Cloth Sanding Belts Unpunched 533 x 75mm 40 Grit 5 Pack (88502)

Hello johny56, That depends on what you're trying to achieve. Use something coarse (like this one) with a low grit for rapid removal of material, then work up to something finer with a high grit for finishing. If you just want to sand edges down to a smooth finish after cutting you can skip the coarse grits and start with something medium//fine to fine. Thanks for using Q&A, KC
