Angle Grinder / Polisher Accessories

To achieve optimal results with angle grinders and polishers, you need the right accessories. With grinding discs and sandpaper in various grits, you can remove rust or create fine, smooth surfaces. If you're polishing your car to restore its shine, you'll need the appropriate polishing bonnets for your polishing machine. Angle grinders are versatile tools with a similarly extensive range of accessories. Whether cutting discs, abrasive discs, grinding discs, or stands for stationary use – here, you'll find the right accessory for every application.

Overview of Accessories for Angle Grinders and Polishers

Attachments for Polishers & Grinders

With the right attachments for polishers and grinders, surface treatment becomes effortless – especially for car care or restoring older vehicles. Useful attachments include sets of polishing pads or bonnets made of textile and synthetic materials, each serving specific purposes. The textile bonnet is used to apply and evenly distribute polishing compound, while the synthetic bonnet brings out a high shine on the surface. For the matching backing plate, sandpaper in various grits is essential. Coarse-grit sandpapers are ideal for removing rust and old paint layers, while finer abrasives create a smooth, polish-ready surface. With these attachments, DIY enthusiasts can maximise the performance of their grinder or polisher, achieving professional-quality results.

Grinding & Cutting Discs for Angle Grinders

An angle grinder is a true multitool – depending on the disc used, it can grind, scrub, or cut. The Einhell range offers a wide selection of cutting discs, available both in convenient sets and individually. These discs vary in diameter, thickness, and material, allowing for optimal selection based on the task. Diamond cutting discs are ideal for particularly hard materials like tiles or stone, effortlessly cutting through tough surfaces. Flap discs, also known as fan grinding discs, are perfect for rust removal and smoothing weld seams. Their unique design enables even material handling and a fine finish. Whether for rough prep work or detailed finishing, the right disc maximises the angle grinder’s performance and supports every project.

Angle Grinder: Handling Accessories

For easy and flexible handling of angle grinders, the right accessories are essential. The Einhell range includes practical extras like the quick-release nut and cutting stand, enhancing comfort and versatility. The quick-fix nut allows for fast and effortless disc changes – no pin spanner required. This makes swapping grinding and cutting discs quick and easy, significantly improving work efficiency and convenience. With the cutting stand, the angle grinder also transforms into a stationary device, suitable for use as a metal cutting machine. In this fixed position, it’s perfect for precise cuts in metal and other materials requiring stable guidance. These accessories make the angle grinder an even more versatile tool, facilitating its use across various projects.

Basic Knowledge on Cutting & Grinding Discs

To achieve optimal results with an angle grinder, choosing the right cutting or grinding disc is essential. One of the key technical specifications is the diameter (Ø) of the disc, which must match the tool. Common diameters include 115 mm, 125 mm, 150 mm, and 230 mm. Each size is designed for specific tasks and machines, so it's important to always follow the manufacturer's recommendations. The thickness of the cutting disc also matters: thinner discs are ideal for fine cuts with minimal material loss, while thicker discs are more robust and durable. An angle grinder always removes material, leading to some degree of material loss. Cutting discs designed for material removal also wear down during use. When a disc becomes significantly worn—such as being much smaller than its original size—or its cutting performance declines, it should be replaced immediately to ensure safe and precise work.

Which Cutting Disc Is Best for Which Material?

The choice of cutting disc depends on the material you intend to work on. Diamond cutting discs are especially versatile, as their diamond edge makes them extremely hard and durable. The edge can be continuous, serrated, or segmented – ideal for materials such as stone, concrete, tiles, ceramics, porcelain stoneware, marble, and granite. A segmented edge disc is ideal for fast, rough cuts, a turbo edge (serrated) for relatively fine cuts at medium speed, and a continuous edge for slower, precise, and as fine cuts as possible. For metalwork, cutting discs made from aluminium oxide are commonly used and are well-suited for steel and other metals. Each disc is specifically designed for particular applications and maximum rotation speeds, which are always indicated on the packaging. With the right cutting disc, an angle grinder operates efficiently and safely, ensuring precise cutting results.

Sandpaper and the Different Grit Levels

For various surfaces and tasks, there is suitable sandpaper available in different grit levels. The grit is indicated by "P" (according to FEPA standard) or "K" (according to the American CAMI standard) followed by a number: the higher the number, the finer the abrasive finish. Common grits like P600 or P800 are ideal for sanding paint or preparing for a new coat, while P1000 or P1200 are used for fine interim sanding or pre-polishing. Very fine grits such as P2000 or P3000 are perfect for polishing, creating smooth, glossy surfaces. For woodwork, coarser grits are often used to remove unevenness, while for paintwork, a fine grit is preferred for optimal results. As a tip: sandpaper should be replaced when it feels smooth and its sanding performance noticeably declines – you’ll notice this when you need to apply more pressure to remove material or if the sanding becomes uneven.

Easy Attachment Changes

For quick and efficient work with polishers, grinders, or angle grinders, it’s important that attachment changes are simple and swift. Many backing pads are equipped with convenient hook-and-loop fastening, which holds the sandpaper securely while allowing for easy removal. For angle grinders, a quick-fix nut further simplifies disc changes. This nut can be tightened and loosened by hand, eliminating the need for a pin spanner. However, if a particularly firm hold is needed, the pin spanner can still help to secure the quick-release nut tightly. These flexible, easy mounting options enable fast changes between various discs and abrasives, saving time and significantly enhancing efficiency and precision on the job.
