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 through 5/8 inch 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. A spare hard alloy steel drill bushing and two 1/16 inch diameter drill bits are included.
We also offer the Replacement Standard Drill Jig Bushing separately (Part No. 3750-025). Our Part No. 3744 Bushing for the Deluxe Jig does not fit this Economy model.
