Magnetic Bit Holder
For around $5, a magnetic bit holder is a great addition to your drill/driver accessory collection. It allows various screwdriver bits to be quickly interchanged, providing one-handed drill use, without having to deal with the locking chuck.

Rotary Rasp
A rotary rasp is the perfect tool for removing 'just a little more' from a hole or wood pattern, and making great, near router-quality cuts. It can be used to grind small or large amounts of wood and is shaped perfectly for widening already-drilled holes. For best results, clean the rasp occasionally with a toothbrush.

Self-Centering Bits for Hinges
Drilling pilot holes and then driving screws in order to hang hinges and other hardware used to be an arduous task. Now there are self-centering hinge bits which allow you to quickly and easily drill perfectly centered holes. Basically, they drive just the right hole to allow screws to seat properly in countersunk hinges and other hardware. To use, simply point the tip of the bit into the hardware's countersunk edge. When the drill is activated, the device's hidden spring adjusts to the space and the bit sinks in nice and smooth—and perfectly centered.

Hexagonal Bit
Imagine having to struggle with the old elbow-shaped hex wrenches for every task that comes your way. Now imagine how much easier those tasks—such as appliance repair or sheet metal work—would be with a bit attached to your drill/driver. Available for under $5, a drill/driver hex bit is just the answer. You can buy them individually or as a kit, with one bit of each size.

Bit for Hanging Drywall
A drywall bit has a contoured barrel which ensures the screw will be driven to the correct depth for hanging drywall panels. It will not damage the drywall or allow the screw to drive too deep, which keeps you from having to continually drive secondary safety screws. For only a couple of dollars, this bit will save you time and valuable elbow grease!
