Hitachi WH18DBDL Brushless Impact Driver
Issue: Issue 302
Posted Date: 6/5/2012
Part of a new
line of 18-volt lithium ion brushless motor products from Hitachi is
the WH18DBDL Brushless Impact Driver. Powered by 3.0Ah lithium-ion
slide type batteries (it comes with two), the WH18DBDL is 6"
long and weighs 3.7 pounds. It has a torque of 1,420 inch/pounds for
heavy-duty applications like sinking deck screws and a limited impact
mode in additional to the traditional continuous mode (in which the
tool impacts until the trigger is released). In limited impact mode,
the driver is electronically stopped after about four impacts, in
order to minimize excessive torque when driving small or delicate
fasteners. Four microprocessor controlled speeds, selected with the
push of a button, offer impact rates up to 3,200 bpm. The WH18DBDL
sells for $279.
