Benchmark Abrasives 4-1/2" x 7/8" Interleaf Flap Disc Type 29 (Angled Face)are made by combining coated abrasive flaps with our premium European non-woven surface conditioning material. By alternating flaps of coated material and non-woven material, we've made a flap disc that not only makes the grind/finish process faster but also produces a consistent finish. We offer them in three different grits/colors for sanding, blending, deburring, and cleaning. They are great for stainless steel, brass, aluminum, and much more. These discs are made with the highest quality non-woven, open nylon webbing, filled with premium abrasive grains (Equivalent to 3M™ Scotch-Brite™). These discs are perfect for cleaning, finishing, and deburring contoured or irregular surfaces.

These flap discs are Type 29 (angled face), perfect for grinding flat surfaces and outside edges. They are made with premium, Italian Bibielle surface conditioning material. These interleaf flap discs are designed by combining premium coated abrasive material with non-woven surface conditioning material.
