Step-by-Step Guide to Changing the Drill Bit

Learning how to replace the drill bit is straightforward once you understand the mechanics. Modern drills predominantly feature a keyless chuck, which allows for easy tightening and loosening by hand. The metal jaws inside the chuck securely grip the drill bit, and their movement determines how tightly the bit is held.

Loosening the Chuck

• Grip the textured rear section of the chuck firmly.
• Turn it counterclockwise (anti-clockwise) to loosen the jaws.
• As you rotate, the jaws will expand, releasing the current drill bit.

Replacing and Tightening the Drill Bit

• Insert the new drill bit into the chuck, ensuring it is positioned as centrally as possible.
• Hold the bit steady and turn the textured grip clockwise to tighten the jaws around the bit.
• Before fully securing, check that the bit is aligned properly—straight and centered within the jaws.

To verify proper alignment, briefly squeeze the trigger to spin the drill and observe if the bit runs smoothly without wobbling. Adjust as needed to ensure a secure and centered fit, which helps achieve precise drilling and prolongs the life of your drill bit and tool.
