✅ Authentic 999044 / 999044A Series—specifically designed for heavy-duty Hitachi (now HiKOKI) motors to ensure stable electrical conductivity and minimize commutator wear.
✅ Dimensions: 7mm x 17mm x 17mm—precision-engineered to fit perfectly into the brush holders of high-wattage tools, preventing sticking or excessive arcing.
✅ High-Grade Electro-Graphite Material—offers the perfect balance of hardness and self-lubrication, extending the service life of your tool's armature even under continuous industrial use.
✅ Wide Model Compatibility—the primary carbon brush for many of Hitachi's most famous "workhorse" machines, including demolition hammers, routers, and chop saws.
✅ Auto-Stop Safety (Selected Versions)—some 999044 variants feature an auto-cut mechanism that stops the motor when the carbon is worn down, protecting the commutator from expensive damage.
✅ Easy Replacement—standard terminal cap design allows for a quick, "plug-and-play" swap without needing to disassemble the entire motor housing.
