The Two Bad Options
You Keep Choosing Between A Tradesman You Can't Afford And A Flex That Dies.
Option 1: The Mester
The tradesman you can barely book - and can't afford.
His hourly rate keeps climbing and a good one is impossible to schedule. You end up paying for a job you could have done yourself - the gate, the railing, the rebar. That's not your fault. It's the cost of not owning the right tool.
Option 2: The Cheap Flex
The no-name flex that seizes after a few dusty jobs.
Cheap grinders have no dust protection by design. Metal swarf packs into the motor windings, the bearing goes, and it overheats and quits mid-cut - so you glove up because it's too hot to hold. The tool failed. You didn't.
There is a third option they never told you about - a proper tool built to survive the work.
The Reason It Survives
Dust Kills Flexes. This One Is Built Against It.
The metal swarf that packs into a motor and burns it out never reaches the windings on the DX373. Here is exactly how.
1
The dust-guard grilles snap off
The removable grilles cover the motor vents. Pop them off in a second - no tools, no fuss. This is the part cheap grinders simply do not have.
2
Tap out the swarf, snap it back on
Knock the trapped metal dust out over your bench, click the grilles back into place, and keep working. The swarf never gets a path into the motor windings.
3
Improved airflow keeps it cool
Cleaner vents plus improved cooling airflow let the 750W motor shed heat under sustained load - so it keeps cutting instead of quitting halfway and forcing you to glove up because it is too hot to hold.
This Is The Proof
This is what would have been inside your motor.
Every pile of dust you tap out of the grille is dust that never touched the windings. That is exactly why it will not burn out like the last one.

The Full Feature Stack
Everything In The Right Place.
The combination same-price flexes simply do not offer - built into one tool.
Removable Dust Guards
Snap-off, cleanable grilles keep metal swarf out of the motor windings. Tap them clean and keep working - the feature that stops burnout.
Improved Cooling Airflow
Better airflow sheds heat under sustained load, so the 750W motor keeps cutting instead of overheating and quitting halfway through the job.
Slim Body For Smaller Hands
A reduced-diameter body you can actually wrap your hand around - even one-handed control on lighter jobs, for men who do not have huge hands.
Anti-Vibration Side Handle
The dampened side handle takes the buzz out of long grinding sessions, so the tool does not leave your wrists numb before the job is done.
Hidden Wrench Storage
The disc-change wrench lives inside the side handle - always there when you need it, never lost in the bottom of the toolbox again.
750W · 12,000 RPM
The right class for home and light-trade 125mm metalwork - fast progress cutting metal and a smooth finish when grinding.
Corded Constant Power
No battery to charge, no battery cost, no fading power mid-cut. Plug it in and it runs at full strength as long as the job takes.
Do The Math
Costs Less Than One Visit From The Mester.
Stop paying by the hour for jobs you can finish yourself in an afternoon.

One grinder. You own it forever.
A tradesman charges for a single visit and walks away. Buy the tool once, do the gate, the railing and the rebar yourself, and keep every forint of the labour you would have paid him - on this job and every one after it.
The Name Behind The Machines
Caterpillar Durability - Now In Your Hand.
CAT is Caterpillar - the name behind the machines that build roads, move earth and run for decades in the harshest conditions. That same durability DNA is what the DX373 brings to a hand grinder: engineered for dust, cooled for continuous work, and built to be the last flex you buy - not a no-name tool you replace next year.

4.9 average from 219+ owner reviews
Quality build, super soft start. Fits well in the hand, and extra plus that the motor dust guard is removable.
Finally a flex that does not quit halfway. Cut through a whole pile of old railing without it getting too hot to hold.
Slim enough that I can control it one-handed for the small stuff. Does not wreck my wrists on longer jobs.
Solid tool, cuts well and the wrench living in the handle is genuinely handy. Would have liked a disc or two in the box, but the grinder itself is exactly what I wanted.
CAT is Caterpillar and you can feel it - proper machine, not a rattly cheap one. Popped the dust guard off after a dusty job and tapped a load of swarf out. That is why the last one died and this one won't.
Did the whole gate myself. Saved the mester's fee.
Before You Order
Straight Answers.
For home and light-trade 125mm metalwork - cutting gate hinges, railing, rebar, deburring welds - 750W spinning at 12,000 RPM is exactly the right class. It makes fast progress through metal and gives a smooth finish when grinding. The higher-wattage grinders are built for continuous industrial cutting all day; for the jobs a DIY-er and light-trade user actually does, this is the sweet spot of power and controllability.
That is exactly what it is built against. The removable dust-guard grilles stop metal swarf from reaching the motor windings - the number one cause of a cheap flex dying - and you can pop them off, tap the dust out, and click them back on. Combined with improved cooling airflow, the motor sheds heat under sustained load instead of getting too hot to hold and quitting mid-cut.
For stationary DIY metalwork, corded is the more sensible choice. You get constant, full power that never fades mid-cut, no batteries to buy or replace over time, and a simpler tool with fewer parts to fail. Plug it in and it runs at full strength for as long as the job takes - no waiting for a charge in the middle of a cut.
It is built with a slim, reduced-diameter body that is easy to wrap your hand around - owners with smaller hands can even control it one-handed on lighter jobs. The dampened anti-vibration side handle takes the buzz out of longer grinding sessions, so you finish the job without your wrists going numb.
