A medium-sized radial arm saw fits a saw blade with a 250 to 260mm diameter. You can often saw deeper and wider than with a small radial arm saw. You can use a 250mm, 254mm, or 260mm radial arm saw for most jobs in and around the house. Does your radial arm saw run on a battery? Then you can get to work anywhere without problems. With an underframe, your medium-sized radial arm saw stands firmly and at a comfortable working height. You can also saw wider workpieces if your radial arm saw has a pull function.
