Circular saws rotate by default in a counter-clockwise direction. The teeth of a circular blade are designed to cut on the upstroke in the forward direction. This pushes the material forward and towards the blade so that it helps maintain control of the saw and the workpiece.Click to see full answer. Just so, which way should saw teeth face?Install the hacksaw blade so the teeth face forward. The saws are designed so the blade will cut when it’s pushed (the forward stroke) rather than when pulled (see photo). Some blades have an arrow that shows the correct installation (the arrow points toward the handle).Also, does a circular saw cut up or down? Because a circular-saw blade cuts on an upward rotation, the bottom face, in which the teeth enter the cut, will almost always have a clean, tear-out-free surface. Meanwhile, the top face suffers tear-out so bad it cannot be used in a visible area on a project. In this way, what causes kickback on a circular saw? Kickback is a fact of life for anybody who uses a circular saw often. It is caused by the timber that is being cut, bending in some way, so that it jams on the back of the blade, making the saw buck or stall.Why does my circular saw not cut straight?If you are struggling with the circular saw to cut straight line on the wood, at first, look at your workpiece. So, if you find out that your saw is okay and the problem is with your unstable wooden piece, just have a set of hold down clamp. It will lay hold on the workpiece with the table to make it stable.
