Heavy-Duty Power Tool
Considerations
• Power tools designed for professional use are
different than those designed for home use
– Bearings on a drill motor: located at the front and
rear of the motor armature
• Types: ball, roller, and powdered metal sleeves
– Drill chuck: made of case-hardened steel
– Housing: usually Super Tough™ nylon
– Power cord: usually eight to ten feet

Heavy-Duty Power Tool
Considerations (cont'd.)
• Battery-operated tools
– May have a adjustable clutch
– Fully discharged batteries accept a charge more
fully
• Grinder
– Typically has a wheel on one side and a wire
brush on the other
• Grinder sharpens tools
• Metal being ground must be quenched

Other Electric Equipment
• Battery chargers
– Charge batteries and help start engines
– Some recommend against using the unit for
starting the car
• Soldering tools
– Include soldering iron, gun, and pencil
– Melt solder to join electrical wires

Other Shop Equipment
• Bench vise
– Every shop has a vise
– Jaws usually have teeth
– Brass jaw caps prevent vise from marring
workpiece
• Engine analyzer
– Diagnoses engine problems (e.g., compression,
cylinder balance, worn timing chains, etc.)
• Tire changer
– Uses air to unseat tire bead from the wheel rim

Welding Equipment
• Arc welding
– Inexpensive and fast, but requires 220-volts
– Electric arc melts metal when electrons flow
across the arc
• MIG welding
– An inert gas shield is applied around arc area to
prevent oxidation of the metal
• Oxyacetylene welding
– Oxygen and acetylene are mixed and ignited
– Intense heat melts steel for welding or cutting
