Factors to Consider When Buying a Bench Grinder
Power and motor specifications The grinder’s motor is the power capacity of the tool. The power needed depends on the task. For heavier tasks, select a bench grinder with a powerful motor. For lighter tasks, pick any model with lower power.
Wheel size and material
Use aluminum oxide wheels for ferrous metals and a silicon carbide wheel for brass, copper, and aluminum. Dress the wheels regularly to remove clogged grains. Replace them when they get too small to use with the tool rest.
Speed options and adjustable settings
Choose one with adjustable speed settings. The speed determines the quality of the grinding process and the tool’s performance.
Safety features and accessories
Attachments like water trays, dust collectors, eye shields, and tool rests enhance safety and ease of use. Use safety gear like glasses, a face shield, hearing protection, and closed-toe shoes.
Durability and build quality
Invest in a high-quality, well-constructed grinder made of sturdy materials like cast iron or heavy-duty steel. A sturdy base prevents wobbling and ensures precision and safety.
Bench Grinder Wheel Types and Applications

Type 1 snagging wheels are straight, 2 to 4 inches in diameter, suited for high-speed die grinders and metal removal, using aluminum oxide grains.
Type 27 grinding wheels are common, featuring a flat profile with a depressed center, allowing flexibility from 0 to 45 degrees. Optimal angles are 25 to 30 degrees, prioritizing wheel longevity over cut rate.
Type 28 grinding wheels, called saucer wheels, have depressed centers for better access in tight spaces, excelling at angles from 0 to 15 degrees.
Wheel Maintenance and Replacement
To replace a wheel, unplug, remove the lock nut, swap the wheel, and reattach the wheel guard.
