Quick answer: which Porter-Cable dovetail jig should you buy?
For most shoppers seeking a new porter cable dovetail jig, the key choice is between a complete bench-mounted jig and a template or replacement part for a jig they already own. Porter-Cable’s well-known 4212 is a complete jig with multiple templates and guides; older models such as the 4210 and 4216 may turn up used, but their included templates differ. Check the exact model and inventory before buying: availability, package contents, and compatible accessories can vary, and a used jig may be missing parts that are costly or difficult to replace.
The 4212 is the most versatile starting point when you want to cut more than one joint style without sourcing templates separately. If you make only one kind of joint, a less-equipped older package—or a compatible replacement template for a jig you already have—may be more economical. Before choosing, compare joint types, stock thickness, template contents, and the bits and guide bushings required for your router.

Porter-Cable models at a glance
The figures below summarize commonly documented specifications for these models. They describe the jig’s stated capacity, not a guarantee that every included template cuts every listed joint at every thickness. Confirm the manual and package contents for the specific unit, especially when buying used or from old stock.
| Model | Typical package and joint options | Stated stock capacity | Buying note |
|---|---|---|---|
| 4210 | Basic package; commonly supplied with a half-blind dovetail template | Up to 1-1/8 in. thick; up to 12 in. wide | Consider only if its template suits your project and the package is complete. |
| 4212 | Expanded kit, commonly including templates for half-blind, through, and sliding dovetails, plus box-joint capability | Up to 1-1/8 in. thick; up to 12 in. wide | Best fit for varied work; verify the precise template and accessory list before purchase. |
| 4216 | Multiple-template package; commonly listed with half-blind, through, and box-joint options | Up to 1-1/8 in. thick; up to 12 in. wide | Used listings can be worthwhile, but confirm exactly which templates and guides are included. |
These are fixed-template jigs: the template determines the joint pattern, while the router, bit, guide bushing, and setup determine the cut. “Up to 12 inches” refers to the workpiece width supported by the jig; it does not mean every joint style can be cut across that full width under every setup.
Choose by the joints you actually make
Mostly drawer fronts: half-blind dovetails
Half-blind dovetails leave the joint hidden from the front of a drawer, making them a practical choice for drawer construction. A 4210 may be enough if you want this joint alone and can find a complete, compatible package. With a 4212 or 4216, the extra templates are useful only if you expect to use them; don’t pay a premium for a broader kit that will sit unused.
Visible corners and casework: through dovetails
Through dovetails show at the outside corner and suit boxes where the joint is part of the appearance. Look for a package that includes the correct through-dovetail template, rather than assuming every Porter-Cable jig includes one. Matching the bit and guide bushing to the template matters: a template from another system is not automatically compatible just because it looks similar.
Cabinet parts or boxes: sliding dovetails and box joints
Sliding dovetails join a long groove-like socket to a matching tail, often for shelves or dividers. Box joints use square fingers rather than angled dovetail tails and are useful for strong, visible corners. These options make the 4212’s broader template selection appealing, but verify which templates are in the actual box. Model number alone is not a safe substitute for an inventory check, particularly for used tools.
What else do you need to get started?
A jig kit is not necessarily a complete cutting setup. Before purchase, check for the following:
- Router: A router compatible with the jig’s guide-bushing setup. Confirm the router base accepts the required bushing or adapter.
- Guide bushing: The correct diameter and mounting style for the specific template. Some packages include one; others may require a separate or model-specific part.
- Router bits: The specified dovetail bit, straight bit, or other cutter for the joint you intend to make. Check shank size against your router’s collet and use the bit dimensions given in the manual.
- Clamps and work support: The jig must be secured to a sturdy bench, and the boards must be clamped firmly in the correct position.
- Setup aids: A square, measuring tools, scrap of the same thickness, and the model’s instructions. Test cuts on scrap are essential for dialing in fit before cutting finished stock.
When inspecting a used jig, count the templates, guide fingers or stops, clamps, mounting hardware, and any included bushings and bits against the manual’s parts list. A missing template may be a bigger problem than a worn-looking finish; a missing specialty clamp or proprietary part can also erase the apparent savings.
Match the jig to your stock and workload
| Your situation | Better starting point | Why |
|---|---|---|
| First jig; occasional drawers; limited budget | Complete 4210 package, if half-blind joints meet your needs | Fewer templates to pay for and learn; prioritize completeness and compatible router parts. |
| Several joint styles; regular furniture or cabinet work | 4212 or a complete 4216 package | Multiple templates reduce the need to buy another jig for different joint patterns. |
| Already own a compatible Porter-Cable jig | Correct replacement template or missing part | Replacing only what is needed can cost less and takes less storage space than another complete jig. |
| Mostly wide panels or stock thicker than the stated limit | Compare a different jig designed for that work | The commonly stated 1-1/8-in. thickness and 12-in. width limits may rule out the project. |
For a practical fit check, measure the actual board thickness—not just its nominal lumber size—and compare it with the jig’s published maximum of 1-1/8 inches. For example, a board measuring 1-1/4 inches is 1/8 inch beyond that stated capacity; do not assume it will fit by changing the bit or forcing the clamp. Also check the width of each piece and the orientation required by the template before buying stock for a project.
Setup and ownership: what affects results over time?
Most disappointing cuts come from setup errors rather than a complicated mechanism. Keep mating boards oriented consistently, clamp them flush, and set the bit depth using the instructions for the particular template. Make a test joint from matching scrap. If the joint is too tight or loose, adjust only the prescribed setting, then repeat the test; changing depth and board position at the same time makes the cause harder to identify.
Keep template fingers and bearing surfaces free of pitch and sawdust. Build-up can change how the guide bushing tracks and produce inconsistent cuts. Inspect cutters for dullness or chipped edges, and replace damaged bits rather than trying to compensate with a slower feed. Avoid overtightening clamps, which can dent soft stock or shift the workpiece, and do not plunge or feed the router aggressively. Store templates flat and protect their edges from knocks.
For a used jig, inspect clamps for smooth movement, template edges for damage, and guide parts for looseness or deformation. The templates and accurately locating hardware are central to repeatable joints; cosmetic wear on the frame is less important than bent, missing, or poorly fitting components.
Bottom line
Choose the Porter-Cable 4210 when half-blind dovetails cover your needs and you can confirm the kit includes the parts you need. Choose a complete 4212 or 4216 package for a wider range of joint styles, after checking the actual templates and accessories rather than relying on a model-name assumption. If your stock exceeds 1-1/8 inches thick or 12 inches wide, or if you need a joint not supported by the included templates, compare other jig systems before committing. The best value is the complete setup that matches your work—not simply the package with the most templates.
