The mortising router bit is designed to make shallow cuts or shallow pockets. Whiteside's mortising bits feature a short down shear flute for an improved top edge finish. An ideal option for hinge mortising, dados and milling the ‘shoulder’ and ‘cheek’ of tenons. The additional width and depth of the gullet improves chip clearance. Please peruse Whiteside’s “Screw Type Helix Mortise” bits for additional mortising options. Suitable for CNC, table mounted routers and hand held routing. Whiteside’s cutting tips are hand brazed, precision ground and made from industrial grade micro grain tung. Router Bits vs. Shaper Cutters. Router vs. Shaper: Cousins with Different Functions. Often enough many small shops have to make do with the space they have. When it comes to balance space, time, and money, many times the shaper becomes victim of being left out. Like the beading bit, some chamfer router bits will also have a bearing tip that can ride along the edge of the workpiece. Carbide Tipped Bit. Straight carbide-tipped bits are what make your router one of the most versatile tools in the workshop. And they are also one of the types you will use the most. These bits will be for cutting square bottomed straight grooves, and they will come in various diameters and lengths. The most common and useful ones are 1/4, 1/2, and 3/4 diameter bits. The straight carbide tipped bit will be useful for cutting dadoes, rabbets, and grooves in plywood when   1 hinge mortising bit. 1-panel pilot bit. 1 round nose bit.

Home Articles Spiral Router Bits vs. Straight Router Bits. Because a spiral bit is designed much like a drill bit, it makes plunge cuts easily. The increasingly popular spiral router bits borrow technology from the metalworking industry. Spiral bits look like drill bits and are most often made of solid carbide, so they are super sharp and leave a superior cut on wood. Two flutes ground around the body of a mortiding bit smooth vibration by spreading the cutting action mortising vs straight router bit year a longer edge.

With their drill-like point, spiral bits are also better for plunge-cutting. The new solid-carbide spiral bits come with some disadvantages. The first is that the cutters are expensive. But because most spiral bits are ground on the tip end of the flute, somewhat like a drill, you can plunge straight down as far as you like, without stopping. On most straight bits there is a space above the web, between the cutters, where no cutting takes place during a routr plunge because there is no cutter overlap.

Chuck a straight bit into your drill press and plunge it into a piece of wood. To go any farther, the bit has to abrade the wood away mortising vs straight router bit year this middle area.

You just have to sweep the router while you are plunging. Solid-carbide spiral bits are becoming increasingly popular because they make a yeaar clean cut. But they have many limitations compared to the straight bits that have been popular for years.

All spiral bits make clean cuts. This veneered mortising vs straight router bit year shows the effects of the three types of spiral bits on mortisinng top and bottom edges.

The three basic cutter configurations for spiral bits are up-cut, down-cut, and a morrising of the two, known as a compression bit. A down-cut touter sends the straigght downward; an up-cut bit sends them up to ward the shank. On a router table, all direc-tions are reversed. Besides mortising vs straight router bit year the chips, the advantages of these configurations are best illustrated by the quality of cut, especially on bt plywood see the photos above. A down-cut bit will leave a clean edge on top but a ragged straiight on the bottom; an up-cut bit will accomplish the opposite.

This is great until you want to cut a mortising vs straight router bit year with no tearout on the face. A down-cut bit will leave a clean top edge, but it sends the chips downward, into the dado where they have no place to go. You can make this cut, but you have to take it slower than usual to give the chips a chance to clear. For woodworkers who work with A-grade veneers on both sides of the stock and ruoter have a clean edge top, bottom, and middle, the compression mortisinv is a good choice.

It has an up-cut configuration on the tip of the bit and a down-cut spiral ground on the shank. By lining up the bit just right, you can get a superior edge across the entire thickness of the wood. Router-bit manufacturers have difficulty making solid-carbide spiral bits with cutting diameters larger than their shanks. Straight bits, on the other hand, go through dozens of fractional sizes, all the way up to 2-in. Depending on the job you have in mind for your router bit, straight bits also come in a variety of cutter lengths.

So you can buy close to exactly the length of cutter you need. Straight bits also have a huge advantage over spiral bits when it comes to template routing, because you can buy them with guide bearings. And those bearings can be mounted on the tip of the cutter rrouter on the shank of the cutter, depending on your needs and your template. The bearings are made for a variety of cutter diameters and lengths. With their superior edge cut, spirals mortisnig great template cutters when used with collar guides.

But when it comes to bearing-guided bits, spirals seem to be available only with bearings mortisint on the end of Mortising Vs Straight Router Bit Up the bit. Shank-shod, bearing-guided, solid-carbide bits spiral bits with the bearings on the shaft end of the bitwhich would permit template routing with the template on top of the work and trim cutting through only part of the work face, are not available.

Some royter like to sharpen their straight bits, although Routsr find it difficult to get it right and always send out my bits for sharpening. Carbide-tipped straight bits usually have enough carbide thickness to be reground four or five times, and the tech- nology to do so is mortising vs straight router bit year. A few services claim to be able to sharpen spiral bits.

To me, this translates into a substantial loss. Spiral bits might stay sharp longer than straight bits, but even so, the cost of using rouer bits will always be higher. Spiral bits work incredibly well in the production environment and especially in CNC computer numerically controlled router industrial applications. But in a hand router, their use sometimes imposes unusual risks not mortlsing with the equivalent or bigger straight bits.

The down-cut spiral bit's screw-driven forces are sufficient enough to pick the router up and twist it out of your hands—with no warning. I know, because it has happened to me. On end grain the spiral bit is getting even more traction, so the risk mortjsing even greater—a pity, too, because a sweet end-grain finish is attractive. The up-cut spiral bit can have the opposite effect. It wants to pick up the work. So you must secure the work in some kind of fixture or hold it by a clamp. I never rout anything that is not secured mortising vs straight router Mortising Vs Straight Router Bit Sound bit year clamped, but some people do.

I do keep a few solid-carbide spiral bits because, when I want a beautiful face cut or I am cutting rouuter mortises, and I have the money, there is just nothing better.

But my cabinet is mostly full of a wide variety of straight bits. For general-purpose work, for template and pattern routing, and Mortising Vs Straight Router Bit Yet for those times when need a large-diameter bit, I still reach for one of my straight bits.

Parts of a Straight Bit Fluted Double fluted straight bits are likely the most widely used router bit on the market. These bits have two flutes (arms), with a carbide blank brazed (joined) onto each flute. Double fluted bits give a very smooth finish. They excel in routing grooves, dados, rabbets, mortises and tenons. Jun 26,  · A dado is a Straight (e.g. in a line) groove, you cut it with a straight (refering to the edge of the bit profile) bit when using a router. Most bits are called by their profile, But the exception is if they phelpo make a unique joint then they are named buy the joint they make. Router Bit Shanks. The router bit shank is the solid, cylindrical part of a router bit. It's the part of the bit that goes into the collet of the router. There are two common sizes of router bit shanks: 1/4" and 1/2". Many routers come with interchangeable 1/4" and 1/2" collets so that either size bit can be used, but some accept only 1/4.
