discoloration (blueing) and the need for expensive rework.
The self-sharpening nature of the P-grade alumina makes it incredibly effective at stripping away surface oxidation, welding scale, and rust. It removes material quickly and smoothly without snagging or glazing.
Abrasive procurement must account for Environmental, Health, and Safety (EHS) standards. Poor-quality wheels pose severe, long-term risks to operators.
True value in B2B procurement is measured through the Total Cost of Ownership (TCO). While the NATTOKU disc delivers performance remarkably close to our flagship JITAN series, it is positioned as a highly affordable alternative.
The uniform resin distribution ensures that the wheel lasts significantly longer than standard cold-pressed discs. The abrasive grains shed only when necessary, maintaining a high Material Removal Rate (MRR) from the first cut to the last. Available in a wide range of diameters—4", 5", 6", and 7" (105mm to 180mm)—it meets the diverse needs of foundries, cast iron post-processing plants, and thin sheet fabricators.
| Procurement Metric | Standard Cold-Pressed Wheels | FUJI NATTOKU (Hot-Pressed) |
|---|---|---|
| Thermal Management | Dense structure traps heat; high risk of burning thin stainless steel. | Porous structure dissipates heat; guarantees burn-free grinding. |
| Dust & Debris | Excess resin causes heavy dust and dangerous flying fragments. | Optimized bond reduces dust; highly safe for operators. |
| Longevity & TCO | Glazes over quickly, requiring frequent replacements. | Self-sharpening design extends lifespan; highly cost-effective. |
NATTOKU utilizes Japanese hot-pressing technology with P-grade White Aluminum Oxide. This creates a porous, 'breathing' structure that dissipates heat rapidly, preventing burn marks on thin stainless steel while requiring less resin, which reduces flying debris.
Yes. It is designed as an affordable, highly economical alternative to our premium JITAN series. It offers extended lifespan and self-sharpening properties, significantly lowering the Total Cost of Ownership (TCO) for bulk B2B procurement.
The disc features an elastic structure that minimizes vibration, helping prevent Hand-Arm Vibration Syndrome (HAVS). Additionally, its optimized resin-to-grain ratio produces significantly less metal dust during scale removal, reducing the risk of pneumoconiosis.
