FAQs

What drill bit sizes can be used with this jig?

The jig is designed to accommodate drill bits up to 2mm in diameter.

How does the jig help with lockwiring?

The jig enables precise drilling of holes through nuts or bolts, which are essential for passing safety wire through to secure the fastener.

What is the main benefit of using this jig?

The main benefit is the ability to quickly and accurately drill holes for lockwiring at variable angles, simplifying a critical safety step in mechanical assembly.

How should I maintain the jig?

Clean off metal shavings after each use and store in a dry environment to prevent rust. Light lubrication on guide surfaces can be applied if needed.

Troubleshooting

Drill bit not aligning correctly

Ensure the correct thread guide for the fastener is selected and the bolt/nut is seated properly within the jig.

Difficulty drilling through hardened material

Use a high-quality drill bit designed for metal. Ensure the drill bit is sharp and consider using a cutting fluid. The jig is designed for standard fastener materials.

Jig feels loose or unstable during drilling

Secure the jig firmly to your workbench or use a vise for maximum stability. Ensure the fastener is tightly seated within the jig's guides.

Hole is not centered

Re-check that the fastener is correctly aligned within the designated guide channel before drilling. Ensure the drill bit is held perpendicular to the jig's surface.
