- Model Compatibility — AGH230 / G18SE2 / FF1180A (Makita Type): This coil is precisely matched to the internal dimensions and electrical specifications of Makita-type 9-inch angle grinders bearing these model codes, ensuring a direct drop-in replacement with no modification required.
- DC Type Electrical Configuration: Designed specifically for DC-powered angle grinder circuits, the coil's winding count, wire gauge, and impedance characteristics are optimised for direct current input — delivering consistent torque and speed under load without voltage fluctuation issues common in mismatched coils.
- High-Grade Copper Wire Windings: The coil uses multi-strand, high-purity copper wire wound to tight tolerances, ensuring low resistance, superior current flow, and minimal heat generation — all critical factors for sustained performance during cutting, grinding, and surface-preparation tasks.
- High-Temperature Resistant Insulation & Magnetic Core: Wrapped in Class F or equivalent insulation material rated for elevated operating temperatures, the coil withstands the intense heat generated during prolonged use. The laminated magnetic core reduces eddy current losses, improving overall energy conversion efficiency.
- HQ Series Manufacturing Standard: Built to Ideal Power Tools' HQ (High Quality) Series specification, this coil undergoes stringent quality checks covering winding uniformity, insulation integrity, and dimensional accuracy — ensuring each unit meets the performance demands of professional-grade power tool repair.
- Cost-Effective Repair vs. Full Tool Replacement: A failed or burnt coil is one of the most common causes of angle grinder power loss. This OEM-compatible replacement coil (SKU: 30376) allows technicians to restore a tool to full operational condition at a fraction of the cost of purchasing a new machine — making it an essential spare for any tool service inventory.
This product is supplied as a bare field coil replacement component intended for installation by a qualified technician or experienced operator. It is compatible with Makita-type 9" DC angle grinder housings and is part of the Ideal Power Tools HQ Series spare parts range, which is designed to meet professional workshop and trade service standards.
General Purchase & Comparison Queries
Is this coil an OEM part or an aftermarket replacement?
This is an aftermarket replacement coil manufactured under the Ideal Power Tools HQ Series standard. It is engineered to be dimensionally and electrically compatible with Makita-type angle grinders (models AGH230, G18SE2, FF1180A) and is built to meet professional workshop performance requirements. While not an OEM Makita part, the HQ Series designation reflects stringent quality control covering winding uniformity, insulation integrity, and dimensional accuracy.
Which angle grinder models is this coil compatible with?
This coil is compatible with Makita-type 9" DC angle grinders matching the following model codes: ID AGH230, G18SE2, and FF1180A. The "Makita Type" designation means it is designed to fit the housing dimensions, shaft configuration, and electrical specifications of these Makita-platform machines. If you are unsure whether your grinder matches, compare your existing coil's dimensions and DC voltage rating before ordering.
Is it more cost-effective to replace the coil or buy a new angle grinder?
In most cases, replacing the field coil is significantly more cost-effective than purchasing a new machine. A burnt or failed coil is one of the most common causes of angle grinder power failure, and this HQ Series replacement (SKU: 30376) restores the tool to full working condition at a fraction of the cost of a new grinder. For workshop managers and contractors running Makita-type tool fleets, stocking replacement coils as spare parts is a proven maintenance strategy.
Product-Specific and Usage Queries
What does the DC type designation mean for this coil?
DC type refers to the coil being wound and insulated specifically for direct current (DC) powered angle grinder circuits. The winding count, wire gauge, and impedance are calibrated for DC voltage profiles — ensuring consistent torque, stable speed under load, and correct electromagnetic field generation. Using an AC-type coil in a DC grinder (or vice versa) can result in overheating, poor performance, or premature failure, so it is important to match the coil type to your tool's power system.
Can I install this coil myself, or do I need a technician?
This coil is supplied as a bare replacement component intended for installation by a qualified technician or experienced power tool repair operator. The installation process involves disassembling the grinder housing, removing the old coil, and correctly seating and wiring the new one. Improper installation can damage the tool or create safety hazards. If you are not experienced with power tool servicing, we recommend having the coil fitted by a professional workshop or service centre.
How does the high-temperature insulation benefit performance?
Angle grinders generate significant heat during prolonged cutting or grinding operations. The high-temperature resistant insulation on this coil — rated to Class F or equivalent standards — prevents the copper windings from short-circuiting or degrading under thermal stress. Combined with the laminated magnetic core that reduces eddy current losses, the coil maintains efficient energy conversion and structural integrity even during extended heavy-duty use, extending the service life of the repaired tool.
Problem/Solution-Oriented Queries
My 9" angle grinder has lost power or stopped working — could the coil be the issue?
Yes — a failed or burnt field coil is one of the most frequent causes of complete power loss or severe performance degradation in angle grinders. Common symptoms include the grinder not starting, producing a burning smell, generating excessive heat near the motor housing, or running intermittently. If your tool is a Makita-type 9" DC grinder (AGH230, G18SE2, or FF1180A), this HQ Series coil (SKU: 30376) is the correct replacement to restore full operation. Have the tool inspected by a technician to confirm the coil is the faulty component before ordering.
What happens if I use the wrong coil type in my angle grinder?
Installing an incompatible coil — whether the wrong model fit, wrong DC/AC type, or incorrect impedance — can cause a range of problems: overheating, reduced tool speed, erratic operation, or immediate burnout of the new coil. In severe cases, it can damage other motor components such as the armature or brushes, turning a simple repair into a costly rebuild. Always verify that the coil's model compatibility, DC/AC type, and physical dimensions match your specific grinder before installation.
How can I tell when my angle grinder's coil needs replacing?
Key signs that your field coil may need replacement include: the grinder failing to start despite a functioning power supply; a noticeable burning smell or visible scorching on the motor windings; the tool running at significantly reduced speed or power under normal load; intermittent cutting out during use; or a continuity test with a multimeter showing an open circuit or abnormally high resistance in the coil windings. If you observe any of these symptoms in a Makita-type 9" DC grinder, this HQ Series coil (SKU: 30376) is the recommended replacement part.
