A dual-sided grinder is an electrical grinding device consisting of an electric grinding face that rotates counterclockwise and a rotating face that rotates clockwise. The first rotating face generally is called a fixed face; the second rotating face is called a variable face and it features an auger attachment to chisel or mill the material, and a clamp on the working end that holds the piece in place. There are some variations on this design including hand grips extending over one hand, hands that resemble a pair of tongs, or the presence of an adjustable wrench.
There are many differences between the different models of the two-sided grinders. Some models feature a handle on one end that allows a handle with a finger guard, while others are mounted directly on the grinding unit and can be removed and put back into place. The adjustable face designs are designed to be held by the hand as it moves across the surface of the work piece. The variable face designs allow the grinding device to be moved and adjusted to meet the needs of the user.
Two-sided grinders vary greatly in cost. Some models may cost in the hundreds of dollars, while others can be purchased for a few hundred dollars and still remain within the price range of most kitchen and bathroom remodel projects. Most two-sided grinders come with a two-year limited warranty. Some models can be upgraded to a three-year limited warranty. The warranty information can be located on the manufacturer’s website.
There are some who prefer the use of these types of grinders because they are more convenient. These grinders do not require assembly, which can make cleaning them easier. They can also be used to grind small pieces of food and drinks or small nails that often find their way into jewelry boxes, so that a surface is always protected from scratches. They are often stored outside the home for a variety of reasons; this keeps them safe from dust and dirt that could ruin a beautiful surface.
Because two-sided grinders require the use of two hands, the person grinding should always have at least one free hand to handle any additional tools, such as a nail file or a grinder tool. It is essential that the two work sides are parallel to each other when operating the grinding, or else the person using the grinder may get a shock and be injured. If the face of the grinding unit is not parallel, the two ends will not be parallel to the wood surface or floor, making the working surface uneven when the two sides are turned together.
Grinding should be done only at an angle of 90 degrees or better to avoid damage to the wood. If possible, use coarse sandpaper to remove as much material as possible without causing injury. For larger pieces, use a paper towel to gently buff away any loose materials.
