A detailed buying guide: how to choose a consumable for the workpiece material.
This section brings together replaceable consumables for corded, cordless and pneumatic tools — for builders, metalworkers, woodworkers and home users. Diamond discs cut stone, concrete, tile and asphalt, while abrasive cutting discs and grinding discs for angle grinders cut and clean metal. Drill bits and chisels for rotary and demolition hammers handle drilling and demolition of concrete and brick, and diamond core bits make large-diameter holes. Milling cutters shape edges, grooves and profiles in wood. The tools themselves, as well as screwdriver bits, attachments and other accessories, are found in separate sections. See how to choose a consumable for the intended task.
Choose a consumable first by the job (cutting, grinding, drilling, demolition, routing) and the workpiece material — metal, stainless steel, concrete, reinforced concrete, tile or wood. Universal discs suit occasional work, while specialised ones cut faster and last longer. On compatibility, see how to check consumable compatibility with a tool.
Common angle grinder disc diameters are 115, 125, 150, 180 and 230 mm with a 22.23 mm bore, and the disc must not exceed the size of the tool guard. For drill bits and core bits check the diameter, working length and shank. Read how to choose the correct accessory size.
Diamond discs come as segmented (concrete, stone), Turbo (universal) and continuous rim (tile, ceramics), and the segment height and bond determine service life. Wet cutting reduces dust and heat, while dry cutting requires regular pauses. See how to choose a diamond disc and dry vs wet operation: how to choose the correct method.
Abrasive cutting discs are usually 1.0–2.5 mm thick: a thin disc cuts fast with less heat, while a thicker one lasts longer. Choose grinding discs (6–8 mm) and flap discs by grit and material, and never grind with the side of a cutting disc. Read how to choose a metal cutting disc and how to choose a grinding disc.
Diamond core bits make round holes in concrete, brick and tile — from about 68–82 mm for socket boxes to 100–200 mm and more for pipes and ventilation. Check the shank thread (M14, 1 1/4" UNC, SDS) and whether the bit is designed for wet or dry drilling. See how to choose a diamond core bit.
Drill bits and chisels must match the tool shank: SDS Plus for light and medium rotary hammers, SDS Max for heavy ones and HEX for demolition hammers. Choose chisels by shape (pointed, flat, wide) and length, and drill bits by carbide tip and number of cutting edges. Read differences between SDS plus, SDS max, and HEX systems and how to choose a rotary hammer chisel.
Choose milling cutters by shank diameter (6, 8, 12 mm or 1/4", 1/2"), which must match the router collet, and by profile — straight, edge, round-over, chamfer or groove. Carbide (HM) cutters suit chipboard and hardwood, and large-diameter cutters require reduced speed. See what is rotational speed (RPM).
The maximum speed or peripheral speed marked on the disc (for example 80 m/s) must be higher than the tool speed, and expired or damaged discs must not be used. Before installation, unplug the tool, clamp the disc with the correct flange and work with the guard, safety glasses and gloves. Read how to read disc markings and how to install and replace an angle-grinder disc.
At ToolsArmenia you can compare consumables by type, workpiece material, diameter, bore or shank and choose the right consumable for your tool and job.
