The ZX 1000 electric 1_______ has two speeds: the fast speed is 3,000 rpm and the slower speed is 1,000 rpm. Adjust the speed according to the 2_______ of material and the size of the hole. For example, use the faster speed for a soft material such as 3_______ to drill holes smaller than 10 millimetres (10 mm) in diameter but choose the slower speed for holes between 10 and 25 mm. However, for steel, a 4_______ material, use the faster speed for holes smaller than 6.5 mm and choose the slower speed to drill holes between 6.5 and 10 mm.

What is the slower speed of the ZX 1000 electric drill?
The ZX 1000 electric drill has two speeds: the fast speed is 3,000 rpm and the slower speed is 1,000 rpm. Adjust the speed according to the type of material and the size of the hole. For example, use the faster speed for a soft material such as wood to drill holes smaller than 10 millimetres (10 mm) in diameter but choose the slower speed for holes between 10 and 25 mm. However, for steel, a hard material, use the faster speed for holes smaller than 6.5 mm and choose the slower speed to drill holes between 6.5 and 10 mm.

What is lead monoxide used for?
Lead is now a very expensive metal. At one time it was used extensively for roofing and for water piping because of its softness and resistance to corrosion. But later copper and iron have taken its place. Lead is a grey malleable metal which melts at 327 ̊C, which is low for a metal. Lead is still used for roofing and for making waste pipes and sink traps because it is easily bent into shape; storage battery (accumulator) plates; storage tanks for sulphuric acid; lead shot; solder; screens to stop harmful radiation from radioactive substances. Lead monoxide is used for making glass that is brilliant and sparkling, i.e. decorative tableware.

Where are steels of low carbon content used?
The most important metal in industry is iron and its alloy – steel. Steel is an alloy of iron and carbon. It is strong but corrodes easily through rusting, although stainless and other special steels resist corrosion. The amount of carbon in steel influences its properties considerably. Steels of low carbon content (mild steels) are quite ductile and are used in the manufacture of sheet iron, wire and pipes. Medium-carbon steels containing from 0.2 to 0.4 per cent carbon are tougher and stronger and are used as structural steels. Both mild and medium-carbon steels are suitable for forging and welding. High-carbon steels contain from 0.4 to 1.5 per cent carbon, are hard and brittle and are used in cutting tools, surgical instruments, razor blades and springs. Tool steel also called silver steel, contains about 1 per cent carbon and it is strengthened and toughened by quenching and tempering.
