Drilling and screwing
Audio for slide 1 (mp3 |6|KB)
In the workshop, most of the holes are produced by static machines while the components are being manufactured.
But out at the jobsite, you'll have to drill all of the holes yourself with a hand-held drill.
You'll also use a cordless drill constantly to insert screws. And for more delicate jobs and adjustments of hardware items, you'll need a set of screwdrivers. Below are the main items of equipment used for drilling and screwing.

Learning activity
Audio 6 (mp3 |6|KB)The most common screw heads you're likely to come across are Phillips and slot head. But there are other types of screw heads.
Can you name any of these more specialised screw heads?
Write down the names in your workbook. For each one you identify, provide a brief description of where that type of screw is used.
