What are the different types of sanders?

Belt Sanders: Uses a continuous loop (belt) of sandpaper. Ideal for removing large amounts of material quickly, such as in initial stages of woodworking.

Orbital Sanders: Has a square or rectangular sanding pad that moves in small orbits. Suitable for fine sanding and finishing work. Good for getting into corners and edges.

Random Orbital Sanders: Combines orbital and rotary motion, with a round sanding pad. Provides a smooth finish without leaving swirl marks. Versatile for both rough and fine sanding.

Detail Sanders: Small, triangular sanding pad designed for precision work. Ideal for sanding in tight spaces, corners, and intricate details.

Disc Sanders: Uses a circular disc of sandpaper mounted on a rotating plate. Often used for shaping and smoothing edges, as well as for larger surface areas.

Spindle Sanders: Features a rotating cylindrical drum that moves up and down. Ideal for sanding curves and contours in wood.

Palm Sanders: Small, lightweight sander that fits in the palm of your hand. Good for light sanding and finishing work, especially in tight spaces.

File Sanders: Narrow, belt-like sanding surface. Perfect for detailed work, such as sanding in grooves and tight spots.

Floor Sanders: Large, heavy-duty sanders designed for sanding floors. Used for refinishing hardwood floors, available in drum and orbital versions.

Drywall Sanders: Often has a long handle and a circular or rectangular sanding pad. Specifically designed for sanding drywall joints and surfaces.

Edge Sanders: Has a belt or disc sander mounted on a table with an adjustable edge. Used for sanding the edges of boards and panels.

Bench Sanders: Stationary sanders mounted on a workbench, often combining belt and disc sanding functions. Suitable for various sanding tasks, including shaping, smoothing, and finishing.

What's the difference between a sander and a polisher?

Sanders are tools designed for removing material and preparing surfaces, using abrasive materials like sandpaper to smooth rough surfaces. In contrast, polishers are used to enhance surface appearance, employing soft pads and polishing compounds to achieve a high-gloss finish. Essentially, sanders are for surface preparation and material removal, while polishers are for finishing and shining.

What are important features to look for?

Power and Speed: Look for adjustable speed settings and sufficient power to handle various materials and tasks.

Dust Collection: A good dust collection system helps keep your workspace clean and reduces airborne particles.

Ergonomics: Comfortable grip and lightweight design reduce fatigue during extended use.

Pad Size and Shape: Ensure the pad size and shape are suitable for the areas you need to sand, especially for detailed or tight spaces.

Ease of Sandpaper Replacement: Quick and easy sandpaper changes save time and effort.

Noise and Vibration: Lower noise and vibration levels enhance comfort and reduce strain during use.

What does amperage and voltage mean?

In sanders, amperage (amps) measures the electrical current flow, with higher amps indicating the tool's ability to handle more demanding tasks efficiently. Voltage (volts) measures the electrical potential; for corded sanders, it's usually standardized (e.g., 120V), while for cordless sanders, higher voltage means more power and longer battery life. Higher amperage generally means better performance under load, and higher voltage in cordless models provides more power and runtime.
