Structured tooth carbide burs are a good choice for fast roughing out and general carving. Because these have non-directional cutting teeth, they are the best choice for left handed carvers.
About Carving Burs: Which type is right for you and your project?
Most burs that are included in a typical rotary tool kit are intended for general household use, and many are unsuitable for gourd carving. The descriptions below will help you to choose the appropriate burs, you can also find more in depth descriptions on pages 29-31 of my "Gourds" book.
Note: I have been carving wood and gourds for over 30 years. All of the burs shown below are pieces I have used and tested myself.
High Speed Steel Burs
These burs are the mainstays of most gourd carvers. They are inexpensive and come in a wide variety of shapes and sizes. This type of bur cuts with sharpened cutting flutes or "teeth". They will cut aggressively and are perfect for most people that want to do general gourd carving, and their price makes them the best choice for beginners. For most carvers, three basic shapes are adequate (although you may want to add a variety of sizes within those shapes.) I recommend a wheel, a ball, and a either a cylinder or an inverted cone. You can use other shapes as well, but if you are starting from scratch this is a good place to start. These burs will dull after years of use or if misused, but usually a thorough cleaning will extend their life. (More on cleaning burs at the bottom of the page.)
Carbide burs are more expensive than steel burs, but with ordinary care they will outlast a steel bur and should rarely need to be replaced.
Some carbide burs look exactly like steel burs, but will stay sharper much longer. Personally, I don't buy this type as they are much more expensive and the high speed steel cutters last quite a long time when they are kept clean and used only on gourds.
Some burs have bits of tungsten carbide grit fused onto a steel based cutting surface. This type of bur comes in various shapes and cutting grits, but is less aggressive and smoother cutting than a structured tooth bur.
Structured tooth cabide burs have sharp hair-like projections protruding from all sides of the bur. They are great for left handed carvers as they are not directional and are not used with a mandrel. They come in a variety of shapes and grits and are the most aggressive burs for fast carving.
Diamond burs are not intended for carving through the gourd skin. They are better suited for detail carving or sanding operations. These burs are the least aggressive of all but are perfect for sanding or texturizing after the rough carving is finished. Inexpensive kits with several burs will give you plenty of shapes to choose from.
High Speed Steel and Carbide Burs
1/8" Pointed Bur $13.50
Mini Cutting Wheel$16.50
These tungsten carbide burs made by Dura Grit are nice additions to round out a set of carving burs. These are a few specialty shapes that I have personally selected. In general, they are less aggresive than the structured tooth carbides and work well for shaping and smoothing when a smoother texture is desired. The larger wheels work well for removing large amounts of material.
The small pointed bur can be drug to create lines, to undercut relief carving, and works great for cutting channels for heishi inlay, or for drilling and shaping decorative holes. The finest grit works well for filigree type hole piercing.
The 1 1/4" wide shaping wheel is used for "skinning" the gourd, shaping, and removing large areas. DO NOT USE WITH TOOL IN REVERSE.
The mini cutting wheel is perfect for left handed carvers! It operates equally as well in forward and reverse. Head is 5mm wide.
Use the Inverted Cone shape for cutting basketry, ripples, or anywhere a clean, sharp edge is required. 3/8" wide cutting head.

Bur Cleaning Info and Tips
There are different reasons why burs leave burn marks or don't cut well. If you know your bur is relatively new and not likely to be dull, then the cause is often a dirty or clogged bur.
The easiest way to clean all types of burs is to get a small jar (baby food size is fine) and fill it with enough acetone to cover the bur cutting heads. Let the burs soak for a while, the acetone won't hurt them. This will loosen the resins that are clogging the cutting surfaces. After the burs are removed from the acetone, simply scrub them off with a toothbrush shaped brass brush. This should eliminate the majority of the debris. You can resubmerge and repeat if necessary.
Carbide burs are much tougher and in a pinch they can even be flamed with a small propane torch to burn off the residue. Use caution when using this method; flame the bur while it is chucked into your tool, don't attempt to hold it with pliers (or your fingers!!!). Do NOT try this on steel burs. They will lose their temper and will not hold a sharp edge. If you are cleaning a mandrel mounted carbide bur, you must remove the small fiber washer before using the torch cleaning method.

Note: Large or heavy headed carbide burs will work better at slightly lower speeds. They can be run at full speed in a Foredom tool, which runs slower than other tools. Practice with them to deterimine the ideal speed for your own tool. Always insert these burs completely up to the shoulder depth (the thick area of the mandrel) when mounting into the collet or chuck. Do not run the mandrel mounted burs in reverse.

Below: Saburr Tooth brand structured tooth burs are my favorite carving burs because they have fast cutting teeth to remove a lot of material quickly. All of these burs have a 1/8" shaft.
The dovetail shape is good for cutting basketry and ripples, the taper shape works well in tight areas, and also gives you the proper angle for flattening backgrounds, and the large head cylinder is perfect for smooth, even inlay channels. The long taper shape is excellent for getting into small areas, or use the bud for small areas or lay on its side for wider cutting areas. The ball is good for general fast removal, while the ball nose is a nice combination shape with the advantages of both a cylinder and a ball.
Safe end burs have no teeth on the top end of the bur, are perfect for cutting along borders - because there are no teeth on the end, you get a really clean cut.
