Choosing Tool Accessories and Tool Accessories. Choose a tool accessory for the workpiece material; Check tool accessory compatibility with a tool; Choose dry or wet operation; Rotational speed (RPM).ToolsArmenia: Define the result first, then verify material, tool, dimensions, RPM and operating method.Choose for the required resultDry operation. Accessory explicitly approved for dry use with dust extraction. Choose a metal cutting disc · Choose saw-blade tooth countWet operation. Accessory and tool approved for water-fed use. Choose saw-blade tooth count · Choose a polishing discFast cutting. Coarse or segmented cutting edge and a disc designed for high productivity. Choose a tool accessory for the workpiece material · Check tool accessory compatibility with a toolClean cutting. Continuous-rim diamond blade or a saw blade with more teeth. Check tool accessory compatibility with a tool · Rotational speed (RPM)Precise drilling. Material-specific drill or core bit, accurate centring and stable mounting. Choose a grinding disc · Choose a flap discDeep drilling. Bit or core bit with the required working length and effective debris removal.

Start with a coarser grit and progress through finer grits in stages.Is a long drill bit enough for deep drilling?No. Correct diameter and mounting, tool power, debris removal and the manufacturer-approved mode are also required.If the task is clear, must compatibility still be checked?Yes. The goal does not replace checks for material, mount, size, RPM and operating method.Read AlsoChoose a tool accessory for the workpiece materialCheck tool accessory compatibility with a toolChoose dry or wet operationRotational speed (RPM)Choose a metal cutting discChoose a grinding discChoose a flap discChoose a polishing discChoose saw-blade tooth countRelated CategoriesTool AccessoriesAngle GrindersPolishing MachinesCircular SawsDrillsRotary HammersSafety AccessoriesReturn to: Tool Accessories
