When using a circular saw, you can adjust the depth of the cut. This prevents the blade from binding and overheating. Most table saws have an adjustable fence and miter for cutting at angles. Carbide-tipped blades are recommended for both circular and table saws. They give clean cuts with less chipping and roughness along the edges.
All saws leave some roughness on cut edges.
Use it to drill holes and, with a screw-bit attachment, to drive screws into wood. All woodworking tools are easier and safer to use when the wood is securely attached to a workbench or sawhorse with clamps. Sturdy and dependable sawhorses, superior to most manufactured ones or those made from kits, are easy to build from lumber you may already have around the workshop. When you custom-build a sawhorse, you can create one with the dimensions and features that best suit your needs. Don't hesitate to experiment with the dimensions and materials.
