XS 561 Aluminium Oxide Flap Disc

Better

The XS 561 is a premium aluminium oxide flap disc on X-weight polycotton, for weld removal and blending on mild steel and stainless steel in light to medium duty fabrication. Close coat construction maximises grain coverage across each flap — the disc cuts consistently across its full working life without the bald patches that develop on lower-density coated alternatives as the flaps wear back.

Product Information

Features

- Premium aluminium oxide grain on X-weight polycotton backing with close coat

- Close coat provides high grain density across each flap — consistent cut as disc wears

- Available in Type 27 and Type 29, 4" to 7"

Benefits

- Consistent grain density across all flaps means cut rate holds from the outer diameter through to the worn flap — no drop in performance as the disc ages

- X-weight polycotton provides the correct stiffness-to-compliance balance for weld toe blending and surface conditioning on fabricated MS components

- Premium Aluminum Oxide grain delivers reliable material removal on light to medium duty MS and SS weld removal without the cost of ceramic or zirconia grades

Advantage

- Close coat construction is the reason XS 561 holds cut rate as flaps wear — lower density alternatives develop bald zones that force the operator to increase disc pressure
