- Electromagnetic Coil Assembly — GSH11E Specific: Engineered as a direct-fit replacement for the DeWalt GSH11E demolition hammer, this coil assembly slots into the stator housing without modification, restoring factory-rated electromagnetic field strength and ensuring the hammer returns to its rated impact performance immediately upon installation.
- Copper Wire Windings with Precision Gauge: The coil is wound with high-conductivity copper wire at a precisely controlled gauge and turn count, minimising resistive losses and ensuring consistent current draw. This directly translates to stable motor torque, reduced heat generation within the windings, and a longer operational lifespan under high-cycle demolition workloads.
- High-Temperature Resistant Insulation System: Each winding layer is coated with a thermally rated insulating varnish designed to maintain dielectric integrity even under sustained high-load operation. This prevents inter-winding short circuits — the most common cause of coil failure in demolition hammers used in demanding construction and breaking applications.
- Laminated Magnetic Core for Low Eddy Current Loss: The magnetic core is constructed from stacked laminated silicon steel sheets, a design that significantly reduces eddy current losses and core heating. The result is more efficient conversion of electrical energy into mechanical energy, lower running temperature, and better energy efficiency compared to solid-core alternatives.
- Part Number 30379 — Direct OEM Reference for the DeWalt GSH11E: This spare part is catalogued under Part No. 30379 and cross-references directly to the DeWalt GSH11E coil specification. It is sourced and supplied as part of the ID HQ Series, a range of premium-grade power tool spare parts designed to meet or exceed original equipment manufacturer standards in terms of material quality, dimensional accuracy, and electrical performance.
This coil spare part is supplied as a single replacement coil unit (Part No. 30379), ready for installation into compatible GSH11E demolition hammer housings. As part of the ID HQ Series range distributed by Ideal Power Tools, the product is held to the quality and safety standards applicable to power tool spare parts supplied within the UAE market, in line with MOIAT regulatory requirements for electrical components.
General Purchase & Comparison Queries
Is this coil an original OEM part or an aftermarket replacement?
This coil (Part No. 30379) is supplied as part of the ID HQ Series by Ideal Power Tools — a premium aftermarket spare parts range engineered to meet or exceed original equipment manufacturer (OEM) specifications. It is designed as a direct-fit replacement for the DeWalt GSH11E demolition hammer, matching the OEM coil in terms of winding gauge, core dimensions, and insulation rating, at a more competitive price point than factory-original parts.
Which demolition hammer models is this coil compatible with?
This coil is specifically engineered for the DeWalt GSH11E demolition hammer. It is referenced under the DeWalt Type classification, meaning it matches the stator housing dimensions, electrical specifications, and terminal configuration of the GSH11E series. If you are unsure whether your specific model variant is compatible, we recommend cross-referencing the part number 30379 against your tool's spare parts diagram before ordering.
Is it more cost-effective to replace the coil or buy a new demolition hammer?
In most cases, replacing a faulty coil is significantly more cost-effective than purchasing a new demolition hammer. The ID HQ Series Coil (Part No. 30379) restores full electromagnetic performance to your GSH11E at a fraction of the cost of a new unit. Provided the hammer's mechanical components — such as the piston, cylinder, and impact mechanism — remain in good condition, a coil replacement will return the tool to factory-rated output and extend its working life considerably.
Product-Specific and Usage Queries
How does the coil work inside a demolition hammer?
The coil — also referred to as the stator winding — is the stationary electrical component inside the demolition hammer's motor. When alternating current passes through the copper wire windings, it generates a rotating electromagnetic field that drives the motor's armature (rotor). This rotational energy is then converted by the hammer's internal mechanism into the powerful reciprocating impact action used for breaking concrete, masonry, and similar materials. A degraded or failed coil results in reduced motor power, overheating, or complete tool failure.
Can I install this coil myself, or does it require a professional technician?
Coil replacement in a demolition hammer requires disassembling the motor housing and working with electrical components. While an experienced DIY user familiar with power tool repair may be able to complete the installation, Ideal Power Tools strongly recommends that this replacement is carried out by a qualified power tool technician or authorised service centre. Improper installation can result in further damage to the tool, electrical hazards, or voiding of any remaining warranty. The coil (Part No. 30379) is supplied ready-to-install and does not require any modification.
What are the signs that the coil in my GSH11E needs to be replaced?
Common indicators of a failing or failed demolition hammer coil include: the tool losing power progressively during use; the motor producing a burning smell or visible smoke; the hammer failing to start despite the switch functioning correctly; or the motor running but the impact mechanism not engaging at full force. An electrical continuity test or resistance test performed with a multimeter across the coil terminals can confirm a fault. If the winding shows an open circuit or significantly abnormal resistance, replacing the coil with Part No. 30379 is the recommended course of action.
Problem/Solution-Oriented Queries
My GSH11E demolition hammer has lost power — could the coil be the cause?
Yes, a degraded or partially shorted stator coil is one of the most common causes of power loss in a demolition hammer. When the copper wire windings deteriorate due to heat, moisture, or mechanical stress, the electromagnetic field generated becomes weaker, directly reducing motor output and impact force. Before replacing the coil, it is advisable to also check the carbon brushes and armature for wear, as these components work in conjunction with the coil. If the coil is confirmed as the fault, replacing it with the ID HQ Series Coil (Part No. 30379) will restore the hammer to its rated performance.
The hammer overheats quickly during use — can a faulty coil cause this?
Yes. A coil with damaged or degraded insulation can develop inter-winding short circuits, which dramatically increase resistive heat generation within the motor. Similarly, a coil with broken or corroded windings draws irregular current, causing the motor to work harder and run hotter than normal. The ID HQ Series Coil (Part No. 30379) features a high-temperature resistant insulation system and a laminated magnetic core that minimises eddy current losses — both design choices that directly reduce operating temperature and protect the motor from thermal damage during sustained heavy-duty use.
I cannot find the original DeWalt coil part — is this a suitable substitute?
Yes. The ID HQ Series Coil (Part No. 30379) is catalogued as a DeWalt Type replacement, meaning it is dimensionally and electrically matched to the OEM coil specification for the GSH11E demolition hammer. It is designed as a direct substitute when the original DeWalt spare part is unavailable or when a more cost-effective repair solution is preferred. The coil is supplied by Ideal Power Tools as part of the ID HQ Series — a range committed to maintaining OEM-comparable quality standards for professional power tool maintenance and repair.
