Features Red Laser 650 nm, 1.6mW (Laser Class 2M). DXT - Deep and Exact Cutting Technology. Deep cutting - 3 stage reduction gear unit and movable rear blade guard provide larger capacities of cutting crown molding or skirting board. Capable of diagonal cutting up to 203mm in crown molding. Capable of vertical cutting up to 165mm in baseboard (skirting). Exact cutting is obtained by using 4 short poles instead of the usual 2 longer poles. This also reduces vibration and makes for more precise cutting. 6 linear ball bearings are used to support the 4 poles for smooth and precise sliding out. Double sliding guide fence - the upper and the lower sections slide independently for added convenience; each upper fence slides outwards for bevel cut and each lower fence slides inwards to securely hold small workpieces for precise and exact cutting. Quick and accurate mitre angle lock - mitre angle can be locked or unlocked by simply turning the handle 90°. Positive stops at 0°, 15°, 22.5°, 31.6° and 45°.
