MICRO blades are 15mm x 3mm. Capable of bowls up to about 180mm.

SMALL blades are 20mm x 5mm. Capable of bowls up to about 220mm.

STANDARD blades are 25mm x 6mm. Capable of bowls up to about 350mm.

LARGE blades are 32mm x 6mm. Capable of bowl diameters up to about 450mm.

The reach capacity is somewhat set by the technique used.  Many operators stop short of the core coming free with the lathe running for safety reasons and stop the lathe and lever the last bit of the core out by hand.
