We carry several other brands of flap discs, but we prefer these from Walter Surface Technologies.
We like how the Enduro-Flex flap discs feature trimmable backings made with ECO-TRIM wood fiber backing
material. 
When the flaps wear down to the outer diameter of the backing, trim away 1/4” of the backing at a time
(up to three times total). This Exposes fresh abrasive grain, extending disc life and giving you a fresh new cutting edge.
See the video here for a demonstration.
  • ENDURO-FLEX 2-in-1™

    ENDURO-FLEX 2-in-1™

    ENDURO-FLEX 2-in-1™ flap discs remove TIG welds and finish the surface in just one step. Save time and reduce your inventory by using just one disc instead of two or more to perform the same job.

     

  • ENDURO-FLEX 2-in-1™ Turbo

    ENDURO-FLEX 2-in-1™ The new Enduro-Flex™ 2-in-1 TURBO removes material faster and gets you the finish you want. These flap discs work on stainless steel and aluminum. Available in both 4.5” and 5”.

  • ENDURO-FLEX Alu™

    Enduro-Flex Alu™

    The new Enduro-Flex ALU™ uses a superior zirconia alumina grain blend that is free of iron, sulfur and chlorine. Thanks to its high removal rates, and resistance to glaze buildup, Enduro-Flex ALU™ is the optimal choice for operators looking to enhance both quality and productivity when working with aluminum or other heat sensitive metals.

     

  • ENDURO-FLEX Stainless™

    ENDURO-FLEX Stainless™ ENDURO-FLEX Stainless™ flap discs work on stainless steel, aluminum or any copper alloy. Made from natural and sustainable plant fibers, the ECO-TRIM backing can easily be trimmed for higher productivity. Low vibration offers maximum operator safety and comfort as well.

  • ENDURO-FLEX Turbo™

    ENDURO-FLEX Turbo™ ENDURO-FLEX TURBO™ flap discs use a 36/60 ceramic grain blend that removes material quickly and leaves a paint ready finish. The patented Turbofan™ design minimizes heat transfer to the surface which increases the disc life. ENDURO-FLEX TURBO™ performs on both steel and stainless steel. Type 29 wheels have a a higher ergonomic angle of attack for heavy-duty applications like blending contours, edges and corners.

  • ENDURO-FLEX™

    ENDURO-FLEX™

    The ENDURO-FLEX™ one-step finishing discs possess ultra sharp and refined zirconium grain.  These finishing discs will stay sharper for a longer period of time while removing more material faster. In addition, a special top coat continuously cools and lubricates the disc for smooth, vibration-free grinding and sanding from start to finish. Moreover, there is no need to discard the disc when the flap overhang is worn down to the backing because the ENDURO-FLEX disc can be restored to like-new performance by reducing the diameter of the ECO-TRIM backing.
