FAQs

Match the disc diameter to the guard fitted on your grinder and the backing pad you are running. Common sizes for trade use are 115 mm and 125 mm, though larger formats suit heavier fabrication work. The backing pad arbor thread must correspond to your grinder spindle, typically M14. If you are unsure whether a specific disc and pad combination will suit your machine, use Ask Simon on the relevant product page for an instant fitment check before ordering.

For paint, rust, and coating removal, choose a coarser conditioning or abrasive layer as it will cut through surface contamination quickly without excessive heat build-up. For weld blending and pre-prime finishing, move to a finer grade to control the surface profile and avoid undercutting parent metal. Running both grades on the same job is common practice: strip with the coarser, blend and finish with the finer before priming.

Poly discs are compatible with standard angle grinders provided the correct backing pad is fitted. The disc does not mount directly to the grinder spindle. A compatible polymer or rubber backing pad, listed in the same Poly Products section, is required to support the disc face and maintain concentricity. Check that the backing pad diameter matches the disc size and that the pad arbor fits your grinder spindle before use.

Listing formats and pack sizes vary by product. The individual product pages within the Poly Discs range show the unit and pack options available for each grade and diameter.

Flexible disc work covers a lot of ground in a fabrication or finishing bay: blending welds, removing surface coatings, preparing plate for painting, and knocking back high spots without the aggressive bite of a conventional grinding disc. Poly discs sit in that intermediate zone, pairing a polymer-backed carrier with an abrasive or conditioning surface to give the operator control over cut rate and finish.

PartsForMachines lists poly discs under the Poly Products range within the Cut and Grind section, where they are held as part of a curated set of abrasive and surface-conditioning accessories. Selection comes down to disc diameter (matched to the guard and backing pad on the angle grinder being used), the abrasive grade or conditioning layer, and the arbor fitting. Grade choice follows the surface and the task: coarser configurations for paint and rust removal, finer grades for blend-finishing or pre-prime preparation. Across this section, Abracs supplies the poly discs. Packs of 10 are the standard supply unit.

Poly discs wear differently from fibre discs and bonded grinding wheels. They are designed to be used through their full face rather than replaced at first glazing. Trade buyers running a high throughput of finishing work typically keep a mix of grades to hand, moving through the sequence rather than reaching for filler at the first surface irregularity. Backing pads and the relevant fixings are listed alongside in the same section, so the complete working assembly can be sourced in one place.

For confirmation on fitting or grade suitability before ordering, use Ask Simon on the relevant product page for an instant fitment check, or contact the team via WhatsApp 07754288583 or [email protected].
