Makita A-47547 Herramienta de rectificado para discos de lijar

The Makita A-47547 is a manual grinding wheel dresser built around a hardened steel star-wheel cutter. Unlike single-point diamond dressers that remove material in one narrow line, the multi-point star wheel works across the full face of the wheel, breaking away glazed abrasive and exposing fresh cutting edges in a single pass. This makes it a practical choice for bench grinders used on a mix of materials, from mild steel to high-speed tool bits.

Highlights

• Star-wheel design trues and dresses most bench grinder wheels
• Hardened steel cutter resists wear and corrosion
• Knurled steel handle provides a secure, non-slip grip
• Manual operation — no power source required
• Suitable for professional workshops and DIY use

In daily use

Hold the dresser firmly against the tool rest and bring the star wheel into light contact with the spinning grinding wheel. Move it evenly across the face to remove glaze, restore the wheel profile, and expose fresh abrasive. The knurled handle helps maintain control, even with gloved hands. Regular dressing improves grinding efficiency and extends wheel lifespan.
