BRUIN Backer Pad – 4 in., Flexible
BRUIN Backer Pad – 4 in., Flexible
The BRUIN Backer Pad is a 4 in. flexible backer pad, used to carry 4 in. polishing discs on a grinder or polisher.
Flexible is the third rung of a four-pad stiffness ladder that runs aluminum, rigid, flexible and super flexible. The body gives under hand pressure, so the disc follows a gentle curve – an eased edge, a bullnose, a shallow radius – instead of contacting only at one point. The attachment on this pad is not published: neither thread size nor face type is stated in any source we hold, so check it against your machine and your discs before ordering.
Key Features
- Flexible body – bends enough to keep the disc in contact around a curve
- 4 in. pad, sized for 4 in. discs
- Third of four stiffness grades in this line; stiffer than the super flexible pad, softer than the rigid and aluminum pads
- Attachment thread and face type are not published for this pad and are not stated here
What's Included
- 1 x 4 in. backer pad
Who Is This For?
Fabricators polishing shaped edges – eased, bullnose and shallow radius work – who need the disc to follow the profile. It is the wrong pad for large flat surfaces, where a flexible body lets the disc tip and round over the edge; use the BRUIN Backer Pad – 4 in., Rigid or the Aluminum Body pad for flat work. For deep contours and tight inside radii, step up in softness to the Super Flexible pad.
Frequently Asked Questions
What does a flexible backer pad do that a rigid one cannot?
A flexible backer pad bends under hand pressure, so the polishing disc stays in contact all the way round a curved edge instead of touching at a single point.
Will a flexible pad work on flat tops?
It can be used, but it is not the best choice: a flexible body allows the disc to tip, which rounds the arris on a flat surface. A rigid or aluminum-bodied pad holds the disc flat.
What size discs does a 4 in. backer pad take?
A 4 in. backer pad is sized for 4 in. polishing discs.
How many stiffness grades are offered?
Four in this 4 in. line: aluminum, rigid, flexible and super flexible.
