Using this tubing cutter is easy. First, place the tube you want to cut inside the cutter. Then, tighten the cutter using the fine - pitch threads, which will give you extra torque. The cutter wheel will smoothly cut through the tube. After cutting, you can use the attached blade reamer to deburr the tube. When using it, make sure the tube is firmly placed to avoid uneven cuts. Keep the cutter clean after use. If the cutter wheel gets dull, you can replace it with a new SXT cutter wheel (Part 42835) that you can buy separately. Since it's made in the USA, you can expect high - quality performance. Store it in a dry place to prevent the zinc - plated body from corroding.
