This lightweight, compact one-handed delta sander is designed for ergonomic, low-vibration use, ensuring fatigue-free and user-friendly operation. Equipped with a brushless motor, it offers greater efficiency and an extended service life. The sander features electronic speed preselection with four settings, maintaining constant speed through a tachogenerator, with soft start and restart protection. The sanding speed can be adjusted to match the material, and the hook and loop backing pad with a 10-hole system ensures optimal dust extraction, compatible with all standard abrasives. The E-signal switch provides simple, safe operation, with a quick-stop function to prevent trailing of the backing pad. The tool is fitted with a disc brake to eliminate unwanted sanding marks, reducing the need for corrective work. Effective dust extraction is achieved through an integrated system, with the option for external dust extraction using an antistatic suction hose. The impact-resistant filter cartridge, featuring an exchangeable PES filter, allows for easy dust disposal and cleaning, maximizing filter life. This sander is particularly well-suited for overhead work, making it a versatile and efficient tool for a variety of applications.
