These are well-made and sturdy drill attachments. Each lets you get at fasteners in confined spaces or where straight-line access is just not possible.
The flex holder is a 12-1/2" long extension that can be bent up to 90° but is most effective at 45° or less. Unlike smaller versions, this one will hold its shape when bent less aggressively and can be held and directed comfortably. The magnetic collar slides forward to hold the heads of ferrous screws securely; sliding the collar back automatically ejects the bit.
The right-angle attachment lets you drive at 90° to the spindle or driver shaft. It has a removable handle that swivels and locks in any position, so you can use it right- or left-handed. The chrome-plated housing contains hardened steel gears and a sealed bearing for smooth operation.
Each tool works in both forward and reverse drive, and has a quick-change bit holder that accepts standard 1/4" hex-shank bits (the right-angle attachment includes a 1" #2 Phillips).
