Makita 9556HPG 100mm 840W Angle Grinder with Paddle Switch

Key specs include an 840W motor, a no-load speed of up to 11,000 RPM, 100mm (4 inch) wheel diameter, ergonomic paddle switch, robust metal gear housing, soft-grip handle, protective wheel guard, advanced cooling system, and a lightweight, compact body designed for maneuverability and durability on tough job sites.

First, unplug the tool and remove the wheel guard. Use the provided spanner to loosen the front nut, remove the worn wheel, inspect the new wheel for damage, place the new wheel onto the spindle, securely tighten the nut, reinstall the wheel guard, and ensure everything spins freely with the guard in place before resuming work.

It includes an ergonomic paddle switch that stops the tool immediately when released, a protective wheel guard to shield against debris and sparks, a soft-grip handle for controlled handling, and a robust metal gear housing for durability in demanding environments.

Use cases include metal cutting, surface grinding, edge grinding and deburring, finishing and polishing tasks, and other precision grinding work in metal fabrication, maintenance, and construction settings.

Compared to the Makita GA4530R 4-1/2" grinder, the 9556HPG offers a larger 4" wheel in a compact body with an 840W motor and a paddle switch, delivering straightforward, high-speed grinding in tight spots. Compared to the Makita 9557NB 4-1/2" grinder, the 9556HPG emphasizes 4" utility with similar power and paddle-switch safety, but in a slightly smaller footprint suited for confined spaces. For reference, see these Fepy listings: Makita GA4530R 4-1/2": https://fepy.com/product/makita-ga4530r-4-1-2-angle-grinder and Makita 9557NB 4-1/2": https://fepy.com/product/makita-9557nb-4-1-2-angle-grinder

Yes. Its compact 4" wheel design and lightweight build, along with a comfortable soft-grip handle, make it well-suited for grinding in confined spaces and overhead or awkward angles where larger grinders are impractical.

Always wear appropriate PPE (safety glasses or a face shield, hearing protection, gloves, and a dust mask as needed). Ensure the wheel guard is correctly installed, use both hands to control the grinder, keep loose clothing and hair secured, secure the workpiece, and never force the tool. Regularly inspect the tool for damage and maintain proper ventilation on the worksite.

Keep ventilation openings clear to prevent overheating, inspect and tighten all fasteners before use, check the wheel guard for proper operation, replace worn grinding wheels promptly, and store the tool in a dry, clean area when not in use to extend its lifespan.

If you need a reliable, compact, 4-inch grinder with high performance and a paddle-switch safety feature, the 9556HPG offers a strong balance of power, control, and durability for metalworking and maintenance tasks, making it a solid choice for professional shop use.
