When drilling blind holes in iron or steel, fine metal bits usually fall into the hole. To remove them, you can use a strong magnet and a soft iron or steel rod that is smaller in diameter than the hole. Push the rod to the hole bottom, then press the magnet to its upper end. Keeping the magnet to the rod, pull it out of the hole and brush away the bits of metal. Repeat until all of the metal bits are removed.
Before you tear into a repair job, start by checking for the simplest cause instead of assuming the worst. For example, before replacing fuses or breakers, first check for burned-out bulbs. If a faucet is working poorly, check for debris lodged in the faucet’s aerator before tearing the faucet apart. Likewise, first make sure equipment and appliances are plugged in. By checking for the simple causes when a problem occurs you can save yourself from wasting time, effort and money in making unnecessary repairs.
