Still Struggling with Messy Door Lock Holes?
Hand-cutting lock slots can lead to uneven edges, poor alignment, and extra sanding.
Our Solution:
Uses vertical guides with height and depth stops to help control the cutting area and reduce over-cutting.
Many door lock tools only work with one type of power tool, limiting how you can use them.
Our Solution:
Comes with an M10 thread angle grinder drilling rod and a hand drill adapter, so it can work with both an angle grinder and an electric drill.
Ordinary cutters can dull quickly and leave rough slot edges on wood boards.
Our Solution:
Includes 18 mm, 22 mm, and 24 mm tungsten carbide cutters for sharper, smoother, and cleaner slotting.
Some tools are difficult for beginners and require complicated setup before use.
Our Solution:
Designed to be easy to understand and simple to install, making it suitable for professional carpenters and new learners.
