Angle grinders
operate at a high frequency which saves electrical costs.
High frequency electrical tools offer greater work capacity than standard electrical tools at roughly four times less the energy costs. Other advantages of high frequency electrical tools include reduced up-front purchase cost, ease of use, maintenance and overall practicality. Suited to continuous use projects in tank, metal and steel construction, these tools can be found in cabinet-making, machine shops, shipbuilding and foundries industries. A large selection of high frequency power tools exist, depending upon construction or machining needs.
Angle Sanders
An angle sander is found in a cabinet shop or a boatyard as its use includes smoothing curved or otherwise inaccessible wood and metal surfaces. Use an angle sander to sand a curved hull or those hard-to-reach places in cabinets or other woodworking projects. Whether taking paint off, sanding wood for painting or buffing a fine finish, an angle sander has multiple uses.
Angle Grinders
Angle grinders use a compressed wire wheel to cut, grind or even polish those tough surfaces on which other sanders have no effect. Used for harder metal or stone surfaces, angle grinders effectively smooth out the rough edges or reduce metal burrs left over during the manufacturing process. These tools exert anywhere between 125-volts, 200 hertz (Hz) and 200-volts and 300 Hz during operation, which is much higher than the traditional frequency of most electrical tools, but at a cheaper operating cost.
Straight Direct Cone Grinders
Designed for the removal of unwanted material, a direct cone grinder uses a carbide burr and mounted cone for grinding. This tool works best on softer metals and minerals. It operates between 100-volts, 220 Hz and 150-volts and 250 Hz.
Direct Die Grinders
A direct die grinder grind plastics, woods and metals. It exerts over 30,000 RPM, making it one of the faster grinders on the market. It cuts with coated abrasives and mounted burrs. You'll find a direct die grinder in a machine shop where its use includes cylinder head porting, engraving and shaping of materials. Exerting more energy than other high frequency power tools with a hertz range between 300 to 450, it still uses high frequency electricity, making it inexpensive to operate in spite of its high performance.
