Flush-Trim Router Bits as the name suggests, these bits are used to trim the edge of one material flush with the edge of another– for example, trimming a veneered surface flush with a substrate or using a pattern to create multiple identical pieces. These bits are also used to cut out pattern templates.
How do you guide a router through a cut?
You have a few options when it comes to guiding the router through the cut. You can use a piloted flush trim bit; you can use an un-piloted straight or spiral bit along with a straightedge to guide the edge of the router; or you can use a guide bushing along with an unpiloted bit.
What are flush trim Rouer bits used for?
Flush trim rouer bits as the name suggests, these bits are used to trim the edge of one material flush with the edge of another– for example, trimming a veneered surface flush with a substrate or using a pattern to create multiple identical pieces. They usually are guided by a pilot bearing that’s the same diameter as the cutter.
Where can I get a pattern bit for my router?
I also do a quick demo using a pattern bit (a variation of the flush trim bit). This video accompanies an article what was published in Popular Woodworking Magazine called “Get the Most From Your Router”. You can download that here! And if you are interested in that big fat pattern bit, you can get those in William Ng’s Store.
How do I use an un-piloted router bit?
With an un-piloted bit, you’ll have to guide the router itself along a straightedge, which means that you’ll have to factor in the distance from the edge of the router base to the edge of the bit. Doing so works just fine, but does take a little longer and gives you more of an opportunity to make an error.
When should I use flush trim on router?

Is a flush trim bit the same as a straight bit?
5. Flush Trim. Flush trim bits are essentially straight bits with a pilot bearing that's the same diameter as the flutes. The bearing at the tip guides the cutting arm perfectly around the edge of a surface, allowing you to trim overhanging material perfectly flush.
Can you plunge a flush trim router bit?

Why do flush trim router bits come in different sizes?
Larger diameter bits have a faster cutting speed at the edge, and they can make chipping a problem on brittle materials. Smaller bits cut slower, chip less and can go into smaller interior corners. They get hotter though, due to the smaller diameter.

What is the best router bit for cutting plywood?
In delicate veneered plywood that tends to chip and tear, a down-cut router bit will simply produce the best possible cut without risk of lifting those veneers toward the surface and causing tearout. The 6mm and 12mm diameter router bits in the 00-855 set are an excellent fit for most undersized 1/4" and 1/2" plywood.

What's the difference between a plunge router and a regular router?
However, there's a distinct difference between plunge routers and fixed-base models. Rather than a set base, a plunge router has spring-loaded arms that lift the motor and bit up off the workpiece. To route the wood, the router must be pushed down into the material.
How can I make my router deeper?
Control the cut depth by changing your bit height. Make sure it only cuts a little at a time. The rotation of the bit pulls the router tight against the fence. Adjust the bit to cut a little deeper after each pass.

What are router bits?
Straight router bits are a workshop staple, these bits make cuts straight into a material to form a groove or dado (a groove across the wood grain) or to hollow out an area for a mortise or inlay. They come in a variety of diameters and lengths.
What are the bits used in routers?
Other specialized bits include dovetail bits, drawer-lock bits, finger-joint bits and lock-miter bits.
What are Rockler router bits made of?
Here at Rockler, we offer our own line of router bits designed for the serious woodworker. Rockler bits are made with high-quality ISO K10 and K20 carbide and are sharpened with 600-800 diamond abrasives. They also are precision-balanced and geometrically designed for superior chip ejection.
What size router bits are used?
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" shank bits. Whenever possible, use bits with 1/2" shanks.
What is a rabbet router?
Rabbeting router bits are guided by a spinning pilot bearing at the tip, these bits are designed specifically to cut a rabbet (shoulder) in the edge of a workpiece often used to join pieces. They can be purchased in a set that includes bearings of different diameters, allowing a single bit to produce rabbets of different sizes.
What are edge forming bits used for?
Edge forming router bits are most often used to cut decorative edges. For example, Round-Over bits cut a rounded edge of a particular radius (such as 1/8" or 1/4"); Ogee bits cut variations of an S-shaped profile; Edge-beading bits cut a quarter- or half-circle profile (called a bead); Cove bits cut a concave quarter-circle. Many edge-forming bits include a pilot bearing. In most cases, these bits are used for final decoration of a project where edges have already been established and can serve as guides.
Why are anti-kickback bits important?
These anti-kickback bits have more body mass, and their enlarged bodies prevent the bits from biting too deeply and catching on the material. The greater body mass also helps to dissipate heat and keep the bits sharp longer.
What is an up cut bit?
Up-cut bits, on the other hand, tend to leave a cleaner edge on the bottom of the material. They also have the effect of drawing the chips and dust upwards, and because of that are especially suited for plunging out mortises. Also worth mention are bits that perform both the up-cut and down-cut function in a single swath. Double compression bits are arranged so that they have both an up-cut and down-cut configuration – the two meeting in the middle of the bit. They are designed, as is easily guessed, to provide the cleanest possible edge on both top and bottom surfaces of the material.
What is a down shear bit?
Shear and spiral bits behave differently depending on whether they have an “up-cut” or a “down-cut” configuration. The down-shear piloted flush trim bit you see on the left helps limit splintering on the top surface of the material. A down-shear bit also has a tendency to pull the base of the router downward toward the material, which turns out to be a "feature” when you're using a handheld router to make trim cuts along a pattern or straightedge: it makes it easier to keep the base of the router flat on the surface of the workpiece.
What does it mean when a router is unpiloted?
With an un-piloted bit, you’ll have to guide the router itself along a straightedge, which means that you’ll have to factor in the distance from the edge of the router base to the edge of the bit. Doing so works just fine, but does take a little longer and gives you more of an opportunity to make an error.
What is a shear and spiral bit?
In general, shear and spiral bits cut the surface of the stock with a slicing motion instead of chopping straight into the stock. The result is less energy consumption, less vibration and a cleaner cut. Shear and spiral bits behave differently depending on whether they have an “up-cut” or a “down-cut” configuration.
Can you use a piloted straight edge bit on a router?
You have a few options when it comes to guiding the router through the cut. You can use a piloted flush trim bit; you can use an un-piloted straight or spiral bit along with a straightedge to guide the edge of the router; or you can use a guide bushing along with an unpiloted bit. (Keep in mind, though, that the Edge Routing Dust Port attaches to the bit opening and thereby eliminates the guide bushing method.)

Do you use flush trim on box joints?
Great video, I’m a big fan of flush trim and pattern bits I pretty much use them on every box I have made. Doing dovetails and box joints they are great to clean up the excess on the joints.

How thick should a router board be?
In addition to these tools, you’ll also need a good board to use as a straight edge. 1/2″ or 3/4″ thick works great here. I prefer using sheet material as it needs to be wide enough so once it’s all clamped, you still have room for half your router base to ride on.
Is a table saw good for jointing?
And while the table saw gets the edge really close to perfect, and in many cases it is good enough, sometimes it needs just a little jointing to finish up.
