The FUJI HD-150 (6") and HD-180 (7") angle grinders are engineered for the toughest industrial applications. Designed for heavy stock removal, weld leveling, and large-scale surface preparation, these tools bridge the gap between standard 4-inch grinders and massive 9-inch units.
Featuring High-Torque Motors (11A - 12.5A) and a robust double-insulated construction, they offer the perfect balance of power and safety for shipyards, foundries, and metal fabrication plants.
The Agile Heavyweight. Ideal for operators who need more cutting depth and surface coverage than a 4" grinder but require a lighter tool than a 7" model.
The Production Powerhouse. Built for maximum removal rates. The 180mm wheel covers large areas quickly, making it the standard choice for heavy welding and foundry work.
| Model | HD-150 | HD-180 / 182 |
|---|---|---|
| Wheel Diameter | 150 mm (6 inch) | 180 mm (7 inch) |
| Rated Current | 6.4 A | 12.5 A |
| Power Input | High Output Type | High Output Type |
| Safety Feature | Double Insulation | Double Insulation |
| Carbon Brush | KD-42 | KD-42 |
These grinders are specifically built for tasks that would overheat smaller tools:
Enhance your productivity with our compatible accessories:
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. |
Abrasive Selection Guide

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.
This product strictly complies with the Electrical Appliance and Material Safety Technology Standards (Noise Countermeasures), revised under the Ministry of Economy, Trade and Industry (METI) Ordinance No. 57.
*Official Enforcement Date: April 1, 2013. This ensures maximum electromagnetic compatibility (EMC) and operational stability in industrial environments.
Professional Note: For global industrial procurement, these Japanese METI standards ensure that Fuji tools meet high-level noise reduction requirements, critical for precision workshops across Europe and North America.
