Spiral Cutter Router Bits are also very well adapted to plunge drilling and routing. In general the word on them is “quick and clean.” A disadvantage is that they are more expensive than regular straight cutter bits, and for technical manufacturing reasons, the heads cannot be made wider than the shaft. So the choice of bit sizes is limited. There are also no ball bearing pilot rings for these bits, but one can use a copy ring to get a similar result if needed. Sharpening these bits should only be done by a professional sharpening shop. The Spiral Cutters by Sistemi Klein are made of solid tun. I have a question about spiral router bits as I have no experience using them. I have a chance to get a couple but with limited funds right now, I only want to get ones that I would use frequently. What type (up/down/compression), what diameter, and what function would you use them. From everything I’ve read it looks like an up-cut bit is used for hand-held routing when doing mortises and a down cut for router table work for dadoes, rabbets grooves. What are your thoughts?  Our production quality solid carbide spiral bits combine effective chip removal with a continuous shearing action cut not obtained from a standard straight bit. You’ll get smoother cutting action with better results. Up-cut Bits provide faster cutting while they pull chips up and out of the work or towards the router. Straight spiral bits are available in either solid high speed steel (HSS) or solid tungsten carbide. Straight fluted bits are more common than straight spiral bits. HSS is formed from molten molybdenum, tungsten and chromium steel. Beginning as a liquid, it has a fine molecular structure capable of achieving and maintaining a very keen edge.  While using some router bits (both straight and non-straight types), you can use a bearing of a different diameter in order to obtain an alternate profile or cut. A good example is a rabbet bit, as the bearing adjusts the amount of material the bit removes with each pass. What’s the angle? While the cutting edge is the “business side” of a router bit, there’s a lot more behind it.
