While not the most common battery-

powered tool, cordless angle grinders have

proven their worth in recent Kondinin

Group tests.

Although not as powerful as their

240-volt counterparts, cordless grinders

can be used anywhere, regardless of a

power supply.

Cutting through a lump of railway iron

will still require a far more heavy-duty tool,

but a cordless angle grinder could have

literally hundreds of uses on-farm such

as cutting off stubborn bolts, trimming

corrugated iron on the shed roof or

sharpening the blades of a hay mower out

in the paddock.

A safer option

Operating off low voltages, the risk of

electrocution is eliminated, making the

grinders a safer tool to operate. Due to

the lower torque, they are less likely to

grab or kick-back than more powerful

240V grinders.

The Makita grinder featured a sensitive

overload light and shut-off, which actually

prevented the tool from kicking back but

could also cut out under heavy cutting.

Most grinder batteries featured some

kind of overload protection to prevent

excessive current draw.

As with any tool producing sparks, there

is always a danger of eye injuries and

setting dry paddocks on fire, so take similar

precautions as when using 240V grinders.

Battery technology leads the way

First examined in the cordless drill

evaluation in Farming Ahead No. 185,

lithium ion batteries have been a revelation

for cordless tools, providing lower weight

battery cells capable of delivering high

current for power tools.

Manufacturers have chosen either to

produce light–weight battery packs to

reduce the overall weight of the tool or

increase the number of cells to make higher

voltage 28V or 36V tools with longer run

time and increased power.

Choose a grinder based on need

Makita (18V) and Hitachi (14.4 and 18V)

grinders were lightest and weighed in

at 2.3 kilograms or less, making them

ideal for a multitude of cutting jobs

where manoeuvrability and ease of use

are important.

TESTED: ANGLE GRINDERS

Cut and run with cordless grinders

With the development of lithium

ion battery technology, cordless

angle grinders are now a more

useful tool with increased grunt

and longer run time. Kondinin

Group put six of these handy tools

through their paces to find out if

cordless angle grinders really do

cut it.

Cordless angle grinders are a

convenient tool for working away from

240-volt power.

The Dewalt 36V and Milwaukee 28V had

the longest battery run-time but were

also two of the heavier grinders tested.

The Makita 18V and Hitachi 14.4V were

the lightest and easiest to use but had

the shortest battery life.

All grinders except the Dewalt DC410

were fitted with lithium ion batteries.

At a glance

All batteries fitted to the grinders were

common to the other tools in each

manufacturer’s range such as cordless drills

and impact wrenches.

This means the tools can be bought

without batteries or chargers for a lower

cost if these are already owned.

Most manufacturers supply the grinders

in ‘naked’ or ‘skin’ kits, without batteries or

chargers.

Dewalt’s 18V model is only available

with battery and charger, while the 36V

model is only available without a battery

and charger.

Milwaukee’s 28V model can be bought in

a kit with a single battery and charger or as

a naked kit.
