Specifications

How It Works

Simply press the hook-and-loop side of the buffer disc onto your existing sander back-up pad. The soft sponge layer creates a cushioned interface between the hard pad and your sandpaper, allowing the disc to conform to curved and uneven surfaces while keeping the backing pad protected from wear. When the sponge disc wears out, peel it off and replace it — no tools required.

Frequently Asked Questions

Q: What sizes does this hook and loop sponge buffer disc come in?

A: The sponge buffer disc is available in six sizes: 2" (50mm), 3" (75mm), 4" (100mm), 5" (125mm), 6" (150mm), and 7" (180mm). Please allow a ±2mm tolerance on the outer diameter. Select the size that matches your existing sander back-up pad.

Q: Does this listing include the sander back-up pad?

A: No — this listing includes 1 × sponge buffer disc only. The back-up (backing) pad is sold separately. The buffer disc attaches to your existing back-up pad via the hook-and-loop fastening system.

Q: What is the purpose of the sponge buffer disc on an air sander?

A: The sponge buffer disc acts as a soft cushion layer between the rigid back-up pad and the sandpaper. It protects the back-up pad from direct wear during dry sanding, allows the disc to conform to uneven surfaces and curved areas, and helps extend the overall lifespan of your sander accessories.

Q: Is this buffer disc compatible with random orbital air sanders?

A: Yes. The hook-and-loop backing makes it compatible with most standard pneumatic (air) sanders and random orbital sanders that use hook-and-loop (Velcro-style) back-up pads in the corresponding size. Always confirm your back-up pad's diameter and attachment type before purchasing.
