FUJI KOSOKU HD-180 180mm / 7-Inch 220V Angle Grinder

The FUJI KOSOKU HD-180 is a single-phase 220V export-model corded AC angle grinder for 180mm / 7-inch wheels, made in Japan for heavy-duty metal grinding and fabrication. It is designed for weld leveling, edge preparation and surface grinding with an abrasive matched to the workpiece.
FUJI KOSOKU HD-180 180mm 7-inch AC angle grinder

The HD-180 is the main model presented here. The HD-150 150mm / 6-inch angle grinder is a smaller-wheel option in the same series. Select each machine by its approved wheel size and electrical rating; do not fit a 180mm wheel to the HD-150.

FUJI KOSOKU HD-180 180mm 7-inch AC angle grinder

Why Choose the HD-180?

  • 180mm working format: suitable for accessible weld seams, edges and larger steel surfaces where a 7-inch tool fits the job.
  • Corded AC operation: match the supplied machine to the local voltage and frequency. This is not a 250Hz or 300Hz high-frequency grinder.
  • Double-insulated construction: follow the insulation marking and the supplied electrical instructions. Inspect the cable and tool regularly.
  • Two-handed control: use the prescribed side handle and guard, secure the workpiece and maintain a stable working position.

HD-180 and HD-150 at a Glance

Selection point HD-180 — main model HD-150 — alternative
Wheel diameter 180mm / 7-inch 150mm / 6-inch
Tool type Corded AC angle grinder Corded AC angle grinder
Typical selection Steel weld grinding, edge preparation and general fabrication with approved 180mm accessories Jobs requiring the 150mm wheel format
Electrical specification Confirm voltage, frequency, rated input and current for the supplied version before ordering.
Accessory fit Check the manual for maximum RPM, bore, flanges, wheel type, thickness and guard requirements.

Export configurations must be confirmed in the quotation. Do not assume that one machine accepts every voltage, or transfer a current or power figure from another voltage version.

HD-180 Voltage Versions and Handling

The HD-180 220V export version serves overseas workshops. The Japanese domestic HD-180 100V is a separate electrical version; these are not dual-voltage tools. The Japanese catalog also lists HD-182 at 200V, which should not be confused with the HD-180 220V export model. Confirm supply frequency, rated input, speed and plug on the supplied machine before ordering.

The catalog describes a lightweight, double-insulated design with a 429mm overall length and a 74mm head dimension. The side handle and compact body support controlled two-handed handling during weld dressing and surface work. Choose a tool that suits the operator and working position; actual fatigue depends on the task, duration and technique.

HD-150: the 150mm / 6-Inch Alternative

For work requiring a smaller wheel format, the HD-150 offers a 150mm alternative. The following figures apply to the Japanese 100V HD-150 catalog model, not the HD-180 220V.

Wheel dimensions 150 × 6 × 22mm
Rotation speed 8,000 min⁻¹
Voltage / current 100V / 11.0A
Power consumption 1,050W
Weight / cord 3.8kg / 2.5m
Spindle M16 (2.0) × 11.5mm
Carbon brush KD-42
Catalog accessories Wheel, spanner and side handle

Applications in Fabrication and Maintenance

  • Steel weld leveling: remove excess weld material within the fabrication specification, avoiding unnecessary removal of the base metal.
  • Edge preparation: deburr and dress accessible steel edges with a suitable grinding wheel.
  • Shipyard and workshop maintenance: select the abrasive for the surface and task, and control sparks and dust.
  • Casting cleanup: confirm the casting material and wheel suitability before evaluating grinding performance.

Match the HD-180 with the Right FUJI Wheel

For everyday steel grinding, consider the FUJI Super F2 180mm grinding wheel, an economical aluminium-oxide option for everyday ordinary-steel weld grinding, deburring and surface work. Pairing FUJI wheels with a FUJI grinder allows coordinated selection of the machine, abrasive and application for a practical balance of removal efficiency and handling. Verify mounting, maximum speed and approved grinding configuration.

For metal cutting, the Gold Raicho 180 × 2.6 × 22.23mm cutting disc balances cutting action and wear resistance. Use only if the HD-180 manual permits the cutting operation and the correct cutting guard and flanges are fitted. Never use a cut-off wheel for side grinding.

See the grinding wheel specifications guide for help reading abrasive markings.

Frequently Asked Questions

Is the HD-180 a high-frequency grinder?

No. The HD-180 is a corded AC angle grinder. Select a supply matching its nameplate; do not connect it to a high-frequency grinder power system.

Can I use the same wheel on the HD-150 and HD-180?

Do not assume interchangeability. The models have different wheel diameters. Follow the individual machine manual for diameter, speed, mounting and guard compatibility.

Will a 7-inch grinder always work faster than a smaller grinder?

No. Productivity depends on the material, weld geometry, abrasive, available access and operating technique. Compare accepted work completed, wheel consumption and operator handling under equivalent conditions.

Which electrical version should I order?

Provide your destination country, supply voltage and frequency. Ask FUJI to confirm the available machine version, plug, rated input, maximum speed and included accessories in the quotation.

KOSOKU Tool-Making Experience, FUJI Abrasive Expertise

FUJI's official company history records the development of Japan's first angle grinder in 1955. Kosoku Electric merged with FUJI in April 2012, as documented in FUJI's company newsletter. Combining power-tool and abrasive manufacturing experience helps customers select a suitable machine-and-wheel combination for the material and job.

Request an HD-180 Quotation

Send your material, grinding or cutting operation, current wheel specification, power supply and order quantity. Specify HD-180, 180mm / 7-inch for this model, or HD-150 if you require the 150mm alternative.

FUJI Industrial Quality & Safety Protocols

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.

⚠️ Essential Safety Cautions & Operational Integrity

  • 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.
