Door Lock Tool Kit with Milling Cutter for 1-3/8" Doors

【Precise Fit】This door lock mortise jig is designed for standard 1-inch x 2-1/4-inch strike plates, ensuring precise alignment on 1-3/8-inch and 1-3/4-inch thick wooden doors. It works perfectly with rounded plates and right-angled hardware after lightly chiseling the corners, providing a clean, flush fit to the door edge without guesswork. 【Built-in Depth Control】The built-in 1mm, 2mm, and 3mm depth settings make it easy to adjust to the thickness of your strike plate. Combined with the included cutter, this strike plate installation jig helps maintain a consistent milling depth during repeated installations, reducing edge tear-out and preventing uneven plate mounting. [Durable Anodized Aluminum] Made from solid 6061 aluminum alloy with a protective anodized finish, this rigid jig resists bending, warping, and wear on job sites or in the workshop. Its robust construction maintains tight tolerances during multiple door installations, ensuring reliable long-term accuracy. [Complete Accessory Kit] Each mortise jig comes with a dedicated cutter, drill bit, and screwdriver bit to simplify your setup. Having the necessary cutting and fastening tools right out of the box eliminates trips to the hardware store and makes door preparation quick and efficient. [Simplified Operation] Designed specifically for mortising strike plates onto the edge of doors, this strike plate setting tool holds firmly in place, allowing DIYers and carpenters alike to create clean, professional mortises without complex setup. It enables precise replacement or installation of strike plates in minutes, while simplifying routine adjustments to wooden door hardware.
