FAQs

Match the disc diameter to your tool. Small angle grinders use 100mm or 115mm discs; large angle grinders use 180mm or 230mm; 125mm sits in between and fits both small and medium grinders. The arbor bore (the centre hole) must match the spindle on your tool — 22.23mm (7/8 inch) is the standard for angle-grinder discs across all common diameters. Disc diameter and arbor are listed on product pages; if in doubt, check the spindle size on your tool.

A cutting disc is thin (typically 1-3mm) and used edge-on to cut through metal, stone, or tile. A grinding disc is thicker (typically 6-7mm) and used flat-on to remove material, dress welds, or shape metal. A flap disc has overlapping abrasive flaps bonded to a backing plate — used for blending, light grinding, and finishing where a softer cut is needed. Match the disc to the job: cutting discs for cutting only, grinding discs for material removal, flap discs for finishing.

Standard bonded abrasive discs work for mild steel, structural steel, and general fabrication. Stainless steel needs a contamination-free disc (no iron, sulphur, or chlorine in the bond) — these are clearly marked. Stone and concrete cutting requires diamond blades; thin tile and porcelain need fine-segment diamond blades. Aluminium and non-ferrous metals work best with TCT-bladed circular saws rather than abrasive cut. Each product page lists the rated material.

No — bonded abrasive discs have a stamped expiry date (typically 3 years from manufacture) printed on the metal hub. Beyond that date, the bond can degrade and the disc may shatter under load. Operate within the expiry window, store discs flat in dry conditions away from moisture and chemicals, and never use a disc that shows cracks, chips, or moisture damage. Always check the maximum RPM stamped on the disc against your tool's spindle speed before use.

Cut & Grind

Within Cutting, Grinding, Sanding, and Polishing, Cut & Grind covers the cutting and grinding consumables used with angle grinders, cut-off saws, bench grinders, and similar power tools — the working edges that turn a power tool into a metal-cutting, stone-cutting, or material-removal tool. Within Cut & Grind you will find Abrasive Cutting & Grinding (the standard bonded abrasive discs), Diamond Blade (for stone, concrete, and tile cutting), Diamond Cores (for core-drilling masonry and concrete), Flap Discs Range (for blending, finishing, and light grinding), Poly Products (polyester-bonded abrasives for stainless and finishing applications), and TCT Blades Range (tungsten-carbide-tipped circular saw blades for wood, metal, and composite cutting). Parts For Machines is an Authorised Distributor and Seller of Abracs across the cut-and-grind range. Abracs is a UK abrasives specialist whose product line covers angle-grinder cutting and grinding discs, flap discs, diamond blades, diamond cores, and poly products in the disc diameters and arbor sizes used across trade and industrial workshops. Disc diameters typically run from 100mm and 115mm (small angle-grinder size) through 125mm, 180mm, and 230mm (large angle-grinder size), with thicker bonded grinding discs and thinner cutting-only discs available across the range. Specifications listed on product pages include disc diameter, arbor bore, thickness, maximum operating speed (in RPM), and the material the disc is rated for (steel, stainless, stone, concrete). Match the disc to the tool's RPM rating and the work material — using a disc rated below the tool's RPM is dangerous, and the wrong disc compound on the wrong material reduces cut quality and disc life. Cutting and grinding consumables are a high-frequency reorder line; trade pricing on bulk and case quantities is available — contact the team via WhatsApp 07754288583 for a quote on case-pack and pallet orders. Always observe the tool's safety guidelines: wear eye and ear protection, fit the correct guard, and never exceed the disc's rated RPM.
