WEHA Turbo Disc – 3.5 in., 800 Grit
The WEHA Turbo Polishing Disc is a rigid 3.5 in. diamond edge-polishing disc in 800 grit, the refining step before the final gloss grits. It is a rigid disc rather than a flexible pad, so it holds a flat edge flat instead of rolling over the arris.
The disc has no thread of its own and cannot be run on its own. It mounts on the WEHA 3.5 in. backup pad, MPN 51080, which has a 5/8-11 thread, a strong hook-and-loop face and an interior ridge that stops the disc shifting under load. A buyer who orders discs without that pad has nothing they can put on a machine. No Weha product page is indexed for this MPN. The 3.5 in. size is taken from the confirmed siblings and the grit is read from the MPN suffix against Weha's own naming pattern across four verified discs, so the grit is treated as inferred rather than manufacturer-confirmed.
Key Features
- 3.5 in. rigid diamond polishing disc, 800 grit
- Requires the WEHA 3.5 in. backup pad (WEH 51080, 5/8-11 thread) — sold separately

- Grit ladder stocked here: 50, 100, 200, 400, 800, 1500 and 3000
Who Is This For?
Fabricators polishing flat edges, bevels and seam faces who run the whole grit ladder on one backup pad. It is the wrong tool for a curved profile or a sink bowl, which need a flexible pad: the WEHA Trio 3 Step pad (WEH 13341) is the flexible option, but only its step 1 is stocked here, so on its own it will not take a bowl or a curved edge through to a finished polish. It is also the wrong tool for blending a scratch repair on a quartz surface, which is what the WEHA Donkey surface pads (WEH 134293) are for.
