This precision V-Block drill jig is designed to accurately position and secure round stock for straight, centered drilling. The self-centering 90° V-groove ensures consistent alignment, making it ideal for drilling shafts, rods, tubing, and cylindrical parts in wood, plastics, and light metals.
The compact yet rigid body provides stability during drilling while remaining easy to clamp to a drill press table or workbench. Integrated drill guide holes accommodate the most commonly used imperial drill bit sizes, helping reduce bit wander and improve repeatability. The flat base and symmetrical design allow for reliable positioning and consistent results.
Optimized for 3D printing, this jig is designed to be printed in PLA+, PETG, or ABS and requires no supports. Its durable geometry and practical size make it a valuable addition to any workshop, fabrication setup, or maker space where precise drilling of round material is required.
