[starttext]They are both very nice. With a standard batteries, I like the Dewalt.
Just a nice feel. When you put an high capacity on the MIlwaukee, it
really changes the feel of the Milwaukee and give it a much better feel
and balance. In regards to power, they are about the same. Both of our
models are still running. I have seen people complain about both and
praise both.

[starttext]Electric ScrewdriversA simple hand screwdriver is useful if you need to
tighten two or three, maximum ten screws. If there are more, the work
becomes a torment. Your hands get sore and blisters appear on them in
just an hour. So if you need to tighten a lot of screws or bolts, it'll
be much better to use an electric screwdriver. It can tighten screws as
small as 3 mm in diameter. This makes electric screwdrivers perfect for
repairing and assembling various devices such as TV sets and computers.
The basic difference between an electric screwdriver and a drill driver
is that drill drivers are much more powerful. However, they can not work
long-term (more than 40 minutes). Electric screwdrivers can be battery
or mains powered. The former are more common and mobile, the latter are
more powerful. Batteries that are used in electric screwdrivers have
voltages from 3 to 7 V.Power of electric screwdrivers ranges from 150 to
200 or 300 W. This is enough for performing most assembly operations.
Torque of electric screwdriver rarely exceeds 6 nm, and the rotation
speed is about 150-200 rpm. All electric screwdrivers have the reverse
function, and the most "advanced" ones have also the "strike"
function.Most electric screwdriver designs do not have sockets; instead,
they have bit holders that secure bits for different types of screws.
Although there are professional screwdrivers with collets. A set of bits
can be quite impressive - up to 150 or 200 items. Handles of most
electric screwdrivers belong to the "break in two" type. They can be
secured in several positions ranging from 90 to 180 degrees with respect
to the body. Electric screwdrivers are usually sold in a special case
along with a set of bits. Some models are equipped with a special stand,
which functions as a charger. MIS 1 Micro Screwdriver with adjustable
torque ranging from 0.35 to 2.0 Nm. It is quiet, light, and has a slip
clutch. It is supplied with 16 replaceable bits of chrome-molybdenum.
This screwdriver is used in automated machine assembly lines, as well as
by modelers and watchmakers. The three stage planetary gearbox offers a
reduction ratio of 93:1, yielding the ideal speed of 200 - 250 rpm,
depending on the type of network adapter which is supplied individually.
The clutch has 5 stages adjustable from 0.35 to 1.0 Nm. Tightening
torques can be selected precisely. The sixth stage bypasses the clutch
and creates a moment of 2.0 Nm. The switch is located on the body and
has three positions: ON - OFF - REVERSE. Fiberglass reinforced nylon
lends high impact resistance to housing. The chuck is designed for bit
shanks up to 6 mm (1/4 inch) in size. The flexible cord is 200 cm long.
The device operates off 12-16V DC. CT-3410 Electric Screwdriver
specifications: Supply voltage: 24V. Rotation speed: 1000 rpm. Operating
time: 2-10 FCT / cm. Slot diameter: 4mm. ST-3420 Electric Screwdriver
has different parameters. The operating torque ranges from 2 to
12kgf/cm, and the slot is 5 mm in diameter. SK-2205LSB, SKD-5300B and
SKD-2000B electric screwdrivers are used for conveyor assembling units
and blocks of electronic equipment. They have a low torque that can be
adjusted with an accuracy of + / - 3%. The screwdriver uses high-quality
engine with a cooling fan for continuous operation. It is light and
small in size, so it can work with tiny screws (up to 1 mm in diameter).
Removable bits allow you to work with all types of screws. When the set
torque is reached, the screwdriver stops automatically. These models
differ in specifications. Specifications: • supply voltage: AC
220V....240V/50 Hz • torque (kg / cm): 0.5 ... 7 (+ / -5%) • rotation
speed (rpm): 1000 • screw diameter (mm): 1.6 ... 2.6 • length (mm) /
weight (g): 230/480 • BIT SS type: 6.5 mm We also provide power supplies
for electric screwdrivers. For example, SKD-2 power supply is designed
for SKD series. Specifications: • Input Voltage - AC 220V (50/60Hz) •
Output Voltage - DC 32/24V • Current - 1A The power supply for
CT-3410/CT-3420 is called ST3200. Its input voltage is 220V. The output
voltage is 30V. The load current is 600mA. You can buy an automatic
screw feeder in addition to your electric screwdriver. It feeds screws
of 2 to 3 mm in diameter one by one. The device has an electronic screw
calculator. The feeder will significantly improve the productivity of
assembly operations. Using electric screwdrivers will help you work more
efficiently and avoid blisters and fatigue.
