Brand: Beta Tools
Hex bits are great, but most screwdriver-style tools don't let you apply much torque. The 194 Model driver from Beta Tools gives you the leverage of a full-sized wrench, but in a package specifically designed for use with common hex bits!
Each end has a reversible ratcheting female hex to accept your hex bit (not included). The special hex is closed on one end so the bit won't fall through when you push it into the fastener. The closed end sticks out past the centerline of the wrench, so the torque is applied close to the drive end of the bit instead of the far end.
One end of this wrench accepts common 1/4" hex bits, and the other end accepts larger 5/16" hex bits. The 1/4" hex end measures 18.2mm OD (Ø) x 7.2mm thick (S2). The 5/16" end measures 21.5mm OD (Ø1) x 7.6mm thick (S1). Measures 128mm long (L). Weighs 65g. (23/32" Ø x 9/32" S2, 27/32" Ø1 x 5/16" S1, 5" L, 2.3 oz.) Sold individually. Hex bits sold separately.
