This 1.5–13mm drill chuck converter (1/2-20UNF) is a compact adapter set designed to expand the functionality of power screwdrivers and similar tools. It accepts round-shank drill bits from 1.5 mm up to 13 mm and features a 1/2-20UNF threaded drill chuck to hold bits securely. The set also provides connection options including a 3/8" SDS Plus shaft and a 1/4" hex shank for quick changes between tool systems. Ideal for DIYers, maintenance staff, and tradespeople who need to switch a cordless screwdriver into a drilling or light grinding tool, this converter simplifies bit changes and broadens tool use without a separate drill. The design supports fast locking and release for routine tasks and fits common shank types used in corded and cordless tools. Note the converter should not be used counterclockwise and is not suitable for impact drivers or applications involving high torque loads. Use this adapter for light drilling, fastening, and occasional grinding conversions where torque demands remain within ordinary screwdriver and drill limits.
