A small size grinder is a compact and portable tool used for grinding, cutting, polishing, or sanding various materials like metal, wood, or concrete. These grinders are ideal for light-duty tasks, tight spaces, and DIY projects where a full-sized angle grinder would be too bulky.
Types of Small Grinders:
1. Mini Angle Grinder – Compact version of a standard angle grinder (typically 3″ to 4.5″ disc size).
– Example: Bosch GWS12V-76 (12V Cordless), DEWALT DWE402 (4.5″)
– Best for: Cutting metal, grinding welds, light masonry work.
2. Die Grinder – Smaller than angle grinders, used for precision work with rotary bits.
– Example: Ingersoll Rand 3107G (Pneumatic), Milwaukee M12 FUEL (Cordless)
– Best for: Carving, deburring, polishing.
3. Bench Grinder (Small Models) – Mini benchtop versions for sharpening tools or light grinding.
– Example: WEN 4276 (6-Inch Bench Grinder)
– Best for: Sharpening blades, grinding small metal parts.
4. Rotary Tool (Dremel-style) – Ultra-compact with multiple attachments.
– Example: Dremel 3000, Proxxon Micromot
– Best for: Engraving, polishing jewelry, fine detail work.

Key Features to Consider:
✔ Power Source: Corded (more power) vs. Cordless (portable but limited runtime).
✔ Disc Size: Smaller discs (~3″–4″) offer better control in tight spaces.
✔ Speed (RPM): Higher RPMs (~10,000–30,000) for precision work; lower RPMs (~5,000–8,000) for heavy grinding.
✔ Ergonomics: Lightweight design with a comfortable grip reduces fatigue.
