Description
Door Lock Installation Kit with Mortising Jig and Hole Cutters, Woodworking Tools
-
Cuts stay inside the lines: vertical guides with height and depth stops avoid overrunning the cutting area
-
Works with the tool you own: an M10 thread rod and an adapter for a hand drill suit an angle grinder or an electric drill
-
Quick, smooth slotting: three tungsten carbide cutters with a sharp edge give a smooth slotting shape
-
Easy for first-timers: simple to understand and easy to use for professional carpenters or new learners
-
Boards beyond door locks: it also works for other regular wood boards
Opening, slotting or modifying a door lock hole is easier when the cutter cannot run past the cutting area. This door lock mortising jig uses vertical guides with height and depth stops, and it is simple to understand and easy to use for professional carpenters and new learners alike. Complete accessories are included in this package; the angle grinder or electric hand drill is not included.

Three different hole cutters (18/22/24 mm) in high hardness tungsten carbide steel give quick slotting with a sharp edge and a smooth, beautiful slotting shape. The M10 thread angle grinder drilling rod and an adapter for a hand drill let this woodworking jig work as an angle grinder attachment or with an electric drill, so one set of door installation tools covers both. The cutters are sharp, so handle them with care and keep fingers clear of the cutting area.
