Choosing Tool Accessories and Consumables. Choose a consumable for the workpiece material; Check consumable 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 resultFast cutting. Coarse or segmented cutting edge and a disc designed for high productivity. Choose a metal cutting disc · Choose saw-blade tooth countClean cutting. Continuous-rim diamond blade or a saw blade with more teeth. Choose saw-blade tooth count · Choose a polishing discPrecise drilling. Material-specific drill or core bit, accurate centring and stable mounting. Choose a consumable for the workpiece material · Check consumable compatibility with a toolDeep drilling. Bit or core bit with the required working length and effective debris removal. Check consumable compatibility with a tool · Rotational speed (RPM)Rough grinding and stock removal. Grinding wheel or coarse-grit flap disc. Choose a grinding disc · Choose a flap discFinishing and polishing. Fine-grit flap/abrasive disc or polishing accessory.

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 consumable for the workpiece materialCheck consumable 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 CategoriesConsumablesAngle GrindersPolishing MachinesCircular SawsDrillsRotary HammersSafety AccessoriesNext article: How to Check Tool Accessory Compatibility
