Description
Drill 10mm (3/8")
Models MT605, MT606 and MT607 have been developed as
the aesthetic change models of maktec drills MT602 and MT603.
Their main features are:
• Industrial performance and durability at less expense
• Compact and lightweight design
• Tool body designed to give maximum power thrust
The specification differences between these three models are;
MT605: Keyed chuck model, without variable speed control
and reverse function
MT606: Keyed chuck model, with variable speed control
and reverse function
MT607: Keyless chuck model, with variable speed control
and reverse function
Model MT607 is available with plastic carrying case as
model number MT607K.
