A Better Way to Hold a Bit

Compared with the common round-shank bit, a six-sided hex-shank bit fits firmly in a drill chuck's jaws and won't slip in high-torque situations. If the drill is fitted with a quick-change hex-shank adapter, which uses retractable ball bearings to grip the bit at an indent in the shank, you can quickly switch hex bits without ever touching the chuck. Just pull the adapter back to release the ball-bearing grip on the old bit, insert a new one, then push the adapter forward to re-engage the bearings. For a similar model, try the Stanley Fast Change Connecter, ST-05780; stanleypta.com.
