Maintaining the structural integrity of your drilling tools is one of the most important factors in performing at a professional level. However, many DIYers and even pros have a tendency to ignore the constant wearing down (dulling) of their iron based drill bits. This is exactly why we created the Portable Diamond Drill Bit Sharpener. Utilizing a high quality Corundum Grinding Wheel, our sharpener will provide the user with a simple, efficient and convenient way to keep their irons from getting too worn out. Our product is made specifically for all types of irons and they works by allowing the abrasive qualities of Corundum—A very hard and durable crystal formed from Aluminum Oxide—to grind away the dulled areas of your drill bits and making them sharp again.

By adding this tool to your daily drill bit maintenance routine and you should notice a dramatic increase in how long your drill bits last. Also since you will not need to apply as much pressure to get through thick materials and you will not generate as much heat inside the holes drilled. Heat generated during the drilling process can cause the drill bit to fail.

One of the best things about this sharpener is how easy it is to use and how portable it is. Unlike industrial bench grinders that require a great deal of room to operate and a lot of practice to learn how to properly hold the drill bit at the correct angle, this unit operates right off of your existing electric or battery operated drill. It has a standardized hexagonal shank that allows the sharpener to fit into virtually any drill chuck, turning your hand held drill into a precision grinder. The sharpener also comes equipped with built in guides to assist in holding the correct relief and rake angles that are the hardest part of sharpening a drill bit on your own. Once you insert the drill bit into the pre determined slot and the spinning Corundum wheel will begin to grind away the dull, rounded edges of the cutting surfaces and giving back your drill bits original sharp tip and ensuring that they track true as soon as they hit the work piece.

As noted earlier and this sharpener was specifically developed for sharpening irons made of Iron based metals (that is High Speed Steel or Carbon Steel). Due to their relatively low hardness levels and these metals respond extremely well to the Grit found in the Corundum wheel, providing just enough friction to sharpen the metal without being aggressive enough to remove too much material or ruin the temper of the drill bit. Although this sharpener does an excellent job at giving an edge to standard metal working and wood working drill bits, it is normally not suitable for high hardness Carbide or Ceramic type drill bits that require specialized Diamond Abrasives. For the average Workshop however, where Irons are used in nearly every project, this Tool represents a money saving option. Rather than throwing away your drill bits once they become dull and no longer perform like new, you can restore them to near new condition in just a few seconds, thus eliminating waste and continuing expenses associated with purchasing replacement drill bit sets.

In addition to the financial savings provided by a portable Corundum Sharpener, using a sharp drill bit directly relates to both safety and accuracy. Drilling with dull bits tends to allow the drill bit to "walk" across the surface of the material it is drilling into, which may result in unattractive scratch marks on the finished work piece or incorrect hole placement. Additionally, dull drill bits require significantly more downward pressure when drilling through a variety of materials which increases the likelihood of either the drill bit breaking apart or the drill itself slipping. With a portable Corundum Sharpener at your disposal, you can rest assured that your cutting operation remains consistent and predictable. The small size of the accesssory makes it possible for it to live in your tool bag or drill case at all times; therefore, you always have what you need to make a quick touch up in the middle of a job.
