Drill Bits

Straight Cutting on Goose Eggs

The No. 11 is the recommended disc for straight cutting, however some eggcrafters prefer the BS27E or the BS27D disc. The important thing to remember is to only use these larger discs for straight cuttin, if you try to cut curves with them you will either damage the diamond disc or crack you egg.

Cutting Curves on Goose Eggs

When cutting curves use the smaller diameter discs. For a gentle curve use the BH515A with the split adaptor, but as the curve becomes tighter, you should use the BH515B or BH515C witht he split adaptor. If you prefer burs with a longer shaft use the BS27H.

Filigree Work on a Goose Egg

For filligree work or cutting unusual shapes the BS1B comes into its own. This diamond bur comes to a point, there is not much diamond grit on a point so don't use this bur for making holes in your egg or you will find yourself 'punching" a hole in the egg and breaking it. The rule is to always drill a small pilot hole at the point where you want to start your filigree work. The tungsten carbide bur 129/1 is ideal for this.

Special Burs for Goose Eggs

If you blow your own eggs the diamond bur BS8 is designed to make neat round holes in the end of eggs, using the BS8 you can make the hole small or by continuing make it larger. As with all pointed burs do use the 129/1 to make a starter hole. If your design includes petal or droplet shapes then use one of the 3 sizes of 'Jean Bennett Flying Saucers".

Tools for Air Drills

Because Air Drills go so fast, I prefer to use Tungsten Carbide Tools as they last longer than the diamond types at these high speeds. Most of the time you should be using the Tungsten Filigree Bur 1169L, This is end cutting as well as side cutting now and again. To work in tight corners use the BH48. For straight cutting use the BH515A, BH515B. For Petal or Droplet shapes use the air drill Jean Bennett Flying Saucers, if you blow your own eggs use the FG4 but remember to make a starter hole with your 1169L bur. For Tight Curves the BH515C can be useful.

Cutting Ostrich Eggs

Ostrich Eggs are very thick, difficult to cut and cutting tools can easily overheat. The golden rule is to stop often to clean the egg dust off the burs. For straight cutting use the No 11 disc, for gentle curves use the BS27E. If the curve is too "Sharp" you will damage the disc so change to a smaller disc sich a the BH515A with the split adaptor. For even tighter curves use the BH515B, this disc won't cut all the way through the shell so you will have to follow up with the BS1B. It is slow going and there is no easy easy option. If your design includes petal or droplet shapes use the Jumbo Jean Bennett flying saucer.
