This 2-pack precision jig set combines a drill guide jig and a tap alignment jig to improve accuracy and consistency during drilling and hand-tapping operations. Designed for workshop, garage, and jobsite use, this set helps reduce bit wander, crooked holes, and misaligned threads.

The drill guide jig features a compact 1.75 × 3.00 × 1.00 inch body with eight integrated guide holes for common imperial drill bit sizes: 1/8, 5/32, 3/16, 7/32, 1/4, 5/16, 3/8, and 1/2. Each guide hole is precisely aligned to help produce straight, repeatable holes in wood, plastics, and light metals.

The tap alignment jig uses a rigid 2.00 × 4.00 × 1.25 inch body and includes eight guide holes sized for the most commonly used imperial taps: #6, #8, #10, 1/4-20, 5/16-18, 3/8-16, 7/16-14, and 1/2-13. The perpendicular guide holes help ensure clean, square tap starts and reduce the risk of damaged threads or broken taps.

Both jigs are optimized for 3D printing and can be printed in PLA+, PETG, or ABS with no supports required. Flat bases ensure proper seating on the workpiece, making this set ideal for machinists, fabricators, woodworkers, and DIY users who want reliable, professional-grade results.
