Precise door lock installations!

This very nice jig set helps me not make any alignment errors when drilling proper holes for the lock mechanism. It has the necessary depth setting collar and tungsten carbide bit to drill a perfectly even hole in from the door edge. It is a very good value and ideal for DIY remodelers and contractors. –David

Why Buy the Door Lock Hole Opener Kit? 

✅ Door Lock Opening: The main purpose of the Door Lock Hole Opener Kit is to facilitate the installation and modification of door locks, specifically designed for tasks such as opening new lock holes, modifying existing eccentric lock holes, and changing password or fingerprint locks on doors. This is engineered for ease of use, allowing users to perform the task with minimal manual effort compared to traditional manual methods.

✅ Precise cutting: Features a split-type drilling machine, which is easy to install and disassemble. Equipped with an industrial-grade linear bearing and a precise scale to enhance cutting precision, speed, and work efficiency. Also includes vertical guides with height and depth stops to prevent overrun cutting. Can be used on wooden and aluminum doors with a thickness of 5.3"/13.5 cm.

✅ Inclusions: Comes with three high-quality tungsten steel cutters, sizes 18/22/24 mm (0.7/0.87/0.95 inch), promising a faster delivery compared to similar products. The kit also includes a metal bracket, a drilling rig, three tool heads, wrenches, rulers, and a woodworking chisel. A total weight of 11 lbs (5 kg), for a more manageable and transportable handling.


  1. Remove the locating ring and set it aside. Then, take the knife stick off the bracket.
  2. Place the knife rod stand on the slide rail workbench and secure it by adjusting the screws.
  3. Turn the drill handle of the knife bar inwards, pierce through the base cloth of the bracket, and fix the trap.
  4. Take out the lock core, mark the height and position of the keyhole on the door where the lock will be installed.
  5. Install the assembled slotting machine on the door, align the knife head with the marked positions of the lock core, and adjust the positioning screw to confirm the working area of the knife bar.
  6. Mark the lock core's depth on the back of the cutter and fix the positioning ring with a hexagon wrench.
  7. Install the electric drill. Hold the tool holder with your left hand and the power tool with your right. Push the tool at a constant speed, drilling to a certain depth before slowly moving out, then move the tool up at a constant speed with your left hand.
