12 best heavy duty bench grinders

Heavy-duty bench grinders are powerful and robust power tools used for various grinding, sharpening, and polishing tasks. They are commonly found in workshops, garages, and industrial settings. These grinders are designed to handle demanding tasks and offer several features and benefits:

  1. High Power: Heavy-duty bench grinders typically have larger and more powerful motors compared to standard bench grinders. This extra power allows them to tackle tough materials and heavy-duty grinding tasks effectively.

  2. Durable Construction: They are built to withstand prolonged and rigorous use. The construction often includes a sturdy cast iron base and body, which provides stability and minimizes vibration during operation.

  3. Wide Range of Applications: Heavy-duty bench grinders are versatile tools suitable for various applications. They can be used for sharpening tools like chisels, drill bits, and knives, as well as for shaping, deburring, and polishing metal and other materials.

  4. Adjustability: Many models come with adjustable tool rests and eye shields, allowing users to customize the grinding setup to their specific needs and ensure safety during operation.

  5. Coolant Systems: Some heavy-duty bench grinders are equipped with built-in coolant systems or have provisions for attaching external coolant systems. This helps to keep the grinding wheels cool and prolong their lifespan.

  6. Variable Speed Control: While not all heavy-duty bench grinders offer variable speed control, some models come with this feature. Variable speed allows for more precise control over the grinding process, making it suitable for a wider range of materials and tasks.

  7. Large Grinding Wheels: These grinders often come with larger grinding wheels, which are better suited for heavy grinding tasks and can cover a larger surface area, speeding up the process.

  8. Safety Features: Safety is a crucial aspect of heavy-duty bench grinders. They typically include safety guards, eye shields, and spark deflectors to protect the operator from debris and sparks generated during grinding.

  9. Steady Performance: Heavy-duty bench grinders are designed to provide consistent and steady performance even under heavy loads. This ensures accurate and efficient grinding results.

  10. Compatibility with Accessories: They can often be used with various grinding and polishing accessories, including wire brushes, buffing wheels, and grinding belts, expanding their functionality.

When using heavy-duty bench grinders, it's essential to follow safety precautions, such as wearing appropriate safety gear like safety glasses and hearing protection. Additionally, maintaining the grinder by regularly inspecting and dressing the grinding wheels is crucial for safety and performance.

Overall, heavy-duty bench grinders are reliable tools for professionals and serious DIY enthusiasts who require a robust and versatile grinding solution for their workshop or job site.

User questions & answers

Question: The grinding wheel? 8"x 3/4"? I need 8"x1" wideth does anyone know
Answer: The DW758 8'' Bench Grinder comes with and is used with 1'' wheels.
Question: Is the tool rest adjustable to any angle
Answer: yes
Question: What is the size of the retaining nut that secures the grinding wheels on this unit? 1" is too small. 1-1/16" too big. Is it metric
Answer: 1 1/16 socket will work if you don’t have 26mm
Question: I'm confused by the claim this grinder 3/4 horse power. A 4.4 amp,120vac induction motor is 1/6 hp per various engineering charts and 3/4 hp 13 amps
Answer: Nameplate says 120 volts 4.2 amps when multiplied, it equals 504 watts. One HP is equal to 746 watts by definition. If it was 100% efficient, which is not possible by the Laws of Physics, it would be 504 divided by 746 or .676 HP. Since most motors are only 90% efficient, that would be .676 times .9 = .608 HP. That is between 1/2 and 5/8 HP. Typical of inflated claims by manufacturers. --Master Electrician--

User questions & answers

Question: Is this a variable speed or single speed
Answer: This is a single speed motor, smooth and powerful
Question: What is shaft size
Answer: The bench grinder has a 5/8" shaft diameter.
Question: What is the RPM of this grinder
Answer: The listed RPM is 3600 @ 60hz 11 amp @ 115V, 5.5 amp @ 230V should you change the setup over to 230V, it comes setup for 115 operation, easy to follow their manual to change the wiring setup to 230. I was going to but didn't bother because this grinder is a beast @ the 115V. I use it with a VanSant MultiTool Belt grinder attachment for steel & other metal fabrication, finishing edges, deburring, and some shaping. Also use the 60 grit on the other side of the grinder for assorted grinder tasks. It comes up to speed almost immediately and so far has not bogged down on anything I've done wit it. Great machine so far not a complaint..! This unit is a Made in Taiwan machine vs a mainland republic of China unit. Hope this helps!
Question: How does this one compare to Jets other grinder, model 577102 which spec wise seems identical except the color
Answer: This one is built to a much higher standard. 1) The wheel flanges on this grinder are large and machined, 577102 has cheap, smaller, stamped steel flanges. What does that mean? The wheels will always run truer on this grinder. 2) The motor on this grinder is another league compared to 577102, equal written specs don't always mean equal performance or durability. This Grinder while pre-wired to run off 120 volts, can also be set up to run off 220 volts. That means longer motor life and easier starting when operating it at 220 volts. The 577102 is strictly 120 volt,. 3) There is the exhaust ports, the ones on this one exit in the back/side toward the center of the grinder to a "T" the 577102 has an oval exit behind each wheel. That means this one is allot easier to hook up to dust collection equipment the longer port length also lessons sparks catching anything on fire. You can look at the two manuals on Jet's website and it spells things out with pics too. 4) Lastly is the switch this grinder has a more expensive removable lock out, 577102 has a cheap toggle switch. This grinder is also OSHA approved for industry where 577102 is not, most likely because of the power switch, OSHA's picky about power switches, they must be large, red and easy to access and lock out.

User questions & answers

Question: I am confused - it says it is 115 volts but it also says it is battery powered. Can you enlighten me? Thanks
Answer: No battery just a plug in for 115 volts.. maybe there is another model that is battery powered this one isn't. I also wouldn't get one that is battery powered. To run a grinder you need all the power you can get and a grinder this size wouldn't last very long with a battery.
Question: Do the wheels spin both directions
Answer: No. Like all grinding wheels I've ever seen, these revolve in a downward direction in the front.
Question: What is the grit of the stone
Answer: 36 grit
Question: Is the stand included
Answer: No, the stand is not included.

User questions & answers

Question: is there a 115 volt version available
Answer: Yes, Although the shafts are short so you will be working close to the housing, unlike the unit designed for buffing.
Question: Is this thing 220v? Keeps tripping my outlets
Answer: I sent two of these back. Not only does it trip a GFCI outlet or breaker, but there is serious (and dangerous) current leakage onto the case of the grinder. To test this, I defeated the ground wire and put my voltmeter on the case of the grinder and measured the voltage to ground. While operating the grinder, the voltage on the case ranges from 90 to 150 volts DC depending on speed. You will get a significant shock if you touch it without a functioning ground wire. This is the reason that the GFCI trips - there is significant currant leakage through the case to the ground wire. I consider this to be a serious and dangerous defect, and cannot believe that this machine passed basic UL testing. I would definitely not recommend this grinder until this problem is fixed.
Question: Can I remove the metal guards and grinding wheels and then add buffing wheels and turn it into a buffer when needed
Answer: Yes, it would be useful. With the variable speed rheostat it has a wide range of uses. Just have to choose the correct type of wheel for your application. The factory wheels are 40 and 60 grit I believe.
Question: Why is it tripping my gfa outlets
Answer: It will take up to a 1" wide wheel.

  • STABILITY: Wide-stance base gives you a stable grinder workstation.

User questions & answers

Question: I don't understand the dimensions. how wide is the base? does it come assembled? can we lower the height? does it have screw in glides
Answer: The base is a triangle that measures about 19 inches wide. It comes dis-assembled. You have to set the top and base on the pole. I have no idea if you can lower the top. I bolted a larger steel plate on the top of mine to accommodate back to back grinders. If you want the base to be shorter, you'd have to cut the pole in the center. I measured about 37 inches from bottom to top. If you are asking if the are glides on the bottom of each foot, nope.
Question: How tall is the jet jps-2a 577172 pedestal stand for bench grinders
Answer: I would have to guess since I am not at home now (traveling on the road). I imagine it's approximately 36 to 42 inches tall.
Question: Is the stand actually White or is it Grey as the picture shows
Answer: It is dark grey. We ordered a grinder. It came in grey instead of white like the pictured showed.
Question: would i be able to bolt a bench vise to this
Answer: First it would definitly have to be bolted to the floor,I don't know if I would trust the cast iron top it could break with pressure and force working with a vice. Just my 2 cents

User questions & answers

Question: What is the rotational speed (RPM
Answer: 120V AC 60Hz single-phase, amperage not listed, but it is a 3/4 HP motor and if it's requirements are similar to my 3/4 HP drill press, it will draw in the neighborhood of 9A
Question: Can you replace the grinding stone with a wire wheel
Answer: The Bench Grinder is rated at 3/4hp @ 3550RPM and the arbor is 5/8". That said, it is not the most powerful grinder I have used. It takes a little while to get up to speed, but once it is at max rpm it seems to have enough power.
Question: What is the Volt/Amperage
Answer: This attachment is probably the best sharpener on the market for someone not working as a professional. I doubt you'll risk ruining the temper of your blade, but if you are unsure of how much heat is being generated when you are using it, put your fingers on the knife and apply the most gentle of pressure. If you are feeling enough heat that you have to remove your fingers, you're pushing too hard. If you move your blade about 1 inch per second with proper pressure, the blade will not heat up enough to burn you, or anywhere near enough to ruin the temper on the blade. If you feel like you need to put more pressure to remove metal faster, you should drop down to a more coarse belt instead.
Question: I've read 1/2" arbor and 5/8 " arbor. I've read 1/2 hp and 3/4 hp. What are the right specefications
Answer: This is very good making flat grinds. Both on handles and blades. However, for shaping handles from blank to finish, I would suggest a spindle sander like the combo by Ridgid.
