/diy/ - Do It Yourself

what you're missing is the jewish marketing exec getting paid 6 trillion dollars a year to trick you out of your money using buzz words and setting competitive prices.

>>1490256

All right. If a jew was about to give you one of these for free (your choice) which one would you pick?. Brush or brushless?.

>>1490256

what you are is a /pol/tard who said nothing of substance. this is /diy/ where we traffic in facts.

if you have facts supported by non-stormer sources state them, otherwise fuck off back to your safe place, >>>/pol/

>>1490258
what?
>>1490257
brushless motors are more efficient and last longer. go with that.

>>1490262

cool cool. Thank you very much. That's what I read.

>>1490262
>what?

are you seriously retarded?

>>1490266
look bro i'll jam my fucking fist up your ass if you reply to me one more time.

>>1490268

Joke is on you. That is what I wanted.

>>1490258
ah yes, le safe space meme, that'll show him

>>1490243
I use it at work for hours at a time. Excellent choice.

I was all aboard with the brush less stuff untill I got some

>Brushless are quieter

They may not read high on a dB meter but I guarantee you they have a high pitched whine that actually hurts my 32 year old ears

>They have more power

Potentially but my brushed impact driver has a lighter anvil than my brushless impact.

While a heavier anvil sounds better it fucking strips PH2 heads all the time because there is too much initial force required to slip the anvil out of place. If you are using torks, Robertson, allen or hex bits you are ok but don't bring it near a PH2. PH3 is fine.

>>1490302
This guy knows what’s up.

The argument that “Brushed motors last longer” is kind of nonsense nowadays. Both brushed and brushless drills are driven by power transistors, and that’s the part that will fuck off when they get too hot. The days of dad’s 25 year old Milwaukee on it’s 3rd set of brushes still running like a deer are gone. They make the microcontrollers leaner, lighter, more efficient, and more controllable than ever, but power transistors have a shelf life - it’s just a fact. I would say go brushless just because they’re easier on your batteries, but that high frequency switching whine is pretty annoying.

>>1490243
>Should I get the "brush" version?
You should get the Makita version

>>1490616
That's not how you spell Metabo.

>>1490649
*Hitachi
Pass on that

>>1490678
>Hitachi
I'll pass on that. I work for a living.

>>1490685
Metabo and Hitachi are one company now. And metabo is so shit when they bought out Hitachi they changed their name to Hitachi. I'll stick with my makita tools.

>>1490690
>Hitachi
didn't they change it to Hikikomori or something

>>1490302
accurate

but your brushless anvil weight was merely a design choice. theoretically you can put an equivalent power/torque brushless motor in that tool and keep the lighter anvil and have a smaller motor. Your BL impact designer tried to upsize that anvil for whatever reason, probably some hyper fucked marketing requirement

>>1490362
kinda accurate

brushless is definitely more power dense than brushed
but its true you have high frequency noise since you have a tons of harmonics in the 6-step inverter output and machine (the motor)

source; I'm a fucking engineer for a tool company. AMA I guess

>>1490362
also (>>1490903 is me)

also power electronics fail because they're relatively sophisticated embedded systems used in aggressive environments. And, not to mention, because ultimately power tools are seen by big wigs as simple consumer products (even "professional" grade tools). To add to that (my company at leas) has absolutely fucked intense development cycles so there's a good probability something on every newer tool wasn't fully investigated or vetted out or came up as an issue too late for the team to do anything about so powers that be decided to just accept inadequacies and charge ahead.

Anyway enough rant about my job.

AMA

With the correct adapter bits, could one use an impact wrench instead of an impact drill? Both tools seem to perform a very similar function to me.

(Don't be mad if this is a stupid question, I don't own an impact drill and don't know if I should

>>1490965
Yes, but using an impact wrench designed for bolts will probably start stripping fasteners pretty quick. I keep breaking concrete screws with my hammer drill.

I very highly recommend considering Mliwauke fuel impact. You have the 4 power modes and if not for that the drill would be useless cause it's so powerfull and with that feature I never overscrew on weak shut like drywall or w/e

>>1490965
Yes (assuming you mean impact driver and not hammer drill), but be aware of two things:
First, you'll probably have to throttle the speed down to reduce the torque to the point that it won't break things.
Second, the spring on the wrench may be too stiff to trigger the impact mechanism at the torque the smaller fastener needs, so it may go in steady like using a drill to drive a screw. If so, just watch out for an impact as you near the end.

I once adapted down a thousand-foot-pound impact wrench to a #2 Robertson. It drove a #10 deck screw through a 2x4 so fast that it smoked coming out the other side, and it sank the head halfway through the board without triggering the impact mechanism. I advise using a light touch on the trigger.

>>1490965
Also to the above, an impact driver is lighter, more compact, and probably less expensive than an impact wench. It's the better tool for the task, and the entire point of using one is that it makes driving screws fast and easy. An impact wrench would be slower and more cumbersome. A regular drill would work if it's torquey enough.

>>1490243
You realize you aren't getting a stubby drill, right? This is ONLY made for doing and undoing fasteners.

it dont matter since you limpdick homeowners hardly use a drill the batteries will fry long before the drill has lost its shine

>>1490258
SAYFE SPASE
Show me where he was wrong.

>>1491042
Some of us have grown up jobs, kiddo.

>>1490965
you can but it's not really a good idea. the torque will fuck most screws and bits pretty quick

>>1491023
jokes on you, I drywalled my whole house with one of these. It works like a normal drill til you get up to a certain torque (above drywall)

>>1490906
What do you think about Ave's tool teardowns and commentary on brands being bought out by techtronic? He seems to know what he's talking about, but its always hard to tell through his bluster.

>>1492028
That dude talks out his ass on a lot of it. But it is true, these tools aren’t made to last for decades like they used to be. You can tell by the lack of user serviceable parts. Hell, my DeWalt brushed rotary hammer has some sealed motor where you can’t even access the brushes to replace them.

I would scrap the DeWalt and go to Milwaukee

>>1492028
I've only watched a few of his videos
My background is electrical engineering and his is as a machinist/mechanical engineer I think?

I don't know about his commentary on techtronic brands. Have a link?

>>1492110
It's true. Old tools were often overdesigned. Now tool brands are realizing there's a benefit to designing to meet cost and profit margins and meet "good enough" durability requirements.

>>1492548
Not to mention that products that break down regularly in an unfixable way create a stable demand.

>>1492600
Gonna correct it to
>not easily fixable for average guy
to avoid autistic anger.

>>1492114
They’re about the same. Milwaukee has a slightly better tool lineup if you’re a mechanic, like the ratchets. If I had to start from scratch, I would probably go red but you shouldn’t regret going yellow or green.

>>1490979
>fuel
He’s gonna pay quite a bit more, just like DeWalt’s XR line

>>1491023
More and more companies are making drill bits for impact drivers these days. I grabbed pic related so if I need to hang a TV on the wall or something, I can grab the 1/4” impact driver real quick and get it all done with the one tool and one box of bits. Is it ideal? No. Does it work? Yes.

>>1492663
hex-drive drill bits are pretty common now, regular keyless chucks bite down on them better than a standard round drill bit and plenty of people just throw their bits in impact drivers for quick jobs.

hell Makita makes a brushless hybrid impact hammer drill driver that does the job of both tools but only uses 1/4 hex bits.

I'll use this thread for a question.

How do think Hitachi's (Metabo HPT, Hikoki) quality is going to be in the future now that a hedge fund bought them?

>>1492663
>More and more companies are making drill bits for impact drivers these days
hex bits existed before impact drivers even existed?

>>1493341
>>1493362
Yes but they’re advertising them as impact drill bits.
