3M Disc Pad Face Plate Ribbed 81729, 9 in Hard Black, Case of 10

• Designed for use with a 3M Disc Pad Hub
• Plate accommodates a fiber disc of equal diameter
• Plate color indicates disc density for easy identification in the workroom
• Various flexibilities support grinding applications ranging from lightweight to heavy-duty

3M Disc Pad Face Plate backs a same size fiber disc (sold separately) to provide firm support and the force required for grinding applications. It is used in conjunction with a disc pad hub (sold separately), which attaches to the power tool, and held into place along with the appropriate disc using a retainer nut (sold separately).

This assembly allows 3M Disc Pad Face Plate to be easily changed without removing the disc pad hub, allowing the operator to use a single tool for multiple applications from heavy grinding to finishing a workpiece.

Some face plates have ribbing on the bottom face. Ribbed face plates provide additional force when needed for optimal fracturing of the abrasive mineral. By reducing the area of contact, or pressure per square foot (PSI), ribbed face plates increase the grinding pressure of the abrasive with the same amount of operator effort, and extend disc life when dulling is a problem.

Choose a plate with the level of firmness needed for the application—a lighter density face plate for lighter weight grinding applications, and a harder density face plate for more heavyweight grinding applications. Using the correct face plate for the application ensures that the abrasive mineral will fracture as it should, maximizing the life of the abrasive. The plate comes in one of four different colors that indicate the density so the correct plate can be easily identified in the workroom: red = extra hard (for heavy grinding with the coarsest grades), black = hard (for heavy metal removal, large welds, etc.), gray = medium (for general purpose grinding and finishing), and white = soft (for finishing operations on flat or contoured surfaces).

Trusted 3M Brand Model

The 3M Disc Pad Face Plate Ribbed 81729 is a reliable choice for grinding tasks. This model is designed specifically to work with a 3M Disc Pad Hub, ensuring compatibility and performance you can count on.

Using this exact model helps maintain consistency in your workflow. The ribbed design adds extra force for better abrasive fracturing, making it ideal for demanding applications.

Hard Black Disc Pad

This face plate comes in a hard black color, which indicates its density level. The hard density is perfect for heavy metal removal and large weld grinding, providing the firmness needed for tough jobs.

Choosing the hard black plate ensures the abrasive mineral fractures correctly, extending disc life and improving grinding efficiency on heavy-duty surfaces.

Generous Nine Inch Size

The 3M Disc Pad Face Plate measures 9 inches in diameter, matching the size of the fiber discs it supports. This size is common for many grinding applications, offering good surface coverage.

Its size allows for firm support of the fiber disc, which is sold separately. This ensures the grinding force is evenly distributed for consistent results.

Convenient Case Pack

This product is sold as a case of 10 face plates, making it easy to stock up for multiple projects or busy work environments. Buying in bulk helps reduce downtime by having spares ready.

Having a case of 10 also supports efficient tool changes, as the face plates can be swapped quickly without removing the disc pad hub, saving time during work.

Ribbed Plate Grinding Support

The ribbed bottom face of this plate increases grinding pressure by reducing contact area. This design helps the abrasive mineral fracture optimally, improving grinding performance with less effort.

Ribbing also extends the life of the disc when dulling occurs, making it a practical choice for heavy grinding tasks that require sustained pressure and durability.
