8-piece ball-end hex bit set

The Wiha 71798.G set provides eight ball-end hex bits in SAE sizes ranging from 3/32 to 1/4 inch. Each bit is forged from modified tool steel and measures one inch in length. A storage rail keeps the pieces organised and ready for workshop or job-site use.

Sustained-load behaviour

The bits are not impact rated and are intended for hand-driven or low-torque power applications. Modified tool steel resists rounding during repeated manual fastening but will wear faster under continuous impact loading. The ball-end geometry allows angled engagement without stripping the fastener head.

Setup checks

Confirm that your bit holder accepts a 1/4-inch hex shank before ordering. The set covers SAE hex sizes only, so metric fasteners will require a separate kit. Buyers needing impact-rated bits for hammer drivers should look for a different specification.

Questions about this item

Does the 1/4 in hex shank handle continuous torque without overheating?

The bits are made from modified tool steel and are not impact-rated, so they suit hand-driven use rather than continuous high-torque power tools.

What drive tool is needed to use these 1/4 in hex-shank bits?

Any 1/4 in hex bit holder, screwdriver handle or ratchet that accepts standard 1/4 in hex shanks will drive the 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32 and 1/4 in bits.

Will the 1 in bit length reach recessed SAE fasteners on older equipment?

Each bit measures 1 in long, so it can reach moderately recessed hex heads on legacy machinery while still fitting the included storage rail.
