Angle grinders require a high-temperature, extreme-pressure (EP) lithium soap grease with an NLGI #2 rating or a semi-fluid #00 grade grease. This formulation withstands intense friction, resists melting under high operating temperatures, and stays on the spinning gears rather than flinging off.Top RecommendationsLithium Complex Grease: The most common factory standard. Look for options like the Anglomoil Inplex 2163-220 or standard industrial lithium formulations.Moly Grease (Molybdenum Disulfide): Excellent for heavy-duty shock loading. A product like Penrite Molygrease EP 3% is a great choice for long-lasting gearbox protection.Semi-Fluid Grease: Often used in factory builds. If your grinder requires this specific consistency, semi-fluid corn head grease is a popular DIY
i dont think would need much @plasmo have you tried the motor to see if any play in shaft /whether its mounted properly? can get cheap low power ones that were industry standard 30 years ago. may just take a bit longer onsomethings. not for home stuff tho, less pwoer prob better.
