Door Latch Mortise Tool – Fast, Precise Latch Plate Cutting Jig
Make Professional-Grade Latch Mortises in Minutes – No Guesswork, No Mess
🔧 Precise Latch Replication in One Tool
This latch mortise tool is engineered to accurately copy the exact shape of your latch plate every time. The integrated scoring head outlines the latch, while the top chisel cleans out the mortise for a snug, professional fit. Built-in driver bit storage keeps your screwdriver bits close at hand so you can cut, chisel, and install the latch with a single tool—eliminating crooked plates, loose latches, and unsightly gaps.

🛠 Robust Plastic Construction & Job-Site Ready
Made from high-strength engineering plastic, this door lock installation tool withstands repeated hammer blows without cracking or warping. Its compact, lightweight body fits easily into a tool bag or belt, making it ideal for carpenters, installers, and DIY homeowners who need a reliable latch mortiser they can carry from job to job.

📐 Switchable Square & Round Blades
Two interchangeable scoring blades—one for round-corner strike plates and one for square—let you match the exact latch style used on your door hardware. The adjustable 90° fence sets the correct backset and supports both 1-3/8 inch and 1-3/4 inch thick doors, giving you the flexibility to work on interior, bedroom, and entry doors with a single tool.

⏱️ Time-Saving, User-Friendly Setup
With combined scoring and chiseling functions, latch mortising takes just a few quick strikes of a hammer. The reversible scoring head handles both square and round plates, reducing tool changes and simplifying your workflow. Even first-time users can create clean, repeatable mortises in minutes by following the included illustrated instructions.

🚪 Fits Most Standard Door Latches
Designed to work with the majority of residential door latches, this mortise jig aligns easily over the pre-bored latch hole to keep everything square and centered. Accuracy-guided scoring protects the door surface from slips and over-cuts, helping you achieve clean edges and a tight-fitting latch plate with minimal sanding or touch-up.

❓ FAQ
1. What type of doors can this latch mortise tool be used on?
This tool is designed primarily for wooden doors, including solid core and hollow core interior doors. It can also be used on some composite doors, but it is not recommended for metal or steel doors, as the scoring blades and chisel are optimized for wood.
2. Does it work with both round and square latch plates?
Yes. The kit includes interchangeable round and square scoring blades. Simply choose the plate style that matches your latch hardware, install it in the scoring head, and you’ll get a perfect outline for either round-corner or square-corner latch plates.
3. Do I need power tools to use this mortise jig?
No power tools are required to cut the latch mortise itself—just a hammer to tap the scoring and chisel sections. However, you will still need a drill (or existing pre-bored hole) for the latch hole in the edge of the door before using the jig.
4. Is the tool suitable for both left-hand and right-hand doors?
Yes. The reversible fence and centered guide design allow the mortise tool to be used on either left-hand or right-hand doors without additional adjustments. Simply position it flush to the door edge and follow the instructions.
5. I am a beginner—can I still get professional results?
Absolutely. The included instruction sheet illustrates each step, and the built-in guides help you keep the tool square and aligned. Take your time, strike evenly with the hammer, and you’ll achieve clean, professional-looking latch mortises even on your first project.
