How To Use a Die Grinder

The die grinder is a power tool designed to function as a polisher and buffer for areas within cylinder-shaped objects. A grinding nose attachment fastens itself below the grinder, similar to how a drill bit attaches to a drill, works on smoothening the edges of cut metal piping, and sanding off tiny spurs caused by the cutting process. When these bits and pieces are removed, they are much easier to install. The die grinder utilizes several types of bits for grinding, depending on the type of job that need to be done. To use this device, it is best to have some knowledge of how it needs to be operated. When used incorrectly, it could wear down the die grinder and may also injure the person operating it. Study the steps listed below to make good use of the die grinder and produce positive results.

  • Safety measures to take. Whenever you handle any type of power tool, always place your safety on top of your priority list. With the die grinder, you will need to take certain precautionary measures so as to avoid any accidents from happening any injuring you in any way. Remove any type of hanging jewelry on your person while handling the tool, such as necklaces or bracelets. These pieces could get caught into the die grinder and cause serious injuries. It is also advised that protective goggles are used to keep the eyes safe from harm’s way as well. The tool must also be held on to firmly and securely while in operation so that you are able to maintain complete control over it.
  • Keep the object you are working on securely in place. Make sure that the object that you will be grinding remains firmly in place as you work on it. If it moves while the grinder is in operation, it may cause you injuries, or cause damage to the object you are working on
  • Attach the grinding bit properly. Open up the collet of the die grinder, which is where the grinding bit is inserted, by turning it counter-clockwise in a single rotation. Use a spindle lock wrench to be able to do this. Place in about ¾ of the bit’s shank on the collet which has been opened up. Turning in a clockwise motion, tighten up the collet with the spindle lock wrench.
  • Operate the die grinder. Turn on the power switch of the die grinder. Get a good grip on the tool and press down on the grinding bit carefully over the edge of the particular piece of metal you would like to take off. Now work around the area carefully and avoid adding extra force, as your die grinder is capable of effectively doing the job, while using up its own rate of speed. Once done, take off the bit from its attachment on the collet. Clean up your die grinder to ensure that there are no excess particles attached to it from the grinding process.

The die grinder is also an ideal tool to use when you are doing some engraving work. It can also help a lot when shaping not only metal, but wood or plastic materials too.
