YUCHENGTECH Mortising Jig 2 In 1
The YUCHENGTECH mortising jig 2 in 1 focuses on versatility with a slotting bracket that acts as an invisible fastener system for router-based mortises and tenons. Note that the slotting bracket needs to be used with a router (not included) and is compatible with 65mm diameter routers from various brands. Important limitations include that it cannot create square slots, and the tool is designed for non-square slot mortising. Specifications show forward/backward stroke of 0–20mm and left/right stroke of 0–50mm, with processable board thickness of 15–50mm.
- Router compatibility: 65mm diameter (router not included)
- Stroke: 0–20mm (F/B), 0–50mm (L/R)
- Board thickness: 15–50mm

Buying Guide
When selecting a mortise and tenon jig, consider the joint size you plan to create, router compatibility, and the level of repeatability you need. Look for adjustable mortise widths and lengths to fit a range of cabinet and furniture components. If your workflow centers on hidden hardware, prioritize jigs that support invisible connectors or faceplates. Durability matters: stainless steel and robust aluminum constructions reduce wear during repeated use.
Router compatibility is a common constraint. Some jigs require specific diameter routers or come with accessories designed for particular brands. If you work with 65mm trimmer routers, verify compatibility and whether router bits or guides are included, as these extras influence upfront cost and setup time. For door installations, jigs that provide template-based templates and magnet-assisted alignment can save time and improve consistency across multiple doors.
Accessibility and support matter as well. Kits with clear instructions, included bits, and a wide array of templates or connectors help reduce setup errors. Consider how easy it is to replace worn components, such as router bits or adapters, and whether the tool supports both gluing and locking joints. Finally, weigh the total package: a feature-rich jig that includes a full accessory set may justify a higher price tag if it dramatically reduces project turnaround time.
