- Speed control: Dual-speed units provide refined sharpening and faster material removal; single-speed models favor straightforward duties.
- Wheel and accessories: Look for wheels that match your tasks (grit variety, aluminum oxide wheels, heat management). Tool rests should be adjustable for different angles.
- Motor power and durability: Induction motors with cast-iron bases deliver steadier torque and longer life in busy shops.
- Safety and guards: Cast guards, dust vents, and enclosed bearings reduce debris exposure and improve longevity.
