There are many router bits of different sizes, shapes, tips, etc. When you go to a store to pick up router bits for the first time, you will be confused because of the vast variety on offer, and some are very identical to each other with very subtle differences. Choosing the right router bit for your project is critical to the success of your woodwork design. Router bits are used along with a variety of routers to get specific profiles. There are a few router bits which are made for a particular purpose, for creating complicated shapes you should use one or more of the 10 Router Bits explains expert guidelines laid out by www.woodmagazine.com.
As explained earlier, the router bits come in different sizes. Optimal speed has to be adjusted in the router to get the desired results. The thumb rule for changing the speed of the router is that if the bit is significant, the allowable speed is low and vice versa.
Straight cutting and spiral cutting bits: These router bits are used when you have to make a dado or a rabbet cut. These bits are the only option for such cuts, and both straight and spiral bits have its advantages. While a spiral bit is more efficient and has less vibration than a spiral bit, they are more expensive when compared to straight bits. Another use of spiral bits is that they are good at plunge routing due to its drill bit motion. Whereas, the straight cutting bits are less expensive, comes in various sizes and is readily available in stores.
Flush trim bits: When you want to trim the edge of one material with that of another, this bit is used. The classic example is that of cutting a flush veneer with a substrate. That trimming is accomplished by using a bearing that is of the same side of the cutter; this bearing can be found either at the top or the bottom.
Edge forming bits: These bits are used when you want to have a decorative border. The S-shaped profile can be cut by using ogee bits; conclave patterns can be achieved by using cove bits. Like flush trim bits, you can find pilot bearings in edge forming bits too. These bits are used in the final stages of your project where a side has already been made and acts as a marker for the bit.
Specialized bits: These bits are used for specific tasks where you need multiple edge profiles in one router bit. When the frame pieces have to be shaped in cabinet doors, etc. stile-and-rail bits are used. Forming the edges of the door panel so that it fits into the rails in the frame is accomplished using raised panel bits. A few other examples of specialized bits are dovetail bits, finger-joint bits, lock-miter bits, etc.
Price an indicator of quality: The general principle is what you pay is what you get. A good quality router bit will be made of superior quality materials which will last longer and more importantly give you the needed precision, good balance and smooth and effortless cutting.
