Harbor Freight Angle Grinders

There are so many to choose from that I figured I would check with the chorus. I have searched the archives, but the stock at HF has changed. This is the most helpful thread i found, and is why i am getting a cheapy.

Which one would/did you choose? I am buying this tomorrow! Talk about an interactive experience…

Phew!

Thanks in advance, and in retrospect for the collective resourcefulness.

None of these for two reasons.

First, if you’re working on a surfboard you’ll need something with variable speed down to around 1000 to 1500 rpm at times. These 10,000 rpm burners will be near useless on a surfboard.

Second, I went the HF route on a Variable Sander/polisher. Bought the better, stronger, lighter, more expensive one. It failed after maybe 10 hrs worth of use. Opened it up and found a burned circuit in the speed controller. I was pissed.

They are way less expensive. Some people get lucky and some are unlucky. Your choice.

I bought a Makita replacement. Super smooth, balanced and powerful. Not cheap though.

Good luck.

I had a HF angle grinder used for non surfboard purposes. Burned it out in no time. Real junk. If you need an angle grinder, fork out the bucks and get a Millwaukee (sp?). Mine kicks ass. As far as a sander, I just picked up a Porter cable variable speed 6" with the dust kit. Been real happy with it. My experience is $20 power tools are worth $1 and $150 power tools are priceless.

i probably advocated the HF in that other thread…but i must recommend against it. i was actually one of the lucky few who got a good one. i’ve been using my $30 HF sander for a couple years now and it’s still goin’ strong. however, every time i’m ready to use it, i wonder if it’s going to start, or burn out before i’m done sanding. you want your tools to be reliable. if cost is a big concern, see what you can’t find on CraigsList…there’s always some good power tools for cheap on there.

the 7" HF variable speed sander/polisher w/the big loopy handle is KILLER.

$50 regularly…$30 on sale most of the time.

i bought mine with a 2 year warranty for an additional $10…bring it in and i get a brand new one…who cares if they break.

the HF grinder goes from 300 rpm to 3000, better than most expensive ones…its my grinder of choice over ALL other ones, lighter and quieter too…its really good.

yes, everyone knows harbor freight sucks quality wise, but with the warranty, its a no brainer…get one and try it out at least!

I am thinking this grinder will be used for 3-4 boards a year and ding repair. nothing i want to spend a lot of money on, but i suppose dependability is important. 3-4 days is not a long time to wait for a new one though…

Herb Spitzer said something about regreasing them immediately when you get them, and that seemed to work.

I was more wondering what features were legitimately more useful for sanding the hot coat, and polishing the gloss coat.

I just bought a couple of new Milwaukee # 6078, 7" variable speed sander/grinders. $200.00 each. Get the 25’ cord. The one it comes with 8’ is too short. The cords just plug in with a quick release at the handle. Very nice!

This model is extremly light for 13 amp machines and are variable speed from 0-6,000 rpm. Very much a do it all machine, simply awesome!

These are fairly new models so I don’t have a long term experience with them but I have had many Milwaukee’s in use for decades, replacing only brushes and triggers till the machines totally died after thousands of boards many years.

I realize that cost is often a huge consideration but if you can scrape it together, Milwaukees are “forever” tools that you will easily get your money back over the long haul.

Like Ryan said a grinder @ 10000+ RPM is pretty useless for sanding boards and ding repair. Useful for fin foiling though…

Have used my HF sander/polisher for at least 25 boards and ding repairs, not a problem, guess I got lucky.

I know that you get what you pay for, but, for a hobbyist its perfect I reckon

The grinders that you listed are all single speed and need to be modified (remove shield). What you want is a sander. I bought a couple of HF variable-speed 7" sanders about 5 years ago (the model is no longer avail), and have used one almost daily without any problems. The backup has never been out of the box. The choice of tool is really based on usage and what you can afford. If you’re in a production mode, you want to get the best - something that is very reliable and has a proven reputation for producing good work. Same is true if building boards is something you’ll be doing for the next 10 years. For doing a few boards a year or repairs, the HF model 92623-1VGA is OK. I have one and you can sand and polish with it. For $29, you won’t find anything retail that is as good, but you’ll need to get a collection of power pads and spend more time sanding to get results like a Milwaukee. As Herb Spitzer previously recommended, you should clean out and repack the gearhead with a good grease. I recommend Slick 50 PTFE grease which is available at most auto supply stores. I also have a HF model 90820-1VGA sander; it’s only 2 speeds, very heavy, but has a lot of torque. I use this only for polishing. Be advised that backing pads (Power Pad, Ferro) are more than the HF sander itself.

What you really really want is something like this:

Combined rotary action and excentric. Flick the switch…

Rotary:320-660 RPM

Excentric: 3300-6800 Orbits

So for sanding and polishing!

Hook to the shopvac and they sand dustfree…

but they are expensive…

I have the 7" HF variable speed sander. The first time I turned it on, it had a horrible wobble & a bad-bearings noise. I took it apart & repacked the bearings with Milwaukee grease. It got better - enough to be useful.

The variable speed buttons are unhappy that they encounter dust (on a sander - go figure). The + button works with about 960 # of pressure and the - not at all. So when I want to go back down in speed, I have to unplug the tool so it resets and then use the + to get back where I want to be.

I went into a HF store (Napa) a few weeks ago. I couldn’t force myself to buy anything. Not even sandpaper. Its more depressing than a WalMart or a 3rd world Supertienda. Rack after rack of the cheapest crap you can buy. It made me very sad. Cast iron tools with 1/8" ridges where the casts hadn’t matched up. Brand-new power tools that wouldn’t spin by hand without bearing noise. Electrical connections with solders that looked like blind 3 year-olds had done them. Beads of weld with no apparent penetration - they’ll crack apart the first time you have that cement mixer in the back of your truck & hit a bump. Harsh criticism to be sure, but all true.

Buy one tool, you might get lucky. Read the catalog or the website and you might be tempted. Walk into a store and the cover is blown. I’ll not be able to support HF again. Too depressing.

Buy good tools. Your grandchildren will thank you.

Want to buy a slightly used sander? :slight_smile:

Allright, I trust you all. I will not be buying the HF sander/polisher. I am embarrassed for looking at the wrong ones anyways. I found the variable speed ones on there, but i am taking every ones advice and staying away.

I just found this deal at home depot… Too bad, out of stock. I’ll get it from Foamez.

Thanks for the clarification. I’ll let you guys know how it turns out.

Benny, thanks for the tip about the HF stuff in general, I knew it was cheap but that didn’t stop me from filling my “basket” with all kinds of “deals.”

Hey Bill, I ran one of my Milwaukee over with a Ford F-250, took it apart, bent the housing back in shape, and it still runs great.

Buy good tools.

Hey, Kelby -

Let me chime in, a bit late but I have a really good excuse…

First off- steer clear of some of the Home Despot and Lowesy ‘tools’ . Or, if you don’t , check the model numbers Very Carefully versus what you see at a ‘real tool store’ for the same brand tool. What happens is that with those two outfits, they are big enough that the tool company will bring out a special, cheapened edition of a tool. And cut corners, so that it’s just not the same. And of course, the staff at Home Despot and similar tend to be people who have no idea of how to use said tool, so they’ll be of no use in picking one over another. I know one guy works at one of 'em, he used to sell cell phones. You think he knows sander/grinders? Me either.

A kind word for the Orient: look, many of the good-brand tools now are made in the same factories as the HF. Especially bigger shop tools like Delta. I have, for example, a Yuasu or something similar, gasoline powered water pump. Looks just like the Honda that goes for 3x the money. It should…when they made all the Hondas they needed to make for that lot, they made a few more, switched stickers and there ya go. Look carefully, you may find a deal.

Volvo Theory. Huh? Right, Volvo Theory. Look, Volvos have this reputation for lasting forever, and I think I know why. See, when Joe Shmoe buys a Volvo, he figures he spent a bunch of money for a car that’ll last a long time, so he suddenly becomes a maintainance freak and really does the upkeep right. And yes, it does last a long time. But hey, if you did that kind of maintainance that regular, hell, you could make a Yugo go forever. Take care of your gear.

Parallell example: one of my brothers buys nothing but Makita and Yellow and Decker* - oh, sorry, DeWalt. He thinks they are peachy keen. But they live in the open back of his pickup. And die young. Now, me, I have Rockwells. Not Porter Cable, Rockwell, those things are all old enough to vote, at least. And I take care of them. My brother, he actually gives me grief for babying my tools. So, they were better tools then and they are better tools today than the crappe’ he has ever was or ever will be. And will be for the rest of my working life.

*Yellow and Decker - There are some tools I just don’t trust. A new HF item, until I have used it a while and found its quirks. Anything Makita. And everything made by Dewalt/Black and Decker. The former can be a crapshoot, though I have to say that in value for money they can be great. And 90% of the HF stuff I have is good enough for anything but production and for irregular use it’s the nutz. Makita stuff is made for a different kind of hands than I have. They don’t fit. Rockwells and Milwaukees do.

You know what they say: Big hands…

.

.

.

…big tools.

Last, don’t fall in love with the idea of buying new. The indisputably good stuff, like Rockwell and Milwaukee, can be found used, like when a disgruntled employee sells off some good tools, or somebody goes out of business, stuff like that. Repaired tools don’t always get picked up. And the old stuff, even after somebody runs a truck over it, can be worth fixing. Or the newer Hitachis ( two lines of tools, production grade and junk, steer clear of the junk) or Feins or Porter Cables.

Hope that’s of use…

doc…

 Howzit surfer_dave, What does that sander cost? I have been looking at a Bosch that has the same sanding qualities, and I have used them before. A new one runs $300 and a refurbished on is $200 plus shipping ( I can buy the new one on Kauai so no shipping) They work really good and when it comes to blending a new gloss repair to original gloss they are great. For new board sanding I have 2 Makitas, 1 is over 10 yrs and the other is 8 yrs old and have only had to put in new brushes. Aloha,Kokua

Hey Bill,

I got a sander from HF that has out lived the best of the best,cost me 25 bucks back in like 97.I also have the newer HF version variable sander THAT’S A COUPLE YEARS OLD too !..I bought the warranties for my varible and a cordless drill.Never once even had to think about using them.

I also use them for foam/shaping, wood/skateboard use and metal/firearm usage …it’s not normal around here if I don’t fire-up my sanders for a couple …everyday.

I also like my Makita sander,but I kept losing the wrench…not no more…got it taped to the cord.Also the design of the Makita is superior to any of the other sanders due to the fact that it doesn’t use a button stop to remove the pad.This allows for better gearing.Herb

Yebo Kokua!

This is quite funny, alot of US products are sold in Europe and usually we complain because the listprice in the usd has simply been re-labelled to euro. (So a 1000$ laptop becomes a 1000Euro laptop, which is 20% markup!!!) In the case of these sanders I am amazed. Here the 125mm (5") sander cost 445 Euro, I checked the US site and I see it at 350$ !!! And Festool is a German company can you figure this out???

As for the Bosch, you mean this one?

Hey KB,

This the same basic discussion that I read when I was shopping. I went with the HF higher end VS sander. I neglected to buy the extended warrantee. My bad for sure. I cleaned the original grease out and replaced with with Slick50 grease. I think it might’ve been Herb who recommended that. Good tip. Unfortunately, that didn’t help the burnout on the speed controller. Oh yah, I used to think my Ferro sanding pad was warped. It was the HF sander. Didn’t even spin straight.

I’m a hobbyist and didn’t want to spend the dough considering the little amount of work I actually do. I was frustrated that there wasn’t a mid-level version of what I was looking for. I just couldn’t bite the bullet on the cost of what the pro’s are using.

To the guys who’ve bought HF product and had good success, more power to yah. My luck wasn’t as good. I was working one Saturday and the thing took a crap. It had been showing signs similar to what Benny was talking about. It’s hard for me to find much time to do board work so I was bummed when it crashed and I had to go shopping for a replacement.

I looked up a local tool supply place in Anaheim and compared VS sanders. This is the Makita I bought.

http://www.westerntool.com/product.htm?pid=421356 BTW is comes with both a side handle and the D handle as well as a polishing kit.

I chose this one because of the power, rpm range, weight, and name. With very much respect to the pro’s on this board but I thought the Milwaukee was heavy at 9.3 lbs. vs 6.6 lbs. for the Makita. 10 amps has proven to be more than ample (amp joke) and I rarely need to go above 2000 rpm. The electronic speed control is sweet. No more bogging and speeding up. It’s really smooth and I’m happy with it.

I know that cost is up there for us hobbyists. Consider this, these tools are pro level auto detail equipment also. You can kinda justify it that way.

Good luck.

Howzit dave, That’s the one,have used one on wood and resin and they work great, 6" pad . I do own a Rigid 6" random that does 1/8" or 1/4" orbits that sells for about $140.00 and it kicks butt also.

Ryan, That Makita is similar to the ones I own but mine are 1550 - 2800 rpm variables that cost about $50 more and weigh a little over 7lbs. Your model came out after the ones I bought.Aloha,Kokua

I tried Craigslist, and was just 1 hour late for this baby!

Sounds like HF is a total crapshoot. either I will end up with a piece of junk that breaks down immediately, or I will end up with a piece of junk that lasts long enough to keep me from getting a quality tool.

I think I am going to go with a Milwaukee 5540. I have heard so many good things about it, and I know I will be using it for more than just surfboards although mainly for surfboards.

I think Doc is right about how people tend to take good care of their tools(/cars) that they know are good. I know my Toyota is feeling good at 250k miles.

The important thing that I took from this thread is this: If there is a chance that you will be making surfboards for years to come, (Not to mention the environmental cost of throw-away tools) then buy a quality sander/polisher. They will do the job better and will last longer. If you know yourself to be a weekend warrior who will move on to another project in 6 months, go Harbor Freight. Thats why HF exists.

I know I will make my own for the rest of my life so I decided to take the plunge.
