The best angle grinder for blade-smithing. I've used it heavily for a lil over a year now, almost exclusively on steel. It's frequently been used from sun-up to sun-down (always with frequent breaks of a couple seconds to a couple of minutes to inspect my work and adjust my plans) and it has never bogged down, overheated, or even needed a change of brushes. It cuts at the perfect speed to notice if your steel is losing it's temper (indicated by it's changing colors)I've never gone past a light straw-color with this grinder, but with others i've hit blue too quick for me to quench, ruining knife blades before they even got to be knives. It may cut slower than higher amp grinders, but if you're working on art, tools, or any piece of steel that needs to stay hard, that's a good thing. I think most people giving negative reviews of this grinder don't know how to use angle grinders. From personal experience, i can tell you even professional welders often don't know how to use a grinder properly, so that's no surprise. Angle grinders usually bog down or overheat for one of two reasons, the user not respecting the tools limitations, or using too small of an extension cord. The manual for any power-tool (including this one) has the proper wire guages/lengths to use, and can be found online, so all that's left to speak on is proper technique. You shouldn't push a grinder in any direction with more force than gravity naturally exerts when cutting straight down, until you've begun to learn it's limitations. If you push slightly harder, and it gets a little warmer, that's ok. If it starts getting hot, use less pressure. That said, Harbor Freight does output the occasional lemon. If your angle grinder burns out within the warranty (and if it's a lemon, it should), send it back, and they'll always send you a new one. They've got great customer service, and an outstanding leniency with what they'll take back in returns. Also, I'm pretty sure chicago electric tools are manufactured out-of-country. Political and economical considerations notwithstanding, that makes replacement parts take forever to get shipped, and almost impossible to find. at the price though, you can just replace the whole tool for what some companies charge for replacement parts. Hope this helped someone. I wanted a review like this when i bought mine.

This was the 3rd 4 1/2 inch angle grinder I bought, and the first one from HF.It works well for what it is, but to be honest, it's my least favorite grinder, now out of 5.I like to have several small grinders, each with different type wheels so that I may switch between grinding, cutting, wire wheeling, and such during a job without wasting time swapping wheels.This was the 1st HF grinder I bought, mainly because I needed an inexpensive grinder at the time, and the lowest end grinder sold at HF received such poor reviews.The week I bought this grinder, I was already pulling it apart to fix a broken internal wire. Shortly thereafter, I was swapping the the brushes, then, shortly thereafter, swapping the brushes once again, and again. This all after properly breaking in the tool.The two subsequent grinders I bought at HF were the lowest end, DM grinders, that, in spite of all it's bad reviews, have been less hassle to maintain than this grinder.Perhaps I've just been lucky with the DM grinders, and unlucky with this particular grinder.Besides the fact that it requires replacement brushes so often, while it's not the heaviest of my grinders, it's heavier than the cheapies and has thus far offered me no advantage over those.I'm giving it 3 stars in spite of the negative issues I've encountered with it becasue, in spite of those trivial issues, like most tools I've bought from HF, paid for itself early on.If you're in the market for a light duty angle grinder and aren't expecting great things, this grinder will pay for itself in a short time.The one feature I do like about these and the even less expensive DM's from HF is the push button lock on the gearbox for changing wheels. My two oldest grinders, which I still prefer over these for their longevity and paddle type switches, have no such lock, and require both a flat 7/8 wrench and nipple head spanner (both different sizes) to swap wheels. Both these and the DM's have the push button pin type lock and can share the same spanner for swapping wheels. Most every manufacturer uses a different size or style, proprietary tool for swapping wheels. I like that 3 of my 5 grinders can share a single tool, so if you have a DM, and are, um, upgrading...or supplementing your collection, you can swap your wheels with the same single tool.Overall, you could purchase other grinders and be less happy with them. While my two most expensive grinders are still my favorites, I paid several times for them what these grinders cost me, and I definitely would NOT pay that kinda money for such a tool ever again, thanks to HF!

Awesome angle grinder!

About Me Casual Do-It-Yourselfer
Comments about Chicago Electric Power Tools 4-1/2" Heavy Duty Angle Grinder:
I absolutely love this angle grinder! I purchased it to sharpen lawn mower blades, which it works great for, but ended up using it to cut with as well. I don't use it frequently, but is great at what it does and what I need it for. No maintenance and does the exact same thing another brand would at a fraction of the price! Endless uses for cutting and griding things around the garage or house. Highly recommend this angle grinder!
Bottom Line Yes, I would recommend this to a friend

I know how HF items can be and quality control is not the best on their items. However, if you utilize others' reviews, you can find the hidden gems at HF. This is definitely one of them, powerful and solid! I have been very impressed with this one......
Chicago Elec 4.5" Grinder #91223&42204
Thanks to all for the great reviews on this grinder.I am a 7 year proud owner of a previous 4.5" Chicago Elec. grinder #42204 that served me well until recently. I thot it had a bad switch or brushes discussed in the reviews. So based on your positive reviews, I did buy the #91223 grinder as a backup to my old one.Trying to grind down the diameter of a 1" fender washer yesterday, my old grinder just would not run so I broke the new grinder out of the box added the included grinding wheel and a piece of peel and stick velcro to the bottom of the grinder and to the backside (non-pin side)of the included wheel wrench. This gives you a handy place to store the wrench with the unit and with the wrench pins in the down position acts as rear stand also protecting the rear plastic case if dropped.So, my only experience with the new grinder was to reduce the diameter of the 1" washer too small to place in the vice. So I put a screw thru the washer center hole and hand holding the grinder with one hand placed the edge of the washer about 70 degree angle to the top of the spinning wheel by holding the screw. This allows the washer to turn at slower speed against the grinding wheel removing stock evenly. However, With right hand to close to the wheel I quickly discovered the unit was removing stock from my index finger nail and skin from the end of my finger. I proudly wear a band-aid today to remind me and you to wear protective gloves when working that close to a spinning grinding surface at 11,000 RPMs.If this new grinder is half the tool of the older grinder I will be estatic as the old one was used countless hours grinding and smoothing about 1400 sq feet of fiberglass walkway repair on my houseboat. It was even dropped in the lake once and ran like a champ after it completely dried out. I have never given HF 5 stars on a review but I am so impressed with their small durable grinders that are so light and ez to work with they have earned 5 big ones this time.UPDATE: I took a break writing this review to investigate the failure of the old grinder. The slide switch has a definite click when moved and the brushes are still about 1/2" long. I discovered the power cord has one of those quik-connect plugs where the wire lays on top of two contact pins that are compressed thru the wire insulation to contact the wires. A thin strip of beer can was used to lay over the wire, then, I slid the compression cap over the metal that increased the compression on the wire to make contact with the plug pins. WALLA, BINGO plugged it in and it ran like new. Guess I will let someone else enjoy this old unit and sell for beer money in our Spring garage sale, cause I still have my new HF Grinder 91223 that just loves to eat fingers. Ouch! So, remember to wear those gloves! (:>)

Get this heavy duty version. Well worth the money, and a fraction of the cost of something similar from a box store.I've heard bad stuff about the light duty versions of these that HF carries. I'm using the heck out of this one and I can tell it'll be going strong for a long, long time.Get it on sale, and pick up packs of the wheels on sale to have on hand. Get a variety, masony, metal, grinding wheels. You go through them all quickly.And CONSIDER getting an extra grinder. It's a hassle switching back and forth between wheels, and these are cheap enough you can have two on hand with different wheels. (And you'll *still* come in cheaper than getting one from a box store!)

Many hours of use without a problem
from Sisters, OR
I have owned a Grinder similar to this one (same brand, different location for ON/OFF swith) for over 4 years. NEVER had a problem with it. I have ground paint off of concrete, cut LOTS of metal, polished and shaped items for various projects. I swear by Harbor Freight products. Only problem I have EVER had with a HF Tool was a Timing Light that failed to work after about 2 months. Took it in and they replaced it without question even though it was well passed the warranty period.

Been going strong for 5 years
from Queen Creek AZ
I know many of you reading this will call Bull S.... BUT.I had a Maketa 4" Angle grinder for 2 years using it maybe 30 minutes every 2 weeks for metal and concrete cutting and I had the sanding disk attachment on it to sand down ,rounding the sides of custom Speaker enclosures made from 3/4" MDF.I would also use it to to cut stainless 11 gauge sheets.After a year and a half I nolticed I would have to tap it to get the thing to come on, then eventually it just would not come on anymore. Still decent considering how much it cost(I think it was around $65 from the [@])and the use I got out of it.I decided I was not going to buy another one and figured if the Harbor Freight 4.5" Angle grinder went out on me I'd just take it back under the warranty, and if it lasted just past the warranty then went out I would just figured It would have still been a good deal because it was only going to cost me $17 with tax after the 20% off delio.LET ME TELL YOU.... I have now owed this cheap-O thing for 2 months shy of 5 yrs and besides fading from leaving out in the sun and some paint splatter it's been going strong. Pretty much the same as day one. I still do the same things I did before as when I was using the Maketa, however I have added using it for cutting bricks, and sanding custom formed concrete bolders adding sharp angles that I make for waterfeatures.I would say it's a stronger angle grinder even than the Maketa, but it's also a little bigger by 1/2" so that could be like comparing apples to oranges.Side notes: I pulled the guard off it the first day I used it, just like I did with the Maketa. Seems to always get in the way.I think I've averaged using it during these 5 yrs maybe 1 hour a week.

Cuts diving board bolts in swimming pool deck concrete with ease. 6 bolts - five minutes. Having the correct tool is 95% of the job.Great tool!

About Me Professional
We bought this to use in the field expecting it to get beat up and abused by our guys, so we bought this cheaper one. It serves its purpose well, and it does get abused. We generally just use it to cut anything metal that either sticks out or needs removed such as pipes and poles sticking out of the ground, wire wrapped around things, and 1/2" bolts that are too long on board ups, cutting galvanized pipe on plumbing repairs, etc.This thing has also been put to use in rooms full of sheetrock dust and chimney dust from demolitions, and it still runs. We just use it and abuse it and are fully prepared for it to die and buy another!
