Hettich Accura Dowel Drill Guide Jig - 9079402

Its primary purpose is to ensure precise front-hole drilling for the installation of steel dowels, especially when used with Hettich Rastex connectors.

The jig is designed to work with steel dowels of 20 mm, 24 mm, and 30 mm diameters.

It uses two pick-off pins (Ø15 mm and Ø25 mm) that fit into existing Rastex holes for precise alignment on the workpiece.

The jig includes spacers to accommodate board thicknesses of 15/16 mm, 18/19 mm, and 21/22 mm.

This jig is specifically designed for precise drilling related to Hettich Rastex fittings and steel dowels. While it can be used for combination drilling with wood dowels, its core strength lies in its specialized application.

The drill bushes are made of hardened steel, providing durability and maintaining drill bit accuracy.

The set typically includes the drilling jig, two spacers, two pick-off pins, and an 8 mm drill bit.

Ensure the pick-off pins are fully seated in the Rastex holes and the jig is held firmly against the workpiece during drilling. Verify the correct pick-off pin size and spacer are being used.

Confirm you are using the correct pick-off pins for the specific Rastex hole size. Ensure the workpiece surface is flat and clean where the jig makes contact.

Inspect the hardened steel drill bushes for any signs of damage. If compromised, the accuracy of drilling may be affected. Contact Hettich support or your supplier for replacement options.

Double-check that the correct spacers are selected and properly engaged with the jig for the specific board thickness being used.
