TOOLS:

A drill is a tool that you use to drill holes in materials. You should always hold it with one hand on the triger and one hand stabalizing it. The best way to drill, is by lineing up your shoulder with your grip. Never stop drilling while drilling because you could break the the material and/or the tip.

A file is a tool that only files medal. You line it stright with your piece of medal, then file back and fourth until the sharp edges go away. For example: when you file your nails you line it evenly to your nials and file.

A saw is a tool that you use to cut through wood. When useing a saw you hold the handle and on the top egde you stabalize it with your hand. Don’t put pressure because you can bend the saw and break it.

A clamp when using a clamp you simply clamp your object, so that you can cut, drill, hammer, etc. and it will be stabled

TIP: WHEN USING ANY TOOL MAKE SURE YOU WEAR SAFTY GOGGLES, AND THAT ANYTHING LOSE IS PUT AWAY. ANY LONG HAIR SHOULD BE PULLED BACK AND TIED SO IT WON’T GET COUGHT IN THE TOOL!!!!!!!!
