Buying Guide
- Grinding wheel type and thickness: Thinner wheels cut faster but can wear faster. Thicker wheels offer durability for heavy stock removal. Choose based on your material and task requirements.
- Abrasive material: Aluminum oxide is common for steel and alloys, offering a balance of life and cut rate. Stainless steel and harder metals may benefit from specific formulations or coatings.
- Arbor compatibility: Ensure the wheel matches your grinder’s arbor size (commonly 7/8″). Some wheels provide multiple arbor options or adapters.
- Grain concentration and bonding: Higher grain concentration supports aggressive grinding but may demand more control. Bonding affects wheel hardness and heat tolerance; choose based on metal type and grinding speed.
- Vibration and user comfort: Low-vibration designs reduce operator fatigue and improve precision over extended use. Consider packs or bulk options if you frequently grind.
- Pack size and value: Bulk packs offer cost savings for large projects but require storage. For occasional use, smaller packs may be more convenient.
- Accessory compatibility: Confirm that the wheel is compatible with your angle grinder’s RPM range and safe operating speeds to avoid wheel breakage or accidents.
- Application scope: Use general-purpose discs for stock removal, deburring, and edge work, while selecting specific wheels for rust removal or heavy metal cutting when required.
