Spiral Router Bits vs. Spiral Bits Leave a Clean Edge The three basic cutter configurations for spiral bits are up-cut, down-cut, and a combination of the two, known as a compression bit. Straight Bits Come in Many Sizes and Bearing Configurations Router-bit manufacturers have difficulty making solid-carbide spiral bits with cutting diameters larger than their shanks.
Sharpening Spiral Bits Is Difficult, if Not Impossible Some woodworkers like to sharpen their straight bits, although I find it difficult to get it right and always send out my bits for sharpening. Spiral Bits Can Be Risky to Use Spiral bits work incredibly well in the production environment and especially in CNC computer numerically controlled router industrial applications.

If you advance the router in the same direction as the bit's rotation, the router will run along the edge of the workpiece and you'll have to fight to keep control.
When looking straight down at the top of a router, the bit rotates in a clockwise direction. That means you should move the router from left to right, but—and this is important—that's only true when the router is positioned in the middle between you and the workpiece.
For example, if you were routing the edges of a board, you'd move the router from left to right across the edge closest to you. But, when routing the opposite edge, the one farthest away, you'd advance the router from right to left. That's because the workpiece--not the router--is now in the middle. In that position, the router is moving right to left, but it's correctly cutting against the rotation of the bit.
One of the best and safest ways to begin routing is to use router bits fitted with ball-bearing pilots. The bearing rides along the edge of the workpiece, effectively keeping the bit on course and in control. Simply set the depth of cut and you're ready to rout. There's no need to attach an edge guide to the router or straightedge fence to the work.
The bearing alone will ensure the bit cuts to the proper width. Nearly all edge-shaping and trimming bits are available with ball-bearing pilots, including rounding-over, Roman ogee, chamfer, rabbeting, and flush-trimming. Once you've mastered basic routing techniques, create a precise milling machine by equipping your router with a guide bushing and straight-cutting bit. A guide bushing aka template guide is simply a steel collar that mounts onto the router's base.
Protruding from the collar is a short steel tube through which the bit extends. The tube is guided along the edge of a template, allowing you to quickly cut boards to virtually any size or shape. Here's a brief description of how to use a guide bushing:. Start by cutting a template to the desired shape out of plywood, MDF or hardboard.
Also, be sure to sand the template edges perfectly smooth. The bit has two "wings," each equipped with a sharp tungsten-carbide tooth. The slot depth depends on the distance from the ball-bearing pilot to the cutting teeth. Note that some slot-cutting bits have interchangeable pilots of different diameters, allowing you to alter the cutting depth by swapping out the ball-bearing pilot.

Follow up with a secondary drill for the full depth of cut of the workpiece. PCD tooling is manufactured in a high-temperature and high-pressure laboratory that fuses diamond particles onto a carbide substrate, which allows the diamond to be brazed onto a tool body. PCD offers a harder cutting edge providing a higher resistance to wear and quality of finish is often significantly improved.

The cutting implement that can be made to cut aluminum, brass, copper, and other non-ferrous metals, wood, tiles and fiberglass.
Router bits made to cut wood often have steel bodies and carbide tips made from tungsten or titanium combined with carbon. Because router bits can be practically fashioned to serve whatever purpose there is, the types of router bits can be quite varied. Router Bit Sets. Sets specifically designed for a variety CNC machining applications including signmaking, doormaking and general purpose.

Specially designed for working in Metal working Steel Cold roll, soft steels, gummy stainless , Tool steels, exotics like titanium, inconel, PH stainless etc. Entire gambit of "steel". The special carbide grade combined with the AlTiN coating gives amazing performance while the unique corner chamfer gives the bits great strenght.
Manufactured from our exclusive ultra-fine micrograin carbide, these bits feature a 30 degree Center Cutting Mill End and Aluminum Titanium Nitride AlTiN coating for superior cut quality. These multi helix end mills are outstanding tools for peripheral milling, and can take aggressive cuts along the full length of the overall flute length with no issues.
They last much longer than a general purpose end mills, partly because they are coated, partly because they dampen vibration which tends to break a sharp cutting edge down very quickly. Two cutting edges spaced degrees apart, each half the length of its flute. One extends from the tip to the middle to end.
The configuration combines the cutting speed and chip clearance of a single-flute bit with the finish of a double flute bit. Excellent for dense or abrasive man-made materials and panel goods. For high volume, high speed cutting in dense natural woods and abrasive wood composites, use solid carbide bits when routing straight grooves, rabbets, dados, joints, mortises, trimming material or making a general cut.
