The FUJI HSI-670F is a high-performance straight grinder engineered for the toughest industrial environments. Unlike standard angle grinders, its straight, elongated design allows for precision inner grinding inside pipes, castings, and confined spaces where other tools cannot reach.
Delivering 7 Amps of power at 13,000 RPM, this tool is a powerhouse for rust removal, deburring, and buffing. Weighing 4.4kg, it offers a robust, stable platform that reduces vibration during heavy-duty operation, ensuring operator control and finish quality.

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.
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.
