ID HQ SERIES ARMATURE [ID AGH230] [G18SE2] [FF1180A] [9"] [DC TYPE] ANGLE GRINDER SPARE PART [Makita Type] - 28777

This is an aftermarket replacement armature from Ideal Power Tools' HQ Series, engineered to OEM specifications for the Hitachi G18SE2, FF1180A, and ID AGH230 angle grinders. It is manufactured to match the original dimensions, winding configuration, and commutator tolerances, offering a cost-effective alternative to sourcing a direct Hitachi OEM part without compromising on fit or performance.

Replacing the armature is significantly more economical than purchasing a new grinder. The armature is one of the most common wear components in an angle grinder, and if the rest of the tool — the gearbox, housing, and guard — is in good condition, a replacement armature restores full performance at a fraction of the cost. This part is priced at AED 60, making it a practical choice for professional workshops managing tool maintenance budgets.

Yes. This armature carries a CE conformity certificate issued following machine testing, confirming it meets the relevant European safety and electromagnetic compatibility directives for power tool spare parts. It is suitable for use in professional repair workshops, industrial maintenance operations, and commercial tool servicing environments where compliance documentation is a requirement.

This armature is specifically designed for Hitachi-type 9" angle grinders, with confirmed compatibility for the following models: Hitachi G18SE2, FF1180A, and ID AGH230. The part reference is ID AGH230 / SKU 28777. If you are unsure whether your grinder model is compatible, we recommend cross-referencing your tool's model number or contacting us before purchasing.

DC type refers to the armature's winding configuration, which is designed to work with the direct-current characteristics of the tool's motor circuit. In angle grinders, the armature type must match the original motor design — using an incorrect type will result in poor performance, overheating, or failure to start. This armature is specifically wound as a DC type to match the original motor specification of the G18SE2, FF1180A, and AGH230 grinders, ensuring correct RPM, torque output, and thermal behaviour.

The package contains one (1) HQ Series DC Type Armature (SKU: 28777), ready for installation. No additional tools, brushes, or hardware are included. If you also require carbon brushes or other angle grinder spare parts for a complete service, these are available separately in our catalogue.

Excessive sparking and loss of power are two of the most common symptoms of a worn or damaged armature. Sparking typically occurs when the commutator surface is worn, pitted, or has developed open circuits between segments, causing the carbon brushes to arc. Power loss results from degraded winding insulation or shorted coils reducing the motor's electromagnetic efficiency. Replacing the armature with this HQ Series unit will restore the commutator contact surface and winding integrity, resolving both symptoms in most cases.

Yes, a burnt armature is a common cause of complete motor failure in angle grinders, particularly after prolonged heavy-duty use or if the tool was operated without adequate ventilation. Signs of a burnt armature include a burning smell, visible discolouration or melted insulation on the windings, and zero response when the trigger is pressed. Before replacing the armature, also inspect the carbon brushes and switch to rule out simpler causes. If the armature is confirmed as the fault, this ID HQ Series replacement (SKU 28777) is a direct-fit solution for the G18SE2, FF1180A, and AGH230.

Armature replacement on a 9" angle grinder is a moderate-level repair typically performed by trained technicians or experienced DIY users. The process involves disassembling the motor housing, removing the field coil assembly, extracting the old armature, and fitting the new unit before reassembly. Standard tools required include screwdrivers, snap-ring pliers, and a bearing puller if the bearings need to be transferred. We recommend this repair be carried out by a qualified power tool technician to ensure correct reassembly and safe operation.
