Power Tool Accessory Jigs

Common types include drilling guides (for straight, repeatable holes), router jigs (for templates, dovetails, edge guides), sanding jigs (to hold and align stock), crosscut and miter sleds for table saws, and jigs that convert hand tools into guided systems; each is designed to improve accuracy, repeatability, or safety for a specific cutting, drilling, or routing task

Match the jig to the tool model or the task (e.g., drill guide for handheld drills, router template for a 1/4" or 1/2" collet), check compatibility with tool dimensions and material thickness, consider adjustability and mounting options, and prioritize jigs that support the tolerances and repeatability your projects require

Look for precision-machined reference edges, hardened steel or aluminum guide bushings, clear measurement scales, solid locking mechanisms, and low play in moving parts; materials and tight tolerances reduce flex and improve repeatability

Budget options are available under $50 and often use molded plastics and simpler adjustments; to save money, accept fewer adjustment increments, lighter materials, or fixed-size templates, but avoid compromising on critical guide surfaces or bushings if you need high accuracy

Keep mating surfaces clean and dry, periodically lubricate sliding parts per manufacturer guidance, check and tighten fasteners before use, store jigs flat or in protective cases to avoid warping, and replace worn bushings or guides to maintain accuracy

Many universal or multi-fit jigs are made to work with a range of tool diameters and brands, but for tight tolerances or integrated mounting features you may need a brand-specific model; verify fit with your tool dimensions and mounting pattern before buying

Ensure the jig is securely clamped, use proper guards and push sticks as needed, keep hands away from cutting paths, confirm that the jig does not interfere with tool ventilation or guards, and inspect for cracks or loosened parts before each use
