Product Description

4.5" Rubber Resin Fiber Backing Pad with 5/8"-11 Locking Nut Included (Premium Quality)

These 4-1/2” x 5/8”-11 Smooth Face Resin Fiber Disc Pads are ideal for general purpose grinding applications, especially with resin fiber discs that have a grit of 36 grit or higher. These fibre disc backup pads feature a flat face made of a flexible rubber compound. These rubber compounds allow for the retention of consistent properties over a wide range of temperatures and provide some flex while grinding. The backing pads are compatible with 4.5 inch resin fiber discs that have 7/8” arbors and are designed to be attached to 4-1/2” angle grinders. These backing pads, like all Kasco abrasive back up pads are proudly MADE IN THE USA and come with a screw on locking nut.

4.5 Inch Backing Disc

Listed as rubber, but is a black plastic. Tried it on grinder not equipped with any backing disc and it worked great, stiffer disc made the abrasive disc cut better (than other grinder with thick rubber disc). Had to drill the 2 small holes, larger on the retainer nut to work with wrench that came with the grinder.

Nice and Stiff, But Flexible Enough.

Works great. Excellent quality. Bends and deflects when I put pressure into it. Nice and flat under normal pressure.

Backing pad

I have had one of these for about a year and use it quite often. They work well for dressing welds off, removing tacks, and removing paint. I bought another because mine is showing some wear after lots of use. I would recommend them and if my memory serves me right they’re made in USA which is nice.

I was actually hoping to use this on my high speed pneumatic grinder. But it’s way to thick to fit the arbor on the tool but it work well on my angle grinder! The Zirconia disk work great though much more life out of the disks over other brands! The disk backer pad thickness for the high speed grinder is around.062-.0935 and is made out of a flexible tough material that are the same diameter as the disk that is being used. In my case I use 41/2” diameter disk with a 7/8 arbor hole to mount on the grinder! These types of backer pads are pretty much impossible for me to find, I have been looking for a long time to find them! These thin backer pads have got to be out there somewhere because Ingersol- Rand makes a high grinder but they make no mention of the backer pad parts, go figure! You folks may want to carry these pads for sale to help customers out!

Great service and communication with customers I will definitely be purchasing more products from you in the future! But please the thin backer discs for the high speed grinders!

Very well made backing pad

I am very impressed with this backing pad. In the past I've only been able to get cheap ones which break easily. This is awesome ! Plus MADE IN USA BABY !
