Power Tools and Their Uses

Drill Press

  • A drill press is a stationary power tool equipped with a drill bit for drilling precise holes in metal workpieces.

Bench Grinder

  • The bench grinder is used for shaping, deburring, and polishing metal pieces.
  • It has two grinding wheels: one for coarse grinding and one for fine grinding.

Angle Grinder

  • Angle grinders are handheld power tools used for cutting, grinding, and polishing.
  • They can be equipped with various attachments for different tasks.

Power Hammer

  • The power hammer is a mechanical forging hammer that uses a non-muscular power source to raise the hammer.
  • It is used to shape large pieces of metal quickly.

Welding Machines

  • Arc welders produce a weld by generating an electric arc between a metal stick (“electrode”) and the metal workpiece.
  • MIG (Metal Inert Gas) welders use a wire welding electrode on a spool to produce a continuous weld.
  • TIG (Tungsten Inert Gas) welders use non-consumable tungsten electrodes to produce the weld.

Bandsaw

  • Bandsaws are used for precision cutting of workpieces.
  • They have a continuous band of blade that rotates on two wheels.

Pneumatic Tools

  • Tools like pneumatic hammers and chisels use compressed air as their power source.
  • The pneumatic hammer is faster and less labour intensive than manual chiselling.

Health and Safety Considerations with Power Tools

  • Always wear necessary protective gear (i.e., safety glasses, ear protection, and dust masks) when operating power tools.
  • Ensure correct setup of the tools and machinery, such as proper blade installments in a bandsaw or the correct electrodes in a welding machine.
  • Only use power tools and machinery for their intended purposes.
  • Regular maintenance of the tools is necessary to keep them in good working order and safe to use.
  • Ensure the work area is neat, clean, and free of clutter or tripping hazards when using power tools.
