A Buying Guide For The Best Bench Grinder For Lawn Mower Blades
When searching for the best bench grinder for lawn mower blades, you will come across various brands that claim to manufacture top-quality bench grinders. However, not all of them deliver what they promise and turn out to be a waste of money. So, to get your budget’s worth, here are a few factors you should consider when buying the best bench grinder for lawn mower blades:
Composition Of Grinding Wheels
Grinding wheels are made with different materials to cater to different operational requirements. The most common material used for sharpening lawn mower blades is silicon carbide, which imparts an excellent hardness to the wheel.
Besides silicon carbide, aluminum oxide is also used to make grinding wheels suitable for sharpening various blades and tools with hard alloys and steel composition. You might also come across other wheels, such as wire wheels and buffing wheels, utilized for grease removal and metal polishing.
Wheel And Grit Size
Usually, one or two grinding wheels of 6 inches and 8 inches are attached to a bench grinder. When compared, a 6-inch wheel is less expensive and can be utilized for general purposes like sharpening blades, knives, and other tools.
Contrastingly, an 8-inch grinding wheel is ideal for the continuous grinding of blades and tools since it is often paired with a powerful motor. The 6-inch grinding wheels typically weigh around 10-25 pounds, while the 8-inch ones can be 20 to 50 pounds in weight.
Another factor you should look for is the grit size the bench grinder’s wheels offer. It measures the size of embedded abrasive particles that function to sharpen metals. A higher grit size value indicates smaller openings that can effectively sharpen rugged tools and blades.
There are four types of grit sizes; coarse grit (16-24), medium grit (36-60), fine grit (80-120), and superfine grit (150 and above). A bench grinder has grinding wheels of 24 to 120-grit, so opt for one that offers a grit size that matches your work requirement.
Grinding metals releases shards and sparks that can lead to accidental injuries to the eyes and face. To prevent the risk of such injuries, the best bench grinder for lawn mower blades should contain some integrated safety features. It should also have an anti-vibration design for a safe and smooth grinding operation.
An adjustable eye guard or shield over the wheels must be present to prevent debris and sparks from flying. A steel spark resistor or arrestor should also be attached to the eye guard’s position to control the deflection of sparks. Wheel guards must cover the grinding wheels to provide additional safety and prevent unwanted hand injuries.
The best bench grinder for lawn mower blades should come with additional accessories that enhance the grinding experience. These accessories can include:
- An LED light to illuminate the workstation and increase visibility.
- Adjustable tool rests near the grinding wheels to support and accurately position the tools and blades being ground.
- Rubber feet to prevent sliding and provide stability during operation.
- A dust port to collect debris generated from the grinding of metals.
- A water tray to dip heated tools and blades.
Advantages Of Buying The Best Bench Grinder For Lawn Mower Blades
Compared to angle grinders or other grinders, a bench grinder is a convenient option to effectively sharpen tools, blades, and different metal-based objects. It can offer several advantages like:
- With different wheel attachments, you can utilize a bench grinder for various applications such as sharpening, degreasing, and polishing.
- It provides better work control than traditional grinders, enabling accurate grinding without damaging the blade or tool.
- A bench grinder is relatively easy to use and usually has simple integrated controls.
- It is easy to maintain, and the attached grinding wheels can be easily removed when replacement is required.
- Bench grinders are comparatively more affordable than industrial-grade grinders, making them ideal for commercial grinding purposes.
Can you use a bench grinder to sharpen lawn mower blades?
Like a portable angle grinder, you can also use a bench grinder to sharpen lawn mower blades. It can serve as a more convenient way to sharpen the blades as it stays in place and does not need to be moved around. Hence, enabling a much more accurate and fast grinding process.
Moreover, attached adjustable work rests can provide better support for the blades and ensure better sharpening, reducing the possibility of accidental damage.
What is the best grit for sharpening lawn mower blades?
For lawn mower blades, many professionals recommend going for a bench grinder with 60-80 grit grinding wheels. This range of grit size provides the perfect balance of coarse and fine grit for grinding. It can effectively remove materials and precisely sharpen lawn mower blades while maintaining their quality. A much coarser or finer grit can ruin the blade condition and generate high amounts of heat, resulting in ineffective sharpening while wasting time.
How many times can you sharpen a lawn mower blade?
It is generally recommended to sharpen lawn mower blades at least twice per season. However, if you are using your lawn mower frequently, it is better to sharpen the blades after 25 hours of the last use. It can help keep the quality of the blades in top condition and prevent them from getting damaged during frequent grass cutting.
It would help if you opted to sharpen your lawn mower’s blades whenever it hits a rocky surface. Stones impacting the blades can cause the edges to dent or chip, which results in quick wearing, leading to constant replacements.
Does wet grass dull mower blades?
Even though wet grass might seem soft to cut through, it can quickly dull your lawn mower’s blades. The high moisture content causes the grass to bend and clump together, requiring extra effort to be cut. This requirement of extra cutting power puts stress on the lawn mower’s engine and can impact the underlying blades, resulting in dull and ineffective sharpness.
Therefore, when dealing with wet grass, it is better to clean the blades before and after cutting and you should sharpen them on time to prevent dulling.
Getting a bench grinder is convenient for sharpening lawn mower blades and other tools. We hope that through this review and buying guide you were able to find the best bench grinder for lawn mower blades that matches your requirements.
