Safety Wire Drill Jig for Standard SAE Bolts

This tool makes drilling bolt heads easy and nearly foolproof. You will rarely break a drill bit using this fixture.

This jig drills the hole through the center of the bolt head on #10, 1/4", 5/16", 3/8", 7/16", 1/2", and 5/8" diameter SAE bolts, fine or coarse thread, hex or socket head cap. (Does not work on flange head, 12-point, or metric bolts.) Can be used with a hand drill or with a drill press. The body of the tool is made from aircraft grade aluminum with a hard anodized finish (anodizing color may vary from photo). A spare hard alloy steel drill bushing and two 1/16 inch diameter drill bits are included.

We also offer the Replacement Drill Jig Bushing separately (Part No. 3750-025).
