The trigger switch has a lock-on button for continuous operation.**Flaws but not dealbreakers.** At 6 amps, this grinder bogs down quickly on any serious material removal. It is not suitable for cutting heavy plate or thick steel. The guard adjustment requires the included wrench and is more fiddly than DEWALT or Makita systems.

Understanding them helps you pick the right tool without overspending or underpowering yourself. ### How much amperage do you really need? A 6-amp motor like the SKIL is fine for light cleanup but will stall on heavier beads. For general welding prep and finishing, 8.5 to 11 amps is the sweet spot. The DEWALT DWE402 at 11 amps gives you the best power-to-weight for most shop work. If you regularly cut thick plate or bevel heavy steel, step up to a 15-amp 7-inch machine like the Makita GA7021. That extra power comes with a big weight penalty, so only buy it if you truly need it. ### Tool-free guard vs. wrench systems If you switch between grinding discs, wire brushes, and cut-off wheels multiple times per job, the one-touch guard on the DEWALT DWE4011 saves real time and frustration. Welders who do this all day find it worth the small premium. If you mostly do one type of work per session, a traditional wrench-adjusted guard works fine and is slightly more durable. ### Variable speed: when it matters Variable speed lets you dial down rpm for polishing, cleaning with a wire wheel, or working on thin material. The Makita 9564CV is the only 4-1/2-inch pick here with that feature. If your tasks are mainly aggressive grinding and cutting, fixed speed at 11,000 rpm is fine and saves weight. ### Weight and ergonomics A 4-1/2-inch grinder weighs between 3.4 and 5.3 pounds. For overhead work or long finishing sessions, lighter is better. The SKIL at 3.4 pounds is easiest on the arms but lacks power. The DEWALT DWE4011 at around 4.2 pounds hits a good balance. The 7-inch Makita GA7021 is over 10 pounds and is best kept for work at waist height or on a bench. To see how these factors play out on real picks, compare the [DEWALT Angle Grinder One-Touch Guard 4-1/2](https://www.amazon.com/dp/B009ELXH1K?tag=thetoolwave-20), [DEWALT Angle Grinder 4.5 Inch 11](https://www.amazon.com/dp/B00RVZ7DNO?tag=thetoolwave-20) and the [Makita 9564CV 4-1/2-Inch SJS™ High-Power Angle](https://www.amazon.com/dp/B00005Q7BE?tag=thetoolwave-20) reviewed above. ## Who Should NOT Buy Best Angle Grinder for Welding This category of 4-1/2-inch and 7-inch corded grinders is the wrong purchase for two main types of buyers. Here is who they are, and what to look at instead. ### You Need Portability on a Job Site Without Power If you work on remote job sites, roof repairs, or places without reliable AC power, a corded grinder tethers you to an outlet or a heavy generator. You would be better served by a cordless angle grinder on a 20V or 60V platform from DEWALT, Makita, or Milwaukee. Cordless models trade some run time for total freedom of movement. Just be aware that batteries for 7-inch grinders are very expensive and heavy. ### You Only Need a Grinder for One or Two Small Projects Per Year If you are a homeowner who occasionally needs to grind off a rusted bolt or clean up a single weld, the SKIL 6-amp model might still be overkill. You may be better off renting a grinder from a tool library or borrowing one from a neighbor. The cost of a good grinder is only justified if you use it at least a few times a year. Otherwise, a cheap 4-1/2-inch grinder like the SKIL is fine for occasional use, but do not expect it to last under frequent heavy use. ### You Need to Cut Thick Steel Plate Every Day If your daily work involves cutting 1/2-inch or thicker steel plate, beveling heavy edges, or using large cut-off wheels, a 4-1/2-inch grinder will frustrate you with slow progress. You need a larger machine like the Makita GA7021 or even a dedicated cut-off saw. The 7-inch grinder gives you more wheel surface and motor torque for these jobs, but it requires more skill and strength to control safely. ## Final Verdict The DEWALT DWE4011 with the one-touch guard is the best angle grinder for welding for most welders. It saves you time every time you switch between grinding and brushing, and its compact body fits tight spots around joints. For the money, it is hard to beat. If you prioritize pure cutting power for heavy stock removal, the DEWALT DWE402 with 11 amps is your pick. It is the strongest 4-1/2-inch model here and has the highest owner satisfaction rating. Need speed control for delicate finishing? The Makita 9564CV gives you the only variable-speed option in this group, along with vibration dampening. For heavy plate work, the Makita GA7021 7-inch grinder is the right tool, but only if you are willing to handle the weight. If you are a hobbyist or only grind occasionally, save money with the SKIL 6-amp model. But if you find yourself needing more power, do not hesitate to move up. Before you buy, scroll back up to the "Who Should NOT Buy" section to make sure you are getting the right tool for your real workload. ## FAQ ### What's the best Angle Grinder for Welding overall? The DEWALT DWE4011 with the one-touch guard is the best overall pick for welders who need fast guard adjustments and a compact body for weld cleanup and finishing. It saves time on every wheel swap. ### How many amps do I need for welding prep and cleanup? For general welding prep, 8.5 to 11 amps is ideal. The DEWALT DWE4011 at 8.5 amps handles most tasks, while the DEWALT DWE402 at 11 amps is better for aggressive stock removal. A 6-amp grinder is only suitable for very light duty. ### Should I get a 4-1/2-inch or 7-inch angle grinder for welding? Choose a 4-1/2-inch grinder for weld cleanup, grinding, and most standard jobs. It is lighter and easier to handle. Choose a 7-inch grinder only if you regularly cut thick steel plate or need large surface area grinding. The Makita GA7021 is the only 7-inch model in this guide. ### Is variable speed important for welding work? Variable speed is useful if you do wire-brushing, polishing, or work on thin metal where you need to control heat input. The Makita 9564CV is the only variable-speed grinder here. If you mainly grind and cut aggressively, fixed speed at 11,000 rpm is sufficient. ### How do I keep my angle grinder safe during welding use? Always wear eye protection and gloves, and make sure the guard is positioned between you and the wheel. Use the correct wheel type for the material and speed rating. Do not use a worn or cracked disc. For more on the right tool choices, check out the guide on what this tool is used for that covers general safety practices.
