I bought a Tool and Cutter Grinder for several reasons but the main one was so I could make "Step Drills". I grind the "step" part to diameter on my metal lathe toolpost grinder but I needed an accurate way to grind the relief angles on the cutting edge.
The grinder came with a 5C collet chuck but a 5C is limited as to the diameters it will hold. On the other hand, I already had a full set of ER32 collets that would be perfect for what I needed.
Here are the two chucks side by side, the ER32 on the left and the 5C is on the right...
Here are 3 views of the chuck I made...
Here are two views of the 5C chuck that came with the grinder...
