Klein Tools 32791 – Frequently Asked Questions

1) Will the Klein 32791 extension fit my impact driver chuck?
Yes, if the driver takes standard 1/4-inch hex bits. The 32791 has a 1/4-inch (6.4 mm) hex shank, which is the universal quick-change size on cordless impact drivers and drill chucks alike. It's rated for impact use, so hammering action won't shear it.
2) Is a 4-inch bit extension long enough to drive screws down inside a deep electrical box?
The 4-inch (10.2 cm) extension reaches into 3-3/8-inch boxes, which covers the deep boxes electricians hit most often. The extra reach is the point: it gets the driver body out of the box opening so you can see the screw and keep the bit straight on devices and panel terminals.
3) What bits go into the 32791 extension?
Standard 1/4-inch hex insert bits, the common 1-inch style. The 32791 is only the extension, no bits included, so pair it with Phillips, square or slotted insert bits as the job calls for. Klein also packages this extension together with an assortment of bits in the Pro Impact Power Bit Set, Cat. No. 32799.
4) Does the Klein 32791 extension hold the bit by itself or do I need to tape it in?
It holds on its own. The business end has a strong magnet that keeps the inserted bit seated, so the bit doesn't drop out when you pull back from a device screw or work overhead. No set screw or collar to fuss with.
5) Will a regular bit extension survive an impact driver, or do I need an impact-rated one?
Use an impact-rated one. Standard hardened extensions are brittle and snap at the shank under hammering torque. The 32791 is made from S2 impact-rated steel, which trades some hardness for toughness so it absorbs the blows instead of fracturing.
6) How slim is this extension? I'm driving screws through a crowded box with conductors packed in.
The body measures 0.43 inch (1.1 cm) in diameter, so it passes through a box opening alongside folded conductors without you having to push wire out of the way. Overall it's a 4-inch piece weighing 0.8 oz (23 g), light enough that it doesn't unbalance the driver.
7) Can I use this extension as a pry bar or punch in a pinch?
No. Klein's instructions are explicit: do not use the 32791 to pry or chisel. S2 steel is hardened for torque, not bending or struck-tool duty, and it can fracture. Wear eye protection when driving with it and follow the safety instructions in your power tool manual.
8) What is the Klein part number for the 1/4-inch hex impact bit extension on its own?
Cat. No. 32791 is the single 4-inch Pro Impact power bit extension with a 1/4-inch hex shank. If you want it bundled with assorted bit sizes and tips instead, that is Klein's Pro Impact Power Bit Set, Cat. No. 32799.
