There are different types of routerbits. Some are used for simple operations, while others are forspecialized uses. It is necessary to know the kind of router bit youare buying. These are the commonly used types:Straight router bits arevery common, so you have probably heard of them or seen one. Theirpurpose is to cut straight down into a wood or other material toform a hollow that will serve as an inlay or mortise. Straight onesmay have variations in diameter, mostly between 3/16 and 1 ½.Rabbeting bits are used to cut amaterial vertically and horizontally along its edge. A rabbeting bithas a bearing on top that serves to guide the bit as it cuts alongthe edge of the wood. Another type is the flush trimone. This also has a pilot bearing and is also used to trim theedges of materials. The pilot bearing may be located in differentparts of the bit. It may be on the top or at the base. A chamfer router bit producesangular trims to enhance the appearance of the edges of materials. The edge forming type is usefulwhen you want the edges of materials to have curves and otherdesigns. There are different types of edge forming bits. Examplesare round over and edge beading ones.Molding bits have a similarfunction as the edge forming ones, but they are bigger in size.Thus, they are used on a router table instead. Stile and rail ones are used formaking frame members of passage doors or cabinet doors. They aremainly for construction of frames and panels.Raised panel bits are usedtogether with stile and rail bits when doing work on the edges ofdoor panels. These come in two typesvertical and horizontalraised panel bits. While the vertical raised panel ones are safer touse due to their smaller size, the horizontal type is important increating curved edges.A router bit may have a shank diameterthat is either a quarter of or half an inch. The half-inch shank onesare preferred to the other, because its surface area is four timesbigger. The ½ shank bit is more rigid and offers more supportwhen cutting edges. However, there are those with an 8 mm shankdiameter and others with a 30 mm diameter. Routers have a speed range of 8,000 24,000 rpm. Since bits cannot be run on a single speed, adjustment isnecessary. Good routers have speed adjustment feature to accommodatedifferent types of bits. Generally, the wider the bit is, the lowerthe revolutions per minute to be employed. A router bit does comewith a specified maximum rpm, which is the maximum speed that it canbe operated. Check for prices when buying bits.However, besides looking at the price, also look at the quality. Agood quality router bit will last a long time. Those with a goodquality also produce less vibration and greater cutting efficiency.Look for reputable suppliers and check out their auto shippingpolicy, especially if you are buying online.
