What is an Edge Forming Router Bit?

Created to lower, throw over saddlebags and trim supplies like wooden and plastics, there are a lot of distinct kinds of router bit circulating the woodworking and manufacturing industries. Among the most widespread and popularly used router bits is a sub-group referred to as edge-forming bits. As that identify implies, these bits are practically singularly utilised to produce an decorative shape on the edge of a workpiece. Notably well-liked in cabinetry and carpentry edge forming bits are developed with a massive selection of profiles and can be fabricated to match almost any profile conceivable. The profile of a router little bit, then, is the condition of its enterprise end (or, the cutter) and of the design and style or edge it then produces by reducing that condition/profile into a workpiece.

Edge forming bits can be everywhere from widespread to sophisticated and frequently boast intricate profiles that produce an ornate and unique shape to a workpiece. Since these router bits are usually used to create the quite ultimate decorative components on a workpiece, they are frequently utilised with a pilot bearing for direction. In the long run, made to inject character and drama into tasks like fine home furniture, and with a almost limitless array of profile styles and dimensions, edge forming bits can carve traces to convey antique, vintage, classic, modern or and so forth, themes to your function. They are the finishing contact and can subtly or exuberantly increase your workpieces.

Like other router bits, edge forming bits can be discovered in varying characteristics and constructions. HSS (higher velocity steel) bits are the least expensive and are, accordingly, the most brittle and breakable. Carbide tipped bits are the most commonly utilised variety of little bit as, although they are a little bit much more costly than HSS bits, they are considerably a lot more durable and better retain their cutting edge. Because of their high-top quality cutters, these bits complete all purposes reasonably if not incredibly effectively. The most elite and costly type of little bit, then, is an totally carbide little bit. Though these bits offer the most exceptional chopping and toughness, simply because they are so expensive, they are normally used by only the most seasoned crafters.

The underneath checklist reflects the most typical types of edge forming router little bit and briefly discusses their profiles and specs (if applicable):


Bead and Double Bead Router Bits:
Bead bits create a convex (rounded, hump-like) quarter-spherical profile. Double bead bits (and so forth as you may well come across triple bead bits and and so forth) generate this quarter-round 2 times with one particular hump directly under the other.

Bullnose Router Bits:
Bullnose bits create a complete 180-diploma (half-spherical) convex spherical over on the edge of a workpiece. Bigger flats or fillets sit over and underneath the round over and are generally increased than the spherical above by itself. These bits need to be utilized with a fence or edge manual.

Chamfering Bits:
Chamfering bits develop a extremely thoroughly clean beveled cut. These bits are accessible in a variety of angles and generate a basic completed edge. Some chamfering bits also incorporate a flat shoulder which permits consumers to include a flat formation at the prime of the angled cut.

Classical Bead and Cove Router Bits:
Bead and cove bits combine a bead (convex – a hump) and and a cove (concave – a cave) formation exactly where the bead sits atop the cove they are separated and bracketed by single fillets.

Classical Cove and Bead Bits:
Cove and bead or cove and round in excess of bits are primarily the exact opposite or “flip” of earlier mentioned profile combining a cove and bead (or spherical above) formation. The concave and hump styles tumble in that sequence and are in the same way divided and bracketed by solitary fillets.

Cove and Double Cove Router Bits:
Cove bits are used to develop a concave quarter-spherical (a curved indent or cove/cave shape) into the edge of a material. Like double beading bits, double cove bits (and so forth) create a profile in which this cove condition doubles in excess of itself stacking a single cove atop one more.

Edge Beading Router Bits:
Edge beading bits make fifty percent-spherical (50 percent-circle – a hundred and eighty-degree hump) profiles referred to as “beads.” The bead is typically bracketed by flats or fillets.

Handrail Router Bits:
Handrail bits are utilized to create the beneath-reduce section of a handrail. Though they can be utilised with several edge forming bits, they are ordinarily used in conjunction with table edge bits to generate a workpiece that is profiled on the facet and top. These bits ought to only be utilised with a router table.

Ogee Router Bits:
Ogee bits generate an “S” shaped profile on a workpiece and, accordingly, they are generally “S” shaped on their own. These decorative edges have one particular convex hump and a single concave cove (like an “S”) and are typically bracketed by fillets. This instills a more traditional or antique character to your workpiece. Like numerous other router bit varieties, the ogee bit has numerous variants that vary in slope and complexity. For instance, Roman ogee bits typically incorporate much more fillets and stepped ogee bits supply a a lot more gradual (or considerably less steep) profile.
