Power tools

Choose a power tool by the job it must repeat. Drill machines are rated by chuck capacity, angle grinders by disc diameter and spindle speed, and rotary hammers by chuck type and impact energy, so state the material being worked, whether masonry, steel or timber. Confirm the wattage, corded or cordless operation, and the battery voltage and pack size for cordless models. Impact drivers need the bit and socket fitting mentioned as well.
