1. Main Function: The door latch can not only replicate the shape of the latch on the door, but also dig out the door lock hole through the top chisel and install the door latch with the built in driver drill bit.
2. Multiple Shaped Blades: The built in latch installation kit features switchable square or circular blades and a top chisel, which helps cut professional latch shapes and lock holes.
3. Sturdy Structure: The two hole openers are made of carbon steel, and the guide template is made of reinforced plastic, with a long service life.
4. Accurate Drilling: The adjustable guide template facilitates accurate drilling and is equipped with a spring lock arm for selecting door width and door frame height. Drill vertically on one side of the door panel until halfway through, then drill on the other side of the door panel until fully penetrated.
5. Widely Applicable: This design is suitable for the most common sizes of wooden door locks in daily use. Adjustable plastic guide plates are suitable for doors with thicknesses of 1 3/8 inches, 1 1/2 inches, and 1 3/4 inches, as well as door frames with thicknesses of 2 3/8 inches and 2 3/4 inches.
