FAQs

Match the disc diameter to your grinder's guard and spindle specification. The two dominant trade sizes are 115mm and 125mm. Using an undersized or oversized disc relative to the guard is a safety violation and will void manufacturer compliance. Check the grinder's nameplate or manual for the maximum disc diameter permitted, then select accordingly. Bore size must also match the spindle thread, typically M14 for most trade angle grinders. Never fit a disc rated for a lower maximum RPM than your machine's no-load speed.

The difference lies in the abrasive grain and bond formulation. Stone and masonry discs use silicon carbide or a grain suited to aggregate, brick, and concrete, which are harder and more brittle materials. Metal-grinding discs use bonded aluminium oxide, which cuts steel and cast iron without loading or glazing. Fitting a metal disc to masonry, or vice versa, produces poor results and accelerates disc wear. The disc face or packaging will carry a material suitability symbol, and the product listing on the site specifies compatible materials for each variant.

Abracs semi-flex grinding discs have a slightly flexible fibreglass-reinforced backing that allows a degree of contour-following during use. On weld seams, fillet joints, and curved surfaces, this flexibility keeps more of the abrasive face in contact with the workpiece compared with a fully rigid disc, which can bridge and cut unevenly. The 115mm x 16 grit variant is a coarse-cut option suited to weld preparation and aggressive stock removal. Standard rigid depressed-centre discs are better suited to flat surface work where backing flex is not required.

Trade quantity pricing is available on the listed grinding disc ranges. If the pack size shown on a product page does not match your workshop's requirement, contact the team directly via WhatsApp 07754288583 or email [email protected] to discuss volume options. Mixed orders combining 115mm and 125mm discs, or different grain specifications within the same range, can be discussed at the same time. Having your grinder models and approximate monthly usage to hand will help the team confirm the most practical pack configuration for your account.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Grinding Discs

Angle grinder discs take the direct punishment of cutting and grinding work: stone, concrete, masonry, metal, and weld seam removal all demand a disc matched to the material, the machine diameter, and the required finish. PartsForMachines lists grinding discs for the 115mm and 125mm angle grinders found across professional workshops and site work, operating as Authorised Distributor and Seller for the abrasive ranges carried on the site.

Selecting correctly means matching three attributes before anything else: disc diameter (115mm and 125mm being the two dominant trade sizes), bore size to suit the grinder's spindle, and grain specification. Stone and masonry discs carry a silicon carbide or aluminium oxide grain suited to aggregate and concrete; metal-grinding discs use bonded aluminium oxide for steel and cast iron. Abracs semi-flex grinding discs, including the 115mm x 16 grit variant searched by trade buyers, combine a slightly flexible backing with an aggressive open coat, making them a preferred choice for weld preparation and surface blending where a rigid disc would bridge.

Wear rate is the practical discipline here. A disc that suits a trade grinder running continuous passes will degrade faster than its rated diameter suggests if it is pushed into the material rather than allowed to cut. Pairing the correct disc specification with the grinder's RPM rating and guard configuration keeps consumable costs predictable and the finish consistent. Replacement discs sit alongside grinding cups, flap discs, and cutting discs within the same section for straightforward replenishment ordering.
