Portable machine tools are smaller and easier to use than bulkier tools. They include drills, grinders, sanders, and saws. Care must be taken when using them to avoid injury.
Portable machine tools come in various forms that make tasks such as cutting, drilling or sawing much easier than using bulkier and heavier tools. They can be carried around the work area and are often hand-held, while larger portable machine tools may be supported by other types of equipment. Types of portable power tools include cutting devices such as drills and hacksaws, as well as sanders, grinders, polishers, and other finishing tools. Most of these are either electric or pneumatic.
Portable drills make up a large category of portable machine tools. Each template is designed to work with a certain hole size and is suitable for drilling any smaller hole size. If the machine is used to drill holes larger than intended, the drill may be damaged or there may be a risk of injury to the operator. These drills come in single speed models or those that can be set to different speeds, some models operate at angles and others reverse direction for use with screwdriver attachments.
Portable machine tools for machine shops also include grinders. They can be used to remove unwanted bits of metal from parts after welding, remove rust, and shape and smooth parts. These tools can be operated manually or used with a special holder that holds them in place. They have an abrasive wheel designed to work at high speeds.
Sanders and polishers are portable machine tools that work similar to grinders. These high speed tools are used for surface finishing. A handle is usually included to help hold the unit while working on metal, wood, ceramic, or plastic materials. Various types of sanding discs attach to these tools, and the type of disc used depends on the material the tool is being used to finish.
Portable metal saws are another type of tool used to cut steel pipes and tubes. They are often used by body shops. The hacksaw, band saws and reciprocating saws are hand-operated and relatively light portable machine tools used to cut special and heavy materials. While most portable power tools are hand-operated, great care must be taken when using a professional portable power tool. Operators must be experienced in using them so that the job is done accurately and the chances of injury are low.
