Question about Singer Heavy Duty 6335M

The Singer Heavy Duty 6335M is well suited for sewing thicker materials such as leather, as it has a powerful motor and is equipped with a non-stick gliding foot that makes it easier to feed heavy fabrics. However, the machine may be less suitable for very fine work as it is fast and the speed can only be regulated using the foot pedal. However, it could work well for thicker leather as long as the needle is selected appropriately.
