Holders

Abrasive holders and backing accessories provide the connection between abrasive products and compatible power tools, helping aircraft maintenance technicians use cut-off wheels, Roloc discs, and radial bristle discs effectively. BAC offers abrasive holders and mandrels for several common 3M aerospace abrasive systems, including cut-off wheels, Roloc discs, and radial bristle discs.

Choosing the correct holder is important for proper fit, secure attachment, tool compatibility, and efficient abrasive performance. Always verify the abrasive size, attachment style, thread or shank configuration, and tool requirements before use.

Abrasive Holders for Aircraft Maintenance

Abrasive holders are designed to support different types of abrasive products used for cutting, sanding, surface conditioning, cleaning, and material removal. The appropriate holder depends on the abrasive being used and the power tool or grinder it will be attached to.

Roloc Disc Backing Pads

3M Roloc Disc Backing Pads are designed for use with compatible 2" and 3" Roloc abrasive discs. The Roloc attachment system allows technicians to change abrasive discs quickly when moving between different grades or applications.

Roloc backing pads can be used with abrasive products such as Roloc sanding discs, Scotch-Brite Roloc discs, and Roloc bristle discs. This makes the system useful for multi-step surface preparation and finishing work.

Cut-Off Wheel Holders

The Cut-Off Wheel Holder is designed to provide a mounting solution for compatible 3M cut-off wheels. Its 2-in-1 design accommodates cut-off wheels with either 1/4" or 3/8" center holes and features a 1/4" shank for use with compatible die grinders and pneumatic tools.

Use the holder only with abrasive wheels and tools that are compatible with the manufacturer's specifications. Verify the wheel diameter, arbor configuration, tool speed, and maximum rated RPM before operation.

Radial Bristle Disc Mandrels

Radial bristle discs require a compatible mandrel for attachment to a straight grinder or right-angle grinder. BAC offers the 3M 990 Unitized Wheel Mandrel for use with compatible 2" and 3" radial discs.

These systems are particularly useful for controlled removal of sealants, adhesives, coatings, and other surface residues. The appropriate mandrel and operating configuration should always be selected according to the abrasive manufacturer's instructions.

Selecting the Right Abrasive Holder

When selecting an abrasive holder, match the holder to both the abrasive and the tool. Check the following before ordering or installing an abrasive accessory:

• Abrasive type: Confirm whether you are using a cut-off wheel, Roloc disc, radial bristle disc, or another abrasive.
• Size: Match the holder to the abrasive diameter and configuration.
• Attachment: Verify the required thread, arbor, shank, or quick-change connection.
• Tool compatibility: Confirm that the holder is appropriate for the grinder, die grinder, or other power tool being used.
• Operating speed: Never exceed the maximum RPM or other operating limits specified by the abrasive or holder manufacturer.

Abrasive Accessories for MRO and Aircraft Maintenance

Abrasive holders are small components, but using the correct holder can make abrasive work more efficient and repeatable. Whether changing Roloc discs between surface-preparation steps, mounting a cut-off wheel to a compatible pneumatic tool, or attaching radial bristle discs for controlled residue removal, the correct holder helps provide a secure connection between the abrasive and the tool.

Browse BAC's selection of aircraft abrasives to find compatible sanding discs, Roloc discs, bristle discs, cut-off wheels, hand pads, and other surface-preparation products for aviation maintenance and MRO applications.
