Dowel Jig Set – precise, durable alignment for wood joints Key benefits Accurate, repeatable hole alignment: self-centering design ensures matched holes on both workpieces for stronger, cleaner dowel joints. Faster setup and fewer mistakes: adjustable legs adapt quickly to different board sizes, reducing marking and measuring time. Comfortable, stable drilling: ergonomic positioning center reduces wrist strain and keeps the drill steady for consistent hole placement. Built to last with power tools: aluminum-alloy body and stainless-steel guide ring resist wear from frequent use with high-speed drills. What’s included Dowel jig (self-centering, adjustable legs) Drill bushings / sleeves: 6 mm, 8 mm, 10 mm, 13 mm Drill bits: 1/2", 1/4", 5/16", 3/8" Features and compatibility Self-centering mechanism automatically aligns the two halves for matched hole placement. Adjustable legs accommodate a wide range of board thicknesses and edge positions (quick to set and lock). Hardened stainless-steel guide ring ensures precise bit guidance and long service life. Lightweight but strong aluminum-alloy construction balances durability with portability. Designed for use with common high-speed drills; bushings fit listed metric sizes and supplied drill bits in inches. How it solves common woodworking problems Eliminates guesswork: positions holes precisely so dowels fit without forcing or gap-prone joints. Speeds repetitive tasks: once set, the jig lets you drill multiple matching joints faster than measuring and marking each time. Reduces drilling errors: the guide ring and ergonomic center prevent bit drift and wrist fatigue, improving hole quality. Practical use scenarios Building furniture: align legs, rails, and aprons for strong, invisible dowel joints in tables, chairs, and cabinets. Cabinetmaking and shelving: create repeatable, concealed connections for face frames, carcasses, and adjustable shelf supports. Repairs and DIY projects: replace damaged dowel joints or add reinforcement to existing pieces without specialized machinery. Quick usage tips Choose the bushing and matching drill bit for the correct dowel diameter before clamping the jig. Lock the adjustable legs at the same setting for both mating pieces to ensure matched holes. Use steady, moderate drilling speed recommended for your bit and material; the stainless guide ring improves accuracy. Technical specifications Drill bushings: 6 mm, 8 mm, 10 mm, 13 mm Drill bits: 1/2", 1/4", 5/16", 3/8" Body material: aluminum alloy Guide ring material: stainless steel Suitable for use with high-speed drills This dowel jig set provides a practical, durable solution for precise dowel joinery—helping both DIYers and professionals work faster, more accurately, and with less strain.
