This is the Makita Disc Grinder 18V GA418D\u266a
At our shop, this disc grinder with “low” frequency of use<\/strong>is something we can’t do without in many situations.

When I learned about this disc grinder, I was somewhat surprised by its mechanisms
the “brake” and “paddle switch”<\/strong>\u2014just these features alone significantly enhance its range of applications and safety, don’t you think?<\/p>\n\n\n\n

Being cordless reduces hassle, and being able to stand the grinder upright is another nice feature.<\/p>\n\n\n\n\n\n\n\n

You can adjust the speed from 1 to 5.
That alone makes quite a difference. There are many situations where you don’t need such high RPM.

High RPM means sparks and dust fly farther, so adjusting the RPM according to the situation is important.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It seems the RPM changes even in between settings.
Fuzzy (is that an outdated term?) adjustments might also be possible.<\/p>\n\n\n\n

The “paddle switch” and “brake”<\/strong>are excellent.

With the “paddle switch” you can turn it ON\/OFFwith one hand<\/strong>.

With conventional grindersyou had to go “heave-ho click!”<\/strong>andturn OFF<\/strong>the switch, right?

The “brake”electrically stops the rotation<\/strong>.
Unlike old grindersthere’s barely any “aftertone”<\/strong>.
That “whirrrrrr” sound after turning OFF is minimal\u2014you can set it down right away.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Only at speed 5“High Speed Mode” and “Torque Mode”<\/strong>switch depending on the situation.
When the circle disappearsit’s in “High Speed Mode”<\/strong>
and when the dot lights upit’s in “Torque Mode”<\/strong>
or so I’m told. I don’t really look at these things while working, so I can’t tell…<\/p>\n\n\n\n

When the disc gets caught and rotation drops suddenly, a feature called ATF automatically turns it OFF. I thought this significantly improves safety.

A button press locks the disc during changes. The cover has a one-touch lock.
In recent years, there’s a one-touch disc change system called “XLOCK”<\/a>.<\/p>\n\n\n\n

Some models have adopted it, but since I have existing discs and XLOCK is still expensive, I couldn’t justify the purchase (\uff1b\u2200\uff1b)<\/p>\n\n\n\n

The situations where I use a disc grinder are
\u30fbGrinding chain pins
\u30fbWhen I need to remove a lot of material
\u30fbRough grinding, etc.<\/strong>
I basically hate this work because it’s so dusty.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I mainly use cutting wheels, grinding stones, sandpaper, and wire wheels.
There are Scotch-Brite-like products available recently, so I wonder if they might be convenient if I tried them.<\/p>\n\n\n\n

After all, going cordless is really great (‘\u03c9’)\u30ce<\/p>\n\n\n\n
