Lasers add a tremendous visual aid to positioning the lumber in alignment with the blade. Of course the big question is, how well does the blade and the laser align with each other. The angle and horizontal position of the Laserkerf can both be adjusted to bring the laser beam in exact alignment with your saw blade. Most lasers mark only one side of the blade and are not adjustable.

Some lasers, that are adjustable, must be aligned each time you switch sides of your blade. The Laserkerf, with its blade matching width, requires no alignment during the cutting operation to switch from cutting on one side of the blade to cutting on the other. One blade mounted lasers instruction tells the owner to cut 50 pieces of wood to become accurate with the cut verses the laser line.

The photos below show cuts made on a mark using the Laserkerf laser beam for alignment.

The left and center cuts split the mark and the cut on the right is at the edge of the mark.

The Laserkerf is unique in the way it marks the cut area.

The normal laser line is approximately .030". in width . The Laserkerf standard laser beam is .125" wide . You can see the dramatic difference. The standard carbide saw blade cuts a kerf .125" wide. It is easy to see that when the laser is aligned with the blade everything in red will be removed. The two pictures below show the cut marks as they would be used in alignment with the laser/blade.

No matter which side of the blade the good section of the wood needs to be on makes no difference because the laser beam shows the material the blade will remove.
