61680, 3M Backing Pad, 115mm Diameter

3M™ Centre Pin Back-Up Pad

3M Centre-pin back up pads are used with Scotch-Brite surface conditioning discs. Used to prepare and/or finish metal surfaces in fewer steps and in less time than conventional abrasives, such as grinding discs and wire wheels. The centre-pin attachment system contributes to a reduction in tool vibration by centring, securing and maintaining the disc in the correct position on the back-up pad.

Features and Benefits

• Quick and easy placement and centering of discs
• Does not interfere with work surface
• Allows disc to be used at usual angle

What safety requirements should I observe?

When grinding metal or sanding, appropriate personal protection equipment should be worn. Gloves, eye protection and even respiratory protection are essential PPE for general purpose grinding and polishing applications.

For safe operation of an angle grinder, be sure you have participated in appropriate training and are aware of all safety advice relevant to the material you are working on.

Do I always need a backing pad when I use abrasive discs?

Using a backing pad is a simple way to improve the performance and extend the lifespan of abrasive discs in sanding jobs. If your pad is worn, it can damage the disc by wearing out the edges while leaving the middle relatively unused. Soft backing pads are suitable for fine surfaces where avoiding edge gouging is critical. Firm backing pads are ideal for coarse surfaces that need more pressure.
