Key Features To Look For 🧐
Here are the main features that matter:
| Feature | Why It Matters | Recommended Level |
| Motor Power | Determines grinding strength | At least 1/2 HP |
| Wheel Size | Affects grinding surface | 6″ or 8″ |
| Wheel Grit | Impacts smoothness | Coarse + Fine Combo |
| Safety Shields | Protects eyes | Must-Have |
| Base Material | Stability while grinding | Cast Iron Preferred |
A stable, heavy bench grinder performs better because it vibrates less.
Wheel Sizes Explained (6” vs 8”) ⚙️
The two most common sizes are 6-inch and 8-inch wheels. Choosing the right one depends on your work style.
- 6-inch grinders
Good for small sharpening tasks like chisels and hobby tools. - 8-inch grinders
Better cooling, less wheel wear, smoother sharpening for long blades.
If you sharpen tools regularly, go with 8-inch.
Understanding Grit Types For Grinding Wheels
Grinding wheels come in different grit levels, which determine how rough or smooth they grind.
| Grit Type | Best For | Result |
| 36–60 (Coarse) | Removing material fast | Rough finish |
| 80–120 (Medium) | General sharpening | Smooth finish |
| 150+ (Fine) | Polishing & precision | Very smooth |
Most grinders come with one coarse and one medium wheel, giving versatility.
How To Set Up A Craftsman Bench Grinder 👇
Setting up your grinder properly ensures better results and safety.
- Mount the grinder on a solid, flat workbench.
- Ensure the grinder doesn’t wobble.
- Install tool rests and adjust them close to the wheels.
- Attach spark guards and eye shields.
- Plug in and test spin.
Make sure the wheel spins freely with no rubbing.
Safety Tips You Should Never Skip ⚠️
Grinding can throw sparks and debris. Always stay safe.
- Wear safety goggles (not just glasses).
- Use gloves and hearing protection.
- Keep sleeves tight; avoid loose clothing.
- Stay to the side when starting the grinder.
- Let wheels reach full speed before grinding.
If a wheel is cracked, do not use it. Replace immediately.
Sharpening Blades And Tools ✨
A bench grinder makes sharpening fast and precise.
Here’s the basic technique:
- Hold the tool against the tool rest.
- Touch it lightly to the wheel.
- Move steadily across the edge.
- Dip the tool in water to cool it.
Overheating can ruin steel, so cooling is important.
Using A Wire Wheel For Rust Removal 🧲
Switching one of the wheels for a wire brush wheel transforms your grinder into a rust-removal machine.
It can clean:
- Wrenches
- Bolts
- Hinges
- Garden tools
Just press gently and move slowly to avoid bending wire bristles.
Polishing With A Buffing Wheel ✨🌟
You can also attach a buffing wheel to polish metals to a shine. Apply polishing compound and let the wheel do the work.
Common items polished:
- Chrome motorcycle parts
- Brass fixtures
- Steel tools
It gives old parts a like-new finish.
Maintenance And Care For Long Life 🧼
A grinder needs basic maintenance to last for years.
| Maintenance Task | Frequency | Notes |
| Clean dust and metal filings | After every use | Keeps motor vents clear |
| Check wheel condition | Weekly | Replace if cracked or worn |
| Lubricate moving parts | Monthly | Smooth operation |
| Tighten base bolts | As needed | Prevent vibration |
Taking 3 minutes to clean after use goes a long way.
