Stainless steel scales align mortise length within precise crosshairs, aiding accurate layout and repeatable cuts. It fits square, round, and irregular stock, making it versatile for table projects.
Features emphasize precision and adaptability: a complete jig package, versatile mortise lengths and widths, and integrated guides for repeatable results. This option is well-suited for shop setups that rely on a router as the primary mortising tool, particularly when consistent, tight joints are critical to table integrity.
O’SKOOL Mortise and Tenon Jig

The O’SKOOL Mortise and Tenon Jig is geared toward cabinets, chairs, and table construction using a plunge router. This kit includes the mortise and tenon jig assembly, a 1/4-inch router bit, and bushings for 1/4″, 3/8″, and 1/2″ tenons. A lock nut with a mounting adapter, self-adhesive sandpaper, and a 2.5mm hex wrench accompany the package. The jig enables fully aligned mortises and tenons ranging from 3/4″ to 3-1/8″ long and 1/4″, 3/8″, or 1/2″ wide, with stock thickness from 1/2″ to 1-1/2″ and beyond 2″. It promises consistent dimensions and secure joints when gluing or fastening with hardware.
Use this jig when precise alignment across multiple joints is needed, particularly in cabinetry and table components where repeated mortises are required. The included guides simplify setup, and the range of tenon widths offers compatibility with various stock profiles.
Mortising Machine Attachments (BMTURNING)

The BMTURNING Mortising Attachment converts a drill press into a mortising tool. It includes a locator, press block, side positioning rod, fixed seat, and other accessories, along with four mortise chisel sizes (1/4″, 3/8″, 1/2″, and 5/8″). The product emphasizes high-quality steel bits designed to minimize clogging from sawdust, delivering fast cutting and durable performance. Important installation notes specify collar diameter compatibility and a minimum vertical distance between the chuck and workbench, ensuring safe and effective operation. This option suits shop setups that already own a drill press and want to add robust mortising capability.
Consider this attachment when upgrading an existing drill press without investing in a full dedicated mortising machine. The included chisel sizes cover a broad range of mortise dimensions, making it a flexible addition for various table joints and joinery tasks.

Buying Guide: Key Purchase Considerations
- Tool type and project scope: Router-based jig sets excel for loose-tenon joins and repeatable mortises, while drill-press attachments offer conversion flexibility for existing machines.
- Stock dimensions and tolerance: Check the maximum mortise length, width, and compatible stock thickness to ensure the jig matches your typical table dimensions.
- Precision and repeatability: Look for features like built-in scales, alignment guides, and durable construction (steel, stainless, or cast iron) to minimize drift.
- Versatility: Some jigs support multiple tenon sizes, various stock shapes, and adjustable angles—these options save time on complex table joints.
- Installation and compatibility: Review collar diameters, chuck-to-bench distances, and compatibility with your plunge router or drill press to avoid fit issues.
- Storage and portability: Jigs with included storage for chisels and accessories reduce clutter and improve workflow in smaller shops.
- Safety and setup time: Tools that offer straightforward setup and clear instructions reduce miscuts and improve safety when handling sharp chisels.
- Cost vs. value: Compare the complete jig packages with individual attachments to determine which setup delivers the best return for your typical table-work load.
- Maintenance: Consider the availability of spare bits and replacement parts, as well as ease of cleaning sawdust from joints and chisel slots.
Choosing the right mortise and tenon solution depends on your workflow, whether you prioritize quick setup, maximum precision, or the ability to tackle a range of stock sizes. For table builds, a combination of a high-precision router jig and a reliable drill-press attachment can cover most joinery needs, ensuring durable, accurate joints across legs, rails, and tabletops.
