  • 2-wire armature design for straightforward installation and reliable electrical connection
  • Precision-wound magnetic core and commutator for efficient energy transfer
  • CE Machine Test certified — meets European safety and performance standards
  • Engineered for high-impact, heavy-duty demolition applications with extended service life
  • Repairing Hitachi-type demolition hammers that have lost power or stopped running
  • Workshop technicians and power tool repair professionals
  • Construction and demolition contractors needing fast, reliable tool restoration
  • Preventive maintenance programs for high-use demolition equipment
  • OEM-Compatible Direct Replacement: Engineered specifically for the Hitachi ID PH65M and ID PH65HD demolition hammer models, this armature slots in as a precise drop-in replacement — no modifications required. The exact dimensional tolerances ensure a secure fit within the motor housing, eliminating vibration and misalignment that can cause premature wear.
  • 2-Wire Electrical Configuration: The 2-wire armature design simplifies the replacement process, reducing the risk of wiring errors during installation. The wire leads are pre-positioned for compatibility with the original brush and field coil assembly, ensuring correct polarity and a clean, secure connection from the first use.
  • High-Efficiency Magnetic Core and Commutator: The armature's precision-laminated magnetic core minimises eddy current losses, while the machined copper commutator segments maintain consistent brush contact under the high-RPM, high-torque demands of demolition work. This translates directly into stronger hammer blows and sustained performance over long operating cycles.
  • CE Machine Test Certified for Safety and Compliance: This armature carries CE certification verified through machine testing, confirming it meets the essential health, safety, and environmental protection requirements of the European Machinery Directive. It is supplied as a single armature unit (1 piece), ready for immediate installation, and is compliant for use in professional and commercial tool repair environments.
  • Built for Heavy-Duty Demolition Demands: Constructed with heat-resistant winding insulation and robust commutator materials, this armature is rated to withstand the continuous thermal and mechanical stress generated during intensive concrete breaking, chiselling, and demolition tasks. It restores the tool's rated output power, ensuring your demolition hammer performs at full capacity after every repair.
  • Cost-Effective Alternative to Full Tool Replacement: Replacing a worn or burnt-out armature is a fraction of the cost of purchasing a new demolition hammer. This high-quality spare part extends the operational life of your existing Hitachi-type tool, making it the smart, economical choice for contractors and repair shops managing fleet maintenance budgets.

General Purchase & Comparison Queries

Which demolition hammer models is this armature compatible with?

This armature is specifically designed for Hitachi-type demolition hammers, with confirmed compatibility for the ID PH65M and ID PH65HD models. The part number is 28761. If you are unsure whether this armature fits your specific tool, we recommend checking your hammer's model plate or contacting us with your model number before purchasing.

Is this an OEM part or an aftermarket replacement?

This is a high-quality aftermarket replacement armature engineered to OEM-equivalent specifications for Hitachi-type demolition hammers. It is manufactured to match the original dimensional and electrical tolerances of the factory part, and carries CE Machine Test certification, confirming it meets the required safety and performance standards for professional use.

Is it more cost-effective to replace the armature or buy a new demolition hammer?

In most cases, replacing the armature is significantly more cost-effective than purchasing a new demolition hammer. The armature is one of the most common wear components in a demolition hammer motor, and a quality replacement restores the tool to its full rated output. For contractors and repair shops managing multiple tools, armature replacement is the standard, economical approach to extending tool service life and reducing capital expenditure.

Product-Specific and Usage Queries

What does the 2-wire configuration mean and why does it matter?

The 2-wire armature configuration refers to the number of lead wires connecting the armature to the tool's electrical circuit. A 2-wire design is straightforward to install and reduces the risk of wiring errors during replacement. The leads are pre-positioned to align with the original brush and field coil assembly of the ID PH65M and ID PH65HD, ensuring correct polarity and a reliable electrical connection without the need for additional modifications.

What is included in the package and what certifications does this part carry?

Each order includes one armature unit (1 piece), supplied ready for installation. The armature is CE certified through machine testing, confirming compliance with European safety and performance directives applicable to power tool components used in professional and commercial repair environments.

Can this armature be installed without specialist tools?

Armature replacement on a demolition hammer is a technical repair task that requires disassembly of the motor housing. While experienced technicians and power tool repair professionals can complete the replacement with standard workshop tools, we recommend that those unfamiliar with power tool motor repair consult a qualified technician. Correct installation ensures the armature seats properly within the field coil and that the commutator aligns accurately with the carbon brushes for optimal performance.

Problem/Solution-Oriented Queries

My demolition hammer has lost power or stopped working — could the armature be the cause?

Yes — a faulty or burnt-out armature is one of the most common causes of power loss or complete failure in demolition hammers. Signs of armature failure include the tool running weakly, producing excessive sparking at the brushes, emitting a burning smell, or not starting at all. If your Hitachi-type ID PH65M or ID PH65HD is exhibiting these symptoms, inspecting and replacing the armature is the recommended first diagnostic step before considering more extensive repairs.

Will a worn armature damage other components in my demolition hammer?

Yes — continuing to operate a demolition hammer with a worn or damaged armature can cause secondary damage to the carbon brushes, field coil, and commutator. A deteriorating commutator surface accelerates brush wear, while electrical faults in the winding can overheat and damage the field coil insulation. Prompt armature replacement minimises the risk of cascading component failure and keeps the overall repair cost low.

How do I know if I have received the correct armature for my tool?

Before installation, verify the armature against your tool's original part by checking the shaft diameter, overall length, commutator diameter, and wire lead configuration. The correct armature for the ID PH65M and ID PH65HD carries part reference 28761 and features a 2-wire lead arrangement. If the physical dimensions do not match your original part, do not attempt installation — contact us with your tool's model and serial number and we will confirm compatibility.
