Bit adapter for 4 mm half round shank bits in a 1/4 inch hex drive - Delvo ADA-HR4-D63

The bits of the NK series carry a half round shank of 4 mm diameter and therefore do not fit a 1/4 inch hex drive. This adapter closes exactly that gap. Its hex end seats in the screwdriver and its bore takes the 4 mm shank so that the collar rests against the seat and the bit axis runs centred.

Benefits

• Drives bits with a 4 mm half round shank in any screwdriver with a 1/4 inch hex holder
• Made by the manufacturer for this exact pairing, so the collar of the shank seats properly and the runout stays low
• One stock of bits covers both drive types, no duplicate stock at the workstation
• Takes the NK4D, NK4DM, NK4DX, NK4DB, NK4DT and NK4DST series in 44 mm and 64 mm lengths
• Bit changes need no tool, the bit is fitted as usual

Applications

Electronics and instrument assembly, precision engineering, repair and service work wherever screwdrivers with a 4 mm holder and machines with a 1/4 inch holder are used side by side and should share the same bits.
