Round-over bits basics. Round nose bits, sometimes referred to as core-box bits, can be used to cut shallow, rounded-bottom grooves of various depths, but to be used properly, the roune should be plunged until the profile cut into the rouuter creates a full degree arc.

Chamfer bits are versatile, in that one bit can create several different-size chamfers based on the depth of the cut. As with the beading bit, some chamfer bits have a bearing-tip that rides along the edge of the stock. A cove profile is designed to apply a concave, rounded profile. Often, the cove bit is used to match a beading or roundover shape on the corresponding piece of stock.

For instance, drop-leaf tables use matching cove and bead profiles called a rule joint. The cove bit often has a bearing-tip for riding along the edge of the stock. Tip: The cove profile is not to be confused with a round nose bit below , which is used to make round-bottomed grooves in the middle of a piece of stock. There are several methods that can be used to cut a dado profile, which is a square channel in the middle of a piece of stock.

While there are specialty saw blades used for cutting dadoes on a table saw , a dado can also be cut with a router using any of a variety of straight-cutting bits. These straight-cutting bits come in a variety of sizes, they are all similar in that the bit is designed to cut a flat bottom and square sides.

Some straight-cutting bits have a bearing-tip designed for trimming a piece of laminate applied to the face of a board , but these bearing-tip bits cannot be used for cutting a dado. The dovetail bit is most famous for use in creating tails for dovetail joinery. However, dovetail bits can also be used to make tapered dadoes and rabbets. A dovetail profile has a flat bottom with angled sides which are wider at the base. Most dovetail bits do not have a bearing, although a few specific template-style dovetail jigs require bearing on the shank of the bit.

The Ogee bit, also referred to as a Roman Ogee creates a compound, S-shaped profile. There are several variations on the Ogee profile, with shoulders on the edges or points in the middle of the profile.

As with other edge bits, Ogee router bits often come equipped with a bearing tip. Simply stated, a rabbet is a dado on the edge of a piece of stock. While rabbets can be cut using a table saw with a dado blade or a straight-cutting router bit, there are also specially-designed rabbeting bits, designed to ride along the edge of the stock often with a bearing tip. The round nose router bit is similar to the cove bit, except that it is designed for plunge routing grooves and flutes in the middle of a piece of stock.

Round nose bits, sometimes referred to as core-box bits, can be used to cut shallow, rounded-bottom grooves of various depths, but to be used properly, the bit should be plunged until the profile cut into the wood creates a full degree arc.

As mentioned above, the roundover bit creates a rounded profile on the square edge of a piece of stock and differs from the beading bit in that no shoulders are cut. Often, only a portion of the roundover bit is used to create a partial easing of the edge rather than a full degree arc. Whiteside offers a variety of spirals in up-cut, down-cut, and compression flute configurations. We recommend up-cut spirals for best control of your router and ejecting chips up and out of your dado cuts.

Down-cuts provide superb control of fraying on the surface nearest the router while preventing the tendency to lift small workpieces. Compression spirals have up and down flutes to maintain the cleanest cut on both the top and bottom of the workpiece.

Whiteside increases the life and value of your spiral selection by offering these bits in a solid carbide form. Whiteside is proud to supply the industry with our superior line of drilling and boring tools. We offer a range of countersinks manufactured with standard carbon steel or superior high speed steel for extended life. Three wing drills and patented carbide-tipped hole saws are among our line.

Many of these tools were designed and tested by consulting experts in the marine industry. A standard router bit begins as no more than a piece of steel. Steel is purchased in foot long bars and self-fed into a machine that cuts them to the appropriate length. As the cylinder-shaped pieces are cut, they are gathered and sent to the lathes. The lathes run each piece of steel with precision accuracy to shape the general form of the bit and create the shank. Every size and type of router bit has a program to provide the specifications of the tool being manufactured.

The shaped piece of steel - or a blank - is then sent to the mills. Mills are used to cut the flutes into the blank. A router bit will commonly have one to four flutes, all of them cut at this stage in the process.
