I usually insert a wooden dowel inside the hole of the hose that is close to the diameter of the hole, not to tight but not too loose, a little white grease helps. This keeps the shape of the hose intact. Electrical tape on the outside, cut using the method of your choice, Dremel is my favorite. After the cut is made take an air hose and blow out what’s left of the dowel. WARNING: what’s left of the dowel in the hose is a projectile!
Obviously if you want to make a cut in the middle of a 12 foot hose this doesn’t work but it works great to clean up your previous cuts.
Good luck
