Models DA330D/ DA331D have been developed
as the first 10.8V Li-ion cordless angle drills.
The compact angle head and its small center height allow easy access to
tight spaces where DC driver drills cannot do it.
The difference between these models are as follows;
DA330D/ equipped with Keyed drill chuck
DA331D/ equipped with Keyless drill chuck
