Frequently asked questions

General

Sander type

The type of sander determines its primary use. An orbital sander is ideal for finishing. An eccentric sander is best for large surfaces.

Abrasive fixing

The method of attachment affects the ease of replacement. Velcro fasteners allow for quick disc changes.

Suction type

A multi-material sander is versatile. It can be used on wood, metal and plastic.

Dimension

Size determines maneuverability. A compact sander is easier to use in small spaces. A large sander may be more stable for large areas.

Weight

Weight affects comfort. A light sander is easier to handle and causes less fatigue. A heavy sander may provide more stability.

Technical specifications

Rotation speed

The speed of rotation affects the speed of sandinf. A high speed allows for fast sanding. A lower speed is better for precision work.

Disc or blade diameter

The diameter determines the area covered. A large diameter allows you to quickly sand large areas. A small diameter is ideal for details.

Oscillation amplitude

Amplitude affects the fineness of the sanding. A large amplitude will remove more material. A small amplitude is better for a smooth finish.

Belt size

Belt size indicates the width and length of the abrasive belt used. A wider belt covers a larger area, ideal for large, flat surfaces. A narrower belt is suitable for details and tight spaces.

Sanding rotation diameter

The rotation diameter indicates the amount of sanding. A large diameter allows for faster sanding. Smaller diameters are better for details.

Sanding pad diameter

The diameter of the pad must match the diameter of the sanding discs. A larger pad will cover a larger area. A smaller pad is for details.

Power supply and operation

Power supply

A corded sander provides continuous power. A cordless sander offers greater mobility, but is battery dependent.

Power cord

Cord length affects mobility. A long cord allows you to work away from the power outlet without the need for an extension cord.

 

Power

Power determines capacity. More power means faster, more efficient sanding, especially on hard materials.

Electrical voltage

The voltage must be compatible with your power supply. Correct voltage will ensure proper operation without risk of damage.

 

Variable speed

Variable speed allows you to adjust the speed to match the material. This provides greater control and accuracy.

 

Sound specifications

Sound power level

Noise level affects comfort. A low level is preferable for prolonged use.

Sound pressure level

The sound pressure level is the perceived noise. Less noise makes it more comfortable to use.

Noise uncertainty (K factor)

The noise uncertainty measures the accuracy of the indicated sound level. A low uncertainty means a more reliable measurement.

Vibration specifications

Vibration level, metal - wood cutting

Vibration levels affect comfort and safety. Less vibration reduces fatigue and the risk of musculoskeletal disorders.

Vibration k-factor, metal - wood cutting

The vibration k-factor indicates the uncertainty of the vibration level measurement. A lower value indicates a more accurate measurement.
