Review7.2-Volt Lithium-Ion Cordless Impact
"sweet spot" for impact drivers is the 18-Volt category because it meets the needs of the broadest range of
users, from professionals to weekend DIY'ers. However, there is an equally great need for an in-line impact
driver that can be used in situations that are just too small, delicate or hard to reach for even a compact
18-Volt and this is where the Makita TD020DSEW 7.2-Volt
Impact Driver excels.
A measure of a company's technical ability is in how much power they can pack into
the smallest possible package and judging by this tool, Makita has shown without a doubt that they are an
industry leader. It has been reported that one will find it difficult to believe that such a small
package actually provides rotational impacts for increased torque unlike a regular drill or driver which does not
need this complicated mechanism, but this tool delivers. All of Makita's impact drivers are very well thought out
and crafted but the Makita TD020DSEW is their crowning effort.
Durable hinge mechanism for maximum
What I really
like about the Makita TD020DSEW is its ability to convert easily from in-line pencil to pistol grip operation
via a durable hinge mechanism. In either configuration, the tool is very comfortable to hold and work with. It
feels solid with its soft grip handle which reduces user fatique tremendously along with its light weight. In
situations where a lot of control and precision is required, for example while working on electrical circuit
boards where a slip could ruin the board or installing small latches and other hardware on cabinetry where a
single scratch or ding could result in the whole piece being rejected, the pencil configuration is perfect. In
situations that require a firmer hold on the tool, for example while driving a screw into a 2 x 4, the pistol
grip is just right. The tool can be locked in either position with a switch. In fact, even the motor can be
locked and the tool used as a plain old screwdriver in the in-line configuration when that is
Real power in a small
As mentioned before, the little TD020DSEW Makita
surprises with its power which is the result of superior engineering. Its proprietary "hammer and anvil" impact
mechanism built with special steels and a unique hardening process along with its lithium-ion technology, allow
this 7.2-Volt tool to put out almost the same power as a 12-Volt cordless tool and twice the torque as other
comparable in-line screwdrivers. To take advantage of extended run time lithium-ion technology, makita
designed a 4-pole motor that is more efficient--it generates power every 90 degrees of motor rotation instead of
180 degrees like a 2-pole motor does and as a result, it runs twice as long as a "regular" 7.2-Volt. The tiny motor
allows the tool to weigh only 1.2 pounds but its dual-steel ball bearings enable the it to deliver 177 pounds per
inch of maximum torque with 2,300 RPM (rotations per minute) and 3,000 IPM (impacts per minute). This allows the
Makita TD020DSEW impact driver to perform a very wide variety of fastening and even drilling operations.
quick-change, hex, Insty bit chuck
This speeds up bit changes and though it only uses hex shank bits, Makita has an accessory that changes the hex
chuck into an older-style 3-jaw chuck for round shanks. This means you can still use older round shank drill bits
if you have them lying around.
Built-in LED light for illuminating tight work
A handy LED light installed just below the chuck
illuminates the tight work areas where this tool is most likely to be used. Very helpfully, it has its own switch
so you can prevent its coming on automatically with every pull of the trigger--an annoyance otherwise. This is
perfect for electrical contractors who are installing wall plates over electrical boxes and switches. For a HVAC
contractor, this would be a much more sensible and versatile tool to carry than an 18-Volt while crawling around in attics and working in tight spaces overhead. Touches like
this along with its Li-Ion technology and its equally well designed charger give the tool an Energy Star
rating and allow it to produce 430% more total lifetime work and 250% more cycles than other comparable

Almost all the users of this tool comment on the benefits of the Makita TD020DSEW's small
size and light weight on the one hand and its surprising power on the other. It is obviously not a heavy-duty
tool or a replacement for one but its authoritative power is unquestionable.
Some users take exception to the noise produced by its impact action and say if it had the same power without
the impact driver noise, it would be a first choice. The noise issue is of course common to all impact tools, at
least for the time being. Some people have apparently had success in reducing the noise by wrapping the tool in
foam and tape. As for myself, I prefer to be able to hear the impact mechanism working so I can tell when it kicks
in as there is precious little tactile feedback otherwise.
