Power Tool Accessories: Your essential buying guide
Start with the accessory fitting and your tool type. Check details such as shank shape, blade bore, disc diameter, sanding pad attachment, battery platform or charger compatibility. An accessory may look suitable but still be unsafe or unusable if the size, connection or speed rating does not match your power tool.
Use wood bits for timber, masonry bits for brick or block, metal bits for steel and suitable specialist bits for tile, glass or concrete. Match the bit diameter and length to the fixing or hole you need, and check whether the accessory is designed for standard drilling, impact drilling or SDS-style hammer drilling.
Check the diameter, bore size, maximum RPM, material suitability and cut type. Wood, metal, masonry and multi-material accessories are not always interchangeable, so choose a blade or disc that suits both the tool and the workpiece. Tooth count, disc thickness and segment type can also affect speed, finish and control.
Yes, batteries and chargers are commonly grouped with power tool accessories, but compatibility is especially important. Check the brand platform, voltage, battery shape and charger type. Capacity can affect runtime and weight, so consider whether you need a lighter battery for quick tasks or a higher-capacity option for longer sessions.
Accessory sets can be useful if you regularly switch between tasks, such as drilling, driving screws or sanding. Before comparing sets, look at the contents rather than the item count alone. A smaller set with the exact sizes and materials you need may be more practical than a large set with duplicate or rarely used pieces.

EinhellPower tool accessories can make a major difference to accuracy, finish and ease of use. The best choice depends on the tool you already own, the material you are working with and whether you need a clean finish, fast removal or long-lasting consumables.
Think about the task first: drilling pilot holes, driving screws, cutting sheet materials, sanding timber, grinding metal or routing edges all require different accessories. Choosing by job type helps avoid poor results and unnecessary wear.
For drilling and fastening, compare bit type, size range, shank style and whether the accessory is intended for impact drivers, combi drills or hammer drills. For cutting and grinding, focus on the material rating and the tool size.
Power tool accessories are not universal. Drill bit shanks, SDS fittings, oscillating multi-tool mounts, circular saw blade bores, sanding pad shapes and battery platforms can vary widely.
If you are replacing an existing accessory, use the old part as a guide for size and fitting. If you are buying for a newer tool, check the tool manual or model information before choosing accessories.
Accessories are usually designed for specific materials such as wood, metal, masonry, plastic, tile or concrete. Using the wrong type can slow the job, damage the workpiece or wear the accessory quickly.
For multi-material projects, compare accessories that clearly state the materials they are suitable for. This is especially useful when working across mixed DIY tasks where one project may involve timber, fixings and masonry.
A coarse sanding sheet removes material quickly, while a finer grit gives a smoother finish. Similarly, saw blades with fewer teeth can cut faster, while higher tooth counts often support cleaner cuts depending on the material and tool.
For regular use, compare construction details such as carbide tips, reinforced discs, heat resistance and storage cases. For occasional DIY, a practical mixed set may offer better flexibility than specialist accessories bought individually.
Always compare accessories with the correct size and speed rating for your power tool. Cutting discs, grinding discs and saw blades should never be used beyond their stated limits.
Also consider dust extraction compatibility, guards, secure fixing and appropriate protective equipment. The right accessory should fit firmly, run smoothly and suit the way the tool is intended to be used.
