14 best low speed grinders

Low-speed grinders, often referred to as slow-speed grinders or low-speed bench grinders, are power tools used for various grinding, sharpening, and polishing tasks. They are related to angle grinders and other high-speed grinders but operate at a much lower RPM (rotations per minute). Here are some key features and uses of low-speed grinders:

  1. Low RPM: The primary characteristic of low-speed grinders is their low rotational speed, typically ranging from 1,500 to 1,800 RPM. This slower speed reduces the risk of overheating and allows for more precise and controlled grinding.

  2. Sharpening Tools: Low-speed grinders are commonly used for sharpening various cutting tools, including chisels, plane irons, and turning tools. The slow speed prevents the tools from overheating, which can negatively impact their tempering.

  3. Grinding Metal: These grinders are also suitable for grinding metal surfaces and removing rust, paint, or other coatings. Their slower speed makes them less aggressive than high-speed angle grinders, making them safer for precision work.

  4. Woodworking: Woodworkers often use low-speed grinders for tasks like sharpening woodworking chisels and shaping wooden objects. The lower speed allows for better control and precision.

  5. Polishing: With the right attachments, low-speed grinders can be used for polishing tasks, such as buffing metal surfaces to a high shine.

  6. Safety: Low-speed grinders are generally considered safer than high-speed alternatives because they are less likely to cause kickback or send debris flying. However, it's essential to wear appropriate safety gear, including eye protection and dust masks.

  7. Variable Speed: Some low-speed grinders come with variable speed settings, allowing users to adjust the RPM to suit the specific task at hand.

  8. Wheel Selection: The choice of grinding wheels is crucial when using low-speed grinders. Different wheels are designed for specific materials and tasks, such as metal, wood, or sharpening. It's important to select the right wheel for the job.

  9. Dust Collection: Consider using low-speed grinders with dust collection systems or connecting them to a vacuum to minimize dust and debris in your workspace.

  10. Maintenance: Regular maintenance, such as cleaning and lubricating, is essential to keep your low-speed grinder in good working condition.

In summary, low-speed grinders are versatile power tools commonly used for precision grinding and sharpening tasks in various industries, including woodworking and metalworking.Their slower speed provides greater control and reduces the risk of overheating, making them a valuable addition to any workshop or toolbox.

User questions & answers

Question: Why did this just go from about $120.00 to 185.00 in just a few days? Was going to buy but way cheaper elseware
Answer: No way in the world I would pay over $100 for this. Its probably a vendor just taking a chance at a high sales price when a cheaper vendor dropped out.
Question: Where are the mounting holes located? Are there one per side or two
Answer: The Rikon Slow Speed Grinder has one mounting hole on each side. The spacing is 6 1/4" center to center of the holes.
Question: Sorry newbioe here - if the shaft is 2inchs long then i'm guessing a 1.5 inch cbn will fit (5/8 arbor) - correct
Answer: Correct it will fit. I had to do some light sanding to remove some minor surface gunk and improve the fit on the arbor to get the cbn to fit. (600 grit on a board against the running motor’s arbor) Additionally I added the pair of matching domed washers to improve centering of the wheel.
Question: what is the size of the arbor
Answer: The arbor is 5/8".

Question: What kind of light bulb does it use
Answer: The center line of the arbor is 7 3/8", plus or minus.
Question: Where it made from
Answer: I have 1 1/2" CBN wheels on my grinder and I used the washers that came with the wheels supplied with the grinder which take up 1" of the arbor length - not a whole lot of thread left, but it works fine. I took the guards off because CBN wheels do not have the danger that ALOX wheels have. I've been very happy with them.
Question: what is the height form bench top to center of arbor
Answer: It is 115v it has variable speed motors that I believe would be internally inverted in voltage

HELPFUL TIPS

  • Before connect the plug to the air tools, it is always a good practice to apply few layers of sealant tape on the thread of the plug which will help prevent air leakage and improve the performance of the air tools.
  • Do not overly tighten the plug which may cause damages to the air inlet then potentially introduce air leakage as well.
  • All our air tools are design to work with 90 psi air pressure. If you have an extra long air hose then increase the air pressure from the air compressor will help compensate the pressure drop when air travel long distance before reach the air tools.
