MIRKA 3" X 4" 33-HOLES H&L BACKING PAD (934GV)

The Mirka 3" × 4" 33-Hole Hook & Loop Backing Pad (934GV) is a replacement backing pad for Mirka orbital sanders.

It is used to:

  • Attach 3" × 4" Hook & Loop (H&L/Velcro®) sanding sheets.
  • Provide support for the sanding sheet while sanding.
  • Allow dust extraction through the 33-hole pattern, which aligns with Mirka's dust-free sanding system when connected to a vacuum.

It is commonly used with Mirka sanders such as:

  • Mirka DEOS 343CV (3" × 4" electric orbital sander)

The backing pad is not used by itself—it mounts onto the sander, and the sanding sheet attaches to the pad.

Typical setup:

  1. Mirka sander
  2. 934GV 3" × 4" 33-hole backing pad
  3. (Optional) Interface pad for contour sanding
  4. 3" × 4" Hook & Loop sanding sheet
  5. Dust extractor/vacuum connected to the sander

Aurora ★★★★★

My old pad was losing its grip, but this one's hook-and-loop surface grabs the 3x4 sheets firmly even on curved edges. It fits the sander perfectly and the 33-hole pattern keeps dust collection working like new.

Nicholas ★★★★★

The hook-and-loop grip holds my 3" x 4" paper firmly even after hours of sanding, and the 33-hole pattern keeps dust moving so the pad doesn't clog up. Swapping discs takes seconds, which saves me a lot of frustration on a big project.

Stella Q. ★★★★★

I've been using this backing pad for a few weeks now, and the hook-and-loop grip holds the paper firmly even during detailed contour sanding. It's noticeably thinner than my old pad, which gives me much better control on tight curves.
