The bench grinder uses spinning grinder wheels to remove material from a variety of metals. It is useful for sharpening tools, removing rust, deburring parts, and polishing jobs. It is better for finer sharpening and finishing operations than for removing large amounts of material at a time.
- Metal - steel, iron, other ferrous metals
- No Aluminum, Brass, Copper, Wood, Plastics, or other Nonmetallic Materials
- These materials clog the wheel
- Do Not Wear Gloves. Gloves are a snagging hazard, and can get caught in the spinning wheel.
- Safety glasses and close toed shoes are required in the metal room.
- Long pants are strongly encouraged to protect from any sparks or small metal bits, which can be byproducts of grinding operations.
- The bench grinder will stop if the “Off” switch is flicked or the power cord is unplugged.
- The bench grinder includes eye guards and spark guards to redirect sparks and debris.
- The bench grinder includes wheel guards which cover most of the spinning wheel to minimize catching hazard.
- Do not grind for extended periods of time, as the material will become hot.
Bench Grinder Basics
60 to 80 grit wheels are recommended for sharpening jobs
Safety Notice: Always be careful when working with sharp objects.
Grinding Primary Bevels
How To Use This Tool
- Lift eye shield so it does not contact tool rest or grinding wheel
- Flick power switch to “On” position
- Push material against appropriate grinding wheel.
- Use vise grips or other appropriate clamping for small parts
- A lower grit number (30) is more coarse than a higher grit number (80), which is finer. Use a lower grit, more coarse wheel to remove material more quickly. Use a higher grit wheel for a finer finish.
- Keep all movements gentle and smooth. Remember the spin direction of the grinder.
- Pause periodically to prevent the material from heating too much.
- Flick power switch to “Off” position
- Sweep up or vacuum metal dust which collects behind and around the grinder.
- Lower eye shields
