Most .25 " compression cutters seem to feature a 1" cut length...I actually had the opposite problem than you there...I couldn't readily get one that exceeded 1.25" without going to a larger diameter so I was right at the limit for cutting 1.25" exterior MDF.

Right but even with a 1/4" dia compression your up cut on the tip is usually 1/2" or more. So with 1/4" material there is no sense in spending the money on the rest of the "compression" portion thats never going to see a single wood fiber.
