WEHA Backup Pad – 3.5 in., 5/8-11 Thread, for Weha Turbo Polishing Discs, Rigid
The WEHA Backup Pad is a 3.5 in. rigid backup pad with a 5/8-11 thread and a strong hook-and-loop face, made specifically to carry Weha's turbo polishing discs. An interior ridge in the face keeps the disc from shifting under load, which is what a rigid disc needs and a general backer does not provide.
This pad and the WEHA 3.5 in. Turbo Polishing Discs are a matched pair. The discs are rigid and have no thread of their own, so they cannot be mounted on a polisher without this backup pad — ordering discs alone leaves a buyer with nothing they can run.
Key Features
- 3.5 in. diameter, sized to the WEHA 3.5 in. Turbo Polishing Discs
- 5/8-11 thread
- Rigid body
- Strong hook and loop face
- Interior ridge that stops the disc shifting during use
Who Is This For?
Fabricators running the WEHA Turbo Polishing Discs for edge and flat work. Anyone buying those discs needs this pad; anyone who already has it only needs to reorder discs as grits wear out. For 5 in. surface pads on a flat top, the 5 in. rigid aluminum backup pad (WEH 51079) is the corresponding holder.
Frequently Asked Questions
What does this backup pad fit?
It is Weha's 3.5 in. backup pad for the Weha turbo polishing discs, with a 5/8-11 thread and a strong hook-and-loop face.
Can the turbo discs be used without it?
No. The WEHA 3.5 in. Turbo Polishing Discs are rigid discs with no thread of their own; they mount on this backup pad.
What is the interior ridge for?
The ridge inside the face of the pad stops the disc from shifting sideways under load, keeping it centered while it cuts.
What thread does it have?
5/8-11, which is the standard spindle thread on a stone polisher and grinder.
Will it hold 4 in. or 5 in. pads?
It is a 3.5 in. pad. A larger pad would overhang the backer, so use a backer sized to the abrasive — for example the 5 in. WEHA backup pad for 5 in. pads.
