SHALLAngle Grinder Tool 7.5Amp 4-1/2 Inch, 6-Variable-Speed Grinders Power Tools, Electric Metal Grinder 12000 RPM w/ 2 Safety Guards, Cutting Wheels, Flap Discs, Non-Slip Handle for Metal/Wood

My husband needed an affordable replacement angle grinder for work since all of his tools got stolen on a job site~ this was the least expensive model I could find~ and so far so good.It cuts and grinds through sheet-metal with no issues at all.He’s been using it every day now for about 3 months. Nothing but a positive experience.The handle is nicely coated; making it comfortable to use and does a really good job at protecting from vibration.It’s got a solid build construction and an extra handle included in the box; this helps keep the machine stable while in use.It came in a heavy duty toolbox sort of case which was A pleasant surprise~ With extra space in there to keep other tools easily accessible~ Like A tape measure and a few screwdrivers fit easily.Also durable enough to keep the machine safe while in rugged work conditions.The Battery life is perfect for his needs~ he gets about 30 minutes of use on one charge and it only takes another 30 minutes to fully recharge it again~He was able to pick up another battery online at a low price just to have in case of an emergency.Also nicely equipped with safety locks. The machine is quite compact considering how powerful it is~Overall, I am extremely pleased with this grinder for $100 it was an amazing value and I look forward to trying other tools from this brand in the future.

This angle grinder feels sturdy in your hand, looks sharp, and it's been working perfectly for me at a really good price. I really love the variable speed feature—it makes tasks like cleaning rust or smoothing out concrete blocks with a wire brush for gluing much easier compared to those single-speed grinders. I bought this grinder specifically for auto body work, cutting metal patches, and projects. It's also handy for roughening up metal when I'm putting in new panels on cars and trucks. Surprisingly, it's also effective for roughing out fiberglass when I'm repairing broken boat hulls or tractor trailer hoods. The trigger switch is conveniently located—I can start it with just one hand. And I like how you can adjust the handle to different positions for comfort and control. This tool is reliable, and considering the price, it's definitely a steal.

As long as you keep using it, it's great. But the trigger lock is almost impossible to disengage. So, have a switched power supply/cord.Otherwise, it has been just what I needed: a slower speed sander for epoxy countertops.

Pros:1. Awesome bargain for a variable-speed grinder with plenty of power, especially with all the accessories that are included.2. Both types of adjustable, quick-clamp guards included to meet current safety regs.3. Good quality lockable trigger switch.4. Rubbery secondary grip, mountable on either side. Better quality than garden-variety plastic ones.5. No spindle play, nice 'n tight.6. Minor play in gear mesh, not enough to matter to most users.7. Fairly heavy, feels substantial, gives impression of quality.8. Plenty of wheels included for various tasks.9. Replacement brushes included.10. Everything fits perfectly (arbor adapter, 5/8"-11 threads, wrench, etc.).Cons:1. No solid grinding wheel included. See my recommendations for these below.2. No storage case included, unless you count the flimsy cardboard box that everything is tossed into (no separate compartments). Given the many pieces in this kit and considering one must purchase a grinding wheel to make the kit complete, I would have gladly paid a few extra bucks for a proper blow mold case to hold and organize everything. Shall did include a sticker for one's toolbox (or whatever).Update 3-25-23: I purchased the $12.88 (at time of writing) Hyper Tough (Walmart house brand) 19" toolbox for this grinder kit. The box accommodates everything that came with the grinder, plus the solid grinding wheels I purchased (spec'd below) and even the Pomsare sanding kit (model PW820813; ASIN B09WYZMX2Q) that I purchased with this grinder.3. Vibration. It's not too bad at this price point, so this is a minor con.I scoured the interwebz for a corded, relatively powerful, variable speed angle grinder that wouldn't break the bank, and after doing much research into specs, I pulled the purchase trigger on this one.This variable-speed version is just $15 more than their constant-speed version. Included in this kit are 2 felt flap discs, which are are a little over $3 each (model SH122002AE; ASIN number B0B398XBYD), so that's about $6 worth. You're paying just $9 more for an ergonomically superior handle with superior trigger type switch and variable speed.Having variable speed greatly enhances utility of a grinder, as it can be used with various low speed accessories, such as sanding pads, foam polishing pads, shaping wheels, etc. The low cost of upgrading to this version is a no-brainer, so in my cart it went!The clamp guards are nicely done. The clamping force is adjustable via hex nut, and they can be positioned at any angle within the clamp lever's limits of movement (i.e., until it hits the grinder's head).The trigger switch is firm, smooth and solid, with a tactile On/Off snap. There is ≈ 10mm (0.4") travel before positive engagement, so it's not easy to accidentally turn this grinder on. I'm actually surprised at how good quality this switch feels at this price point. The trigger lock works well, easy to engage and release.The plastic secondary/auxiliary grip that can be mounted on either side is reasonably thick walled, has a length and diameter that most users should find suitable, and its rubber coating helps maintain grip and somewhat mitigates vibration transference to hands (as do thick gloves). It's the perfect size grip for my ≈ 100mm (4") wide hand.There is some vibration with this model, but it's not bad, especially considering the price. You'll notice it more with poorly balanced wheels (the heavier the worse, of course), but that applies to any grinder.Spindle play is practically non-existent. There's is some play in the gear mesh, but it's not bad. Looser tolerances at this price point are to be expected, and it certainly isn't a deal-killer with this model.The spindle lock works as it should. There are no issues with it.Don't expect an electric brake at this price. If you need a brake to satisfy regs or just your personal preference, this isn't the grinder for you.Although the manufacturer's product description says "6-speed dial", the speed is continuously variable — any speed can be set between the 6 numbers. I haven't yet checked accuracy of these numbers with an RPM meter.There's a detent only at the #6 setting. Since the control can't go past that point anyway, this detent makes no sense on this tool. It seems that Shall cut costs by using an off-the-shelf thumbwheel control meant for a different device — the detent is probably originally used as an on/off switch then the pot adjusts something.In any case, the speed control is smooth and works perfectly. As with the power switch, the speed control feels like good quality on my unit.I tried an included 60-grit flap disc on a mower blade and it started losing its abrasive quickly. It also rounds off the angle cut due to flap flex, which is of course common among flap discs in general. Flappers aren't the best option for mower blades, so I also added DeWalt grinding wheels to my cart (models DW4523 and DW4514; ASIN numbers B00004RH8I and B00002246K, respectively). I ordered the 2 different types because I wanted to see how each worked with this grinder — they do very well — and I wanted to make sure the 5/8"-11 spindle threads would properly mate with 5/8"-11 accessories from other brands like DeWalt (they do).The DeWalt wheels removed the mower blade metal quickly and their edges still look new after sharpening a rather dull blade.I used an included cutting wheel on some bolts and it worked well.At 7.5 amps and 12k RPM, this grinder has enough power and speed to satisfy most users, and it's more capable than most grinders in this price range.Build quality is surprisingly good, so if the price is indicative or suggestive of anything, it would be reduced durability and longevity. I can't speak to this grinder's durability, as I haven't dropped it or otherwise abused it, and my use has been limited (one mower blade and a couple bolts), so I can't say how long it will last. I'll update this review if my unit craps out on me prematurely with normal use.Verdict:A complete kit should include at least one solid grinding wheel, preferably 1/4" thick. However, I can't find a Shall brand solid grinding wheel available anywhere, which would explain its absence. It's odd that they offer felt flap discs but not a grinding wheel, considering most people buy grinders for.. grinding. The DeWalt wheels I referenced above are cheap and yet good quality, so despite the lack of grinding wheel, the overall value of this kit earned it the 5th star.P.S. I use a SAS face shield (model 5145; ASIN B000RFSLZ4) while grinding. Review pending on that item. I also typically wear safety glasses under the shield — mine is an old pair, NLA, so I have no model recommendation.

Can’t beat it for the price. Cut out floor pans and grinded surface rust off metal with this.! Worked flawless.

Seems like a quality piece. Already have a couple hours on it. Surprised it came with some discs, actually useful. Like the feel of the tool, balanced well. The trigger switch is convenient and well thought out. They also include an extra set of brushes for the motor. Hope it lasts long enough where I'll need them. I actually bought this because of the variable speed. I'm stripping the paint off a car and the 11k-12k speed of my other two grinders was too fast for my purpose here.

If you are not familiar with this tool, you may find it difficult to assemble because the instruction manual is poorly written and illustrations are not detailed enough. The tool appears well made, but I will be returning it. My project is very small, so I will use a simple hacksaw.
