Deckel is making a simple drill sharpening attachment(for $950!) to the SO and SOE tool grinder. This is grinding the tip in a conventional way, but in fact the SO and SOE can do a much better job without any accessories. Drills 1mm - 19mm can be easily sharpened with the superior split point.
The only requirement is a a set of collets in each size of the drill. I have a full set of Deckel collets in both inch and metric that I share with my FP1, and for smaller and in between sizes I am using a ER holder that fits in the 12mm Deckel collet.
The procedure is simple.
1. Lock the drill in a collet and set the flutes horizontally. I line it up visually against a straight edge on a surface plate.
2. Mount the index head on the grinder and set the horizontal plane (#1 in the photo) angle to the angle of the drill(let say 59 degrees for 118 point)
3. Set the vertical plane angle (#2) to the first cutting angle, for example 8 degrees)
4. Grind both lips (rotate the index 180 degrees)
5. Set the vertical angle to the secondary angle (for example 12 degrees)and cut the two faces.
