Help buyers compare angle grinder flange sizes, verify grinder compatibility, and select the correct pressure plate specifications before purchasing or requesting OEM/ODM customization.
Choose the Correct Angle Grinder Flange Before Ordering
Selecting the right flange is critical for grinder safety, cutting performance, and compatibility. This guide provides verified flange dimensions, M10 and M14 thread references, grinder fitment guidance, and OEM/ODM sourcing support for distributors, wholesalers, Amazon sellers, and industrial buyers.

Quick Answer
The most common angle grinder flange systems are M10 and M14. Smaller grinders typically use M10 flanges, while many 115mm, 125mm, 180mm, and 230mm grinders commonly use M14 flanges. Buyers should verify thread size, outer diameter, inner hole dimensions, and pressure plate compatibility before placing an order.
If compatibility is uncertain, measuring the existing flange and comparing it with a verified size chart is the safest approach. For OEM and ODM projects, flange dimensions can also be customized according to drawings, samples, or technical requirements.

What Is an Angle Grinder Flange?
An angle grinder flange is a key component used to secure cutting discs, grinding wheels, and abrasive accessories onto the grinder spindle. A complete flange system typically consists of an upper pressure plate and a lower pressure plate working together to clamp the disc securely during operation.
The lower pressure plate provides stable support and positioning, while the upper pressure plate applies clamping force to keep the disc centered and secure. Correct flange dimensions are essential for safety, vibration control, and reliable power transmission.
Angle Grinder Flange Compatibility Chart
| Thread Type | Common Grinder Size | Typical Disc Bore | Common Applications |
|---|---|---|---|
| M10 | 100mm | 16mm | Light-duty cutting and polishing |
| M14 | 115mm-125mm | 22.23mm | General metalworking and fabrication |
| M14 | 180mm | 22.23mm | Heavy-duty grinding |
| M14 | 230mm | 22.23mm | Industrial cutting applications |
Actual compatibility may vary depending on grinder manufacturer and regional standards. Buyers should verify dimensions before ordering.
Typical Applications by Grinder Size
100mm Angle Grinders
Commonly used for light-duty cutting, polishing, and maintenance work. M10 flange systems are frequently found in this category.
125mm Angle Grinders
Often selected for general-purpose metal fabrication and construction applications. M14 flange systems are commonly used.
180mm Angle Grinders
Suitable for more demanding grinding and material removal tasks requiring greater stability and torque capacity.
230mm Angle Grinders
Frequently used in industrial environments for heavy cutting and large-scale construction projects.
