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.
Select Your Model
1. HD-150 (6-Inch / 150mm)
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.
Motor Current: 6.4 A
Wheel Size: 150 mm
Best For: Medium-heavy grinding, pipe cutting, and maintenance.
2. HD-180 (7-Inch / 180mm)
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.
Motor Current: 12.5A
Wheel Size: 180 mm
Best For: Heavy stock removal, smoothing large welds, foundry deburring.
Why Choose FUJI Heavy-Duty Series?
⚡ Powerful Torque Motors Equipped with 11A (HD-150) and 12.5A (HD-180) motors. These high-amp units provide the sustained torque needed to grind through cast iron and steel without stalling.
🛡️ Double Insulation Safety Designed with a double insulation structure that requires no grounding wire. This critical safety feature protects the operator from electric shock in harsh industrial environments.
🤲 Solid & Secure Grip The body is designed for a secure, two-handed grip (using the side handle), essential for controlling the high torque of a 7-inch grinder safely.

Heavy-Duty Applications
These grinders are specifically built for tasks that would overheat smaller tools:
Shipyards: Removing heavy rust, barnacles, and paint from hulls.
Foundries: Snagging and deburring large castings.
Structural Steel: Smoothing flame-cut edges and heavy weld seams.
Civil Engineering: Cutting concrete and stone (with appropriate guards and diamond blades).
Frequently Asked Questions
Q: When should I choose a 7-inch (180mm) grinder over a 4-inch (100mm) one?
A: Choose the 7-inch HD-180 when you need to remove large amounts of material quickly or cut deeper. The larger wheel surface area and higher torque motor make it far more efficient for heavy-duty jobs like smoothing large weld seams or foundry work.
Q: Does the machine come with a side handle?
A: Yes, both HD-150 and HD-180 include a heavy-duty side handle. Due to the high torque of these tools, using the side handle is mandatory for safe operation and control.
Q: Is grounding required for these tools?
A: No. These models feature a "Double Insulation" construction, which provides two layers of electrical insulation. This eliminates the need for a ground wire and enhances safety, especially in industrial environments.

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.

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.
