A malfunctioning drill chuck can bring your project to a frustrating halt. Whether your Black & Decker drill chuck won't tighten properly, spins freely without gripping bits or has visible damage, most chuck problems are fixable with the right replacement parts and a few simple tools.

Common Chuck Problems

Chuck Won't Grip Bits: Often caused by worn jaws or debris buildup. Clean thoroughly first, then replace if cleaning doesn't restore the grip.

Chuck Spins Freely: Indicates stripped threads. You'll need to replace the entire chuck assembly.

Visible Damage or Cracks: Replace immediately rather than attempting repairs for safety reasons.

Step-by-Step Chuck Replacement

Step 1: Remove the Old Chuck Open the chuck jaws fully and look inside for a left-hand thread screw (turns clockwise to loosen). Remove this screw completely. Insert an Allen wrench into the chuck, tighten the jaws around it, then turn counterclockwise sharply to break the chuck free from the spindle.

Step 2: Clean the Spindle Clean the spindle threads thoroughly with a wire brush, removing debris, old grease, or corrosion that could prevent proper seating.

Step 3: Install the New Chuck Hand-thread the replacement chuck onto the spindle clockwise. Insert the Allen wrench, tighten the jaws around it and turn clockwise firmly to seat completely. Replace the left-hand thread screw by turning counterclockwise to tighten.

Step 4: Test the Chuck Open and close the chuck several times. Insert different sized drill bits to verify proper gripping across the full range.
