Plywood is generally produced in large, oversized sheets that need to be cut down to size. When using a circular saw it can be difficult to make a perfectly straight cut all the way across, normally the cut ends up skewed. Also when using a table saw it can become dangerous, because the sheet could way up to 100 lbs. and the table may not be large enough to support it. The safest and most precise way to cut plywood and other sheet material is with a quality panel saw. They are available in both powerful, full featured horizontal models, and space saving and affordable vertical models. Panel Saws are just one of the many categories of Woodworking Machinery offered at Tools-Plus.com.
