Setup
Mounting the Chuck
Follow these steps to properly mount the Jacobs Chuck 30602 onto your compatible power tool.
- Prepare the Spindle: Ensure the spindle of your drilling machine or power tool is clean and free of debris. The Jacobs Chuck 30602 has a 1/2-20 threaded mounting size.
- Thread the Chuck: Align the internal threads of the chuck with the external threads of the tool's spindle. Carefully rotate the chuck clockwise onto the spindle until it is hand-tight.
- Secure the Chuck: For a final secure fit, insert a drill bit or a piece of rod into the chuck jaws and lightly tighten. Then, use the chuck key to give a final firm turn, ensuring the chuck is fully seated and tight on the spindle.
Operating Instructions
Inserting a Drill Bit
Proper insertion and tightening of drill bits are essential for safe and accurate drilling.
- Open the Jaws: Insert the chuck key into one of the holes on the chuck's geared collar. Rotate the key counter-clockwise to open the chuck jaws wide enough to accommodate your desired drill bit.
- Insert the Bit: Place the shank of the drill bit into the center of the chuck jaws. Ensure the bit is inserted as far as it can go without bottoming out, allowing the jaws to grip the cylindrical part of the shank.
- Hand-Tighten: Rotate the chuck collar by hand clockwise until the jaws lightly grip the drill bit.
Tightening the Chuck
- Use the Chuck Key: Insert the chuck key into one of the holes on the geared collar. Rotate the key clockwise firmly to tighten the jaws around the drill bit. For optimal grip, rotate the key in all three keyholes around the chuck, tightening each one sequentially to ensure even pressure.
- Remove the Key: Always remove the chuck key from the chuck before operating the power tool. Operating the tool with the key inserted can cause serious injury.

- Lubrication: Periodically apply a light machine oil to the chuck jaws and threads to ensure smooth operation and prevent corrosion. Do not over-lubricate.
- Inspection: Before each use, inspect the chuck for any signs of wear, damage, or misalignment. Ensure the jaws close evenly and grip securely.
