Battery-powered angle grinderAn angle grinder, also known as a side grinder or disc grinder, is a handheld used for. Although developed originally as tools for rigid abrasive discs, the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.Angle grinders can be powered by an,.
Know Your Power Sanders, And How to Use Them. A tedious chore can be done well, and quickly, with the right tools and the right sandpaper. We'll help you decide whether you need a belt sander.
The motor drives a geared head at a right-angle on which is mounted an or a thinner cut-off disc, either of which can be replaced when worn. Angle grinders typically have an adjustable guard and a side-handle for two-handed operation. Certain angle grinders, depending on their speed range, can be used as, employing a sanding disc with a backing pad or disc. The backing system is typically made of hard plastic, phenolic resin, or medium-hard rubber depending on the amount of flexibility desired. Contents.Uses Angle grinders may be used for removing excess material from a piece.
There are many different kinds of discs that are used for various materials and tasks, such as cut-off discs , abrasive grinding discs, grinding stones, sanding discs, wheels and polishing pads. The angle grinder has large to counter side forces generated during cutting, unlike a power, where the force is axial.Angle grinders are widely used in and, as well as in emergency rescues. They are commonly found in workshops, service garages and auto body repair shops. There are a large variety of angle grinders to choose from when trying to find the right one for the job. The most important factors in choosing the right grinder are the disc size and how powerful the motor is. Other factors include power source ( or electric), and size.
Generally disc size and power increase together. Disc size is usually measured in inches or millimetres. Common disc sizes for angle grinders in the United States include 4, 4.5, 5, 6, 7, 9 and 12 inches. Discs for pneumatic grinders also come much smaller. Pneumatic grinders are generally used for lighter duty jobs where more is required.
This is likely because pneumatic grinders can be small and light yet remain powerful, because they do not contain heavy copper motor windings, while it is harder for an electric grinder to maintain adequate power with smaller size. Electric grinders are more commonly used for larger, heavy duty jobs. However, there are also small electric grinders and large pneumatic grinders.Safety. A video on vibration research done on pneumatic grindersThrough a sound pressure level and vibrations study conducted by the, grinders under an unloaded condition ranged from 91 to 103. In addition, angle grinders produce sparks when cutting ferrous metals. They also produce shards cutting other materials.
The blades themselves may also break. This is a great hazard to the face and eyes especially, as well as other parts of the body, and as such, a full face shield and other protective clothing must be worn. Angle grinders should never be used without their guard or handle attached; they are there as a necessary precaution for safety. All work should be securely clamped or held firmly in a vise.History The angle grinder was invented in 1954 by German company Ackermann + Schmitt in. Owing to this, in German, Dutch, Slovak, Czech, Polish, Croatian, Latvian, Romanian, Hungarian and Bulgarian (and possibly in other European languages), an angle grinder is colloquially called just a 'flex'.See also.References Wikimedia Commons has media related to.
