  • Publication number: 20130269494
    Abstract: A miter saw with a cutting alignment device includes a base with a work surface provided thereon. A bevel support is pivotable with respect to the base and a cutting blade is supported by the bevel support. A dust chute is adjustably secured to the bevel support and pivots with respect to the base when the bevel support pivots. The dust chute includes mounts that allow lateral adjustment of the dust chute with respect to the bevel support. A laser alignment device is positioned on the dust chute and configured to emit a beam of light toward the work surface. The dust chute includes a receptacle designed and dimensioned to releasably hold the laser alignment device. Because the laser alignment device is retained on the dust chute, adjustment of the dust chute also results in adjustment of a beam of light emitted from the laser alignment device.
