METAL GRINDING 4" A-80911 - MAKITA

Diameter is 4 inches and it uses a standard grinder arbor. It’s a bonded abrasive wheel intended for metal grinding, but exact grit, thickness, and compatibility details vary by SKU—check the product listing for precise numbers.

It fits most 4-inch angle grinders that use a standard 7/8 inch (22.23 mm) arbor. Always verify your grinder’s arbor size and thread before mounting.

Unplug the tool, remove the existing wheel, place the wheel onto the arbor with the correct face outward, add the appropriate flange(s) and nut, tighten securely, and reattach the guard before testing at idle.

Wear eye/face protection, hearing protection, gloves, and protective clothing. Use the tool’s guard, inspect the wheel for cracks before use, avoid side loads, and do not exceed the grinder’s RPM rating.

Ideal for deburring, edge beveling, weld removal, and general surface prep on metal parts, especially when aggressive material removal is needed.

Check the wheel for cracks, chips, or wear before each use. Store in a dry area, and replace the wheel if any damage is detected or performance drops noticeably.

Lifespan depends on metal type, grinding conditions, and technique. Use moderate pressure and let the wheel do the work to maximize life; replace when you notice decreased performance or damage.

Grinding wheels remove material quickly and are durable for continuous metal grinding, while flap discs provide more gradual finishing and are often better for smoothing surfaces. Choose based on your goal: rapid material removal vs. finer finishing.

Maintain steady, moderate feed pressure, keep the grinder moving to avoid heat buildup, and perform light bursts rather than holding constant pressure in one spot.

Yes. Always mount with the guard in place and wear appropriate PPE (eye protection, face shield if needed, hearing protection, gloves) for safe operation.
