You don’t always have enough clearance to drill a hole or drive a screw where you need it. Maybe an obstruction blocks the hole, or the combination of drill and bit just won’t fit, as with closely spaced studs. At times like these a tool like Fuller’s flexible extension could come in handy.
This 12″ long, plastic-covered extension can get into tight spaces — it can even drill or drive around corners. The standard 1/4″ drive accepts both hex drill bits and driver bits.
Fuller sells the flexible extension by itself or with a kit containing 10 assorted Phillips, slotted, and square bits in a carrying case. The extension alone retails for about $9. Surprisingly, when it’s available at Amazon, the set sells for less.
