Keyless Drill Chucks

Keyless drill chucks are the most common type found on portable drills. They offer quick and convenient chuck locking without the need for a separate key.

Method 1: Hand Tightening

For small drills with low torque, simply hand-tighten the chuck by gripping the chuck body and rotating it clockwise. Ensure the chuck is snug but avoid overtightening.

Method 2: Chuck Key

Some keyless drill chucks come with a small chuck key that can be used for additional tightening. Insert the key into the chuck hole and turn it clockwise until the chuck is securely locked.

Keyed Drill Chucks

Keyed drill chucks require a separate key to lock and unlock them. They are typically found on larger, more powerful drills.

Method 3: Inserting the Key

Insert the key into the keyhole located on the chuck body. The key should fit snugly without wobbling.

Method 4: Turning the Key

Turn the key clockwise to tighten the chuck. The chuck should be locked firmly but not excessively. Overtightening can damage the chuck or drill.

Method 5: Releasing the Key

Once the chuck is locked, remove the key by turning it counterclockwise. Store the key in a safe place to prevent loss.
