Hand and Power Tool Repair Services Information

Hand and power tool repair services specialize in the repair and maintenance of hand-held air, electric, and manually-powered tools. Hand tool repair services fix manually-operated tools such as calipers, hammers, screwdrivers, and wrenches. The power from these tools derives from their operator. Power tool repair services fix implements that derive their power from pneumatic or hydraulic pressure, or an electric motor. With pneumatic hand tools, compressed air is used to bring a greater force to the tool. With hydraulic hand tools, the additional force is transferred to the tool from an incompressible liquid, generally oil.

Hand and power tool repair services differ in terms of capabilities. Some companies specialize in the repair, replacement, or modification of pneumatic tools such as air hammers, air ratchets, airbrushes, jackhammers, sandblasters, or paint sprayers. Other pneumatic power tool repair services fix pneumatic drills, grinders, sanders, screwdrivers, tapping machines, and nail guns. Hydraulic tool repair services are also available. These companies specialize in the repair, replacement and modification of hydraulic power tools such as hydraulic lifts or jacks, hydraulic presses, and hydraulic robots. They may also fix hydraulic hand tools such as drills, hammers, grips and lifts that are used to form or shape pipes or tubes.

Electric power tool repair services can repair or replace the electric motors that are used in various types of powered tools. Most electric power tools use universal, split-phase induction, or capacitor start motors. Although most universal motors are designed to use alternating current (AC), some may be operated with a DC power supply. Induction motors are similar to induction motors, but can run for only relatively short periods of time. Some electric power tool repair services specialize in fixing capacitor start motors, which are similar to inductor motors but use a rotary instead of a linear field. Specialty hand and power tools repair services are also available.

Hand and power tool repair services may fix or modify products according to specific standards. Several organizations maintain quality standards for power tools. These include the International Organization for Standardization (ISO), the National Fluid Power Association (NFPA), the American National Standards Institute (ANSI), and the National Electrical Manufacturers Association (NEMA). Underwriters Laboratory (UL) and the Canadian Standards Association (CSA) also publish standards for hand tools and power tools that are used in various applications and industries.
