The FUJI FAG-180B (7" Pneumatic Angle Grinder) represents the pinnacle of power-to-weight efficiency. Designed for heavy-duty industrial environments where electricity is scarce or hazardous, this tool combines a massive 820W power output with an incredibly light 2.2kg body.
Operating at 7,000 RPM, it delivers the raw torque needed for aggressive material removal while significantly reducing operator fatigue compared to heavy electric alternatives. It is the preferred choice for shipbuilding, bridge construction, and off-grid maintenance.
Why Choose the FAG-180B?
🪶 Revolutionary Lightweight (2.2kg) Weighing nearly half as much as a standard electric 7-inch grinder. This drastic weight reduction allows for effortless overhead work and extended operation times without muscle strain.
⚡ High-Torque 820W Motor Don't let the size fool you. The advanced air motor delivers consistent 820W output, powering through rust, concrete, and structural steel with ease.
🛡️ Intrinsic Safety Ideal for hazardous zones. Pneumatic power eliminates the risk of electrical sparks and short circuits, making it safe for use in ship hulls, chemical plants, and damp environments.
🌬️ Side Exhaust System The intelligent side exhaust directs cold air, noise, and debris away from the operator, ensuring clear visibility and a cleaner working environment.

Industrial Applications
The FAG-180B is built for environments where durability is non-negotiable:
Shipbuilding & Marine: Heavy rust removal and weld dressing in salt-air environments.
Structural Steel: Grinding bridge beams and construction machinery components.
Remote Construction: Operating in off-grid locations using portable air compressors.
Foundry: Surface preparation and defect removal on large castings.
Frequently Asked Questions
Q: Why choose an air grinder over an electric one?
A: Air grinders are lighter, run cooler, and are safer in hazardous environments. The FAG-180B weighs only 2.2kg, whereas a comparable electric 7" grinder often weighs over 4kg.
Q: Does it have a spindle lock?
A: Yes, the FAG-180B features a built-in spindle lock system, allowing for quick and easy wheel changes using just one wrench.
Q: Is it suitable for cutting?
A: Yes, with the appropriate 180mm (7") cutting disc and safety guard, it is excellent for cutting steel and concrete due to its high torque and 7,000 RPM speed.

Efficiency Focused: Relies on machine guarding and operational procedures.
1.RPM Compliance: Never exceed the maximum R.P.M. specified on the wheel. Using the sides of the wheels for grinding is strictly prohibited, as it compromises the structural integrity of the abrasive bond.
2.Mandatory Idling: Allow the tool to idle for one minute before beginning work. If a new wheel has been mounted, an idle run of three minutes is required to ensure dynamic stability.
3.Workpiece Stability: All materials must be securely fastened. Improperly secured workpieces can lead to vibration, wheel binding, and unsafe kickback forces.
4.Arbor Hole Integrity: Do not modify or enlarge the metal center of the arbor hole. A proper fit is critical; a mismatched arbor causes eccentric rotation and dangerous vibration levels.
5.PPE Requirements: Industrial-grade face and eye protection are mandatory at all times. Ensure all protective gear meets local safety compliance standards.
6.Guard Protection: Protection guards are designed to contain fragments in the unlikely event of a wheel failure. Never operate tools or machinery with guards removed.

Professional Export & Maintenance Insight
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.
🛡️ Electrical Appliance & Safety Compliance
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.
How to Read Operational & Safety Symbols
Key Safety Indicators:
Double Insulation: Marked by the "square-in-a-square" symbol, indicating no grounding is required for safe operation.
Noise Suppression: Compliance with Ordinance No. 57 prevents interference with other electronic equipment.
Mandatory PPE: Visual cues for hearing, eye, and respiratory protection.
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.
