Product Overview

The RUPES iBrid Mini HSS73 4"x6"x6" Delta Orbital Sander Kit (HSS73/BETA) is a compact professional sanding system designed for precision sanding of corners, edges, narrow surfaces, detailed areas, and other locations that are difficult to access with conventional round or rectangular sanders.

Featuring a 4" × 6" × 6" Delta triangular multi-hole backing plate and a fine 2mm (5/64") orbit, the HSS73 combines precise surface refinement with efficient dust extraction. The delta-shaped sanding platform is particularly useful for shutters, drawers, chairs, cabinetry, woodworking, automotive refinishing, composite fabrication, and sanding or preparation of interior surfaces in marine applications.

The HSS73 features RUPES iBrid Flex Power Technology, allowing technicians to choose between cordless battery operation or continuous plug-in power. Use the included RUPES 18V batteries for maximum mobility or pair the tool with the RUPES iBrid 9HP180LT/US AC-DC Power Adapter, sold separately, for continuous corded operation.

The integrated self-generating dust extraction system allows the HSS73 to collect sanding dust without requiring an external dust extractor when used with the included RUPES Green Tech Filter. This provides excellent mobility for sanding jobs where connection to a shop vacuum or centralized extraction system would be inconvenient.

Pair the HSS73 with RUPES ProCut Film Delta 10-Hole Abrasive Sanding Sheets for a complete professional sanding system.

This HSS73/BETA Deluxe Kit includes the HSS73 Delta sander, two 9HB180LT 18V 2.5Ah Li-Ion batteries, 9HC180LT charging station, RUPES Green Tech Filter, and large RUPES Systainer T-LOC Case (9.CASEIII) for organized storage and transportation.

Features & Benefits

Delta Triangle Sanding Platform

The triangular backing plate is designed to reach corners, edges, narrow surfaces, and detailed areas that are difficult to sand efficiently with conventional round or rectangular sanders.

2mm Precision Orbit

The fine 2mm orbital movement provides excellent sanding control and a consistent finish for surface preparation, refinement, and detailed sanding applications.

Multi-Hole Dust Extraction

The Delta multi-hole backing plate is designed for efficient dust evacuation when paired with compatible vacuum abrasive sheets and the HSS73 dust extraction system.

Self-Generating Vacuum System

The integrated self-extraction system allows the HSS73 to collect sanding dust using the included RUPES Green Tech Filter without requiring an external dust extractor, improving mobility and reducing hose interference while sanding.

RUPES iBrid Flex Power Technology

Choose between cordless 18V battery operation or continuous plug-in power using the optional RUPES 9HP180LT/US AC-DC Power Adapter, sold separately. The dual-power platform gives professional users the flexibility to select the power source that best fits the job.

Electronic Speed Control

The electronic speed control provides five working speeds from 7,000 to 11,000 RPM, allowing the operator to adjust sanding performance for different surfaces, abrasive grades, and applications.

Variable-Speed Throttle Lever

The ergonomic throttle lever provides precise control of tool operation, while soft-start functionality helps provide smooth and controlled startup.

Compact & Ergonomic Design

Balanced weight distribution, compact dimensions, and multiple grip positions make the HSS73 comfortable and maneuverable when sanding detailed surfaces, corners, edges, and confined areas.

Recommended RUPES ProCut Delta Sanding Sheets

Pair the HSS73 with RUPES PROCUT 4" × 6" × 6" Delta 10-Hole Film Abrasive Sanding Sheets for a complete professional sanding system.

RUPES PROCUT Delta sheets feature a durable PET film backing, precision-coated abrasive grain, and a stearate layer designed to improve dust extraction and reduce loading during dry sanding. Available grit ranges make the system suitable for defect removal, surface preparation, and refinement on paint, primer, putty, gelcoat, wood, plastics, metals, and composites.

SMSDistributors Expert Notes

The Delta-shaped sanding platform is a major advantage when working in corners, along edges, inside cabinetry, on shutters, around marine interiors, or anywhere a conventional round sander cannot reach efficiently.
The fine 2mm orbit makes the HSS73 particularly well suited to controlled surface preparation and refinement rather than aggressive material removal.
The self-generating dust extraction system is especially useful for mobile work and detailed sanding where a vacuum hose could interfere with maneuverability.
Two included 9HB180LT batteries allow users to rotate batteries during extended sanding sessions, while the optional 9HP180LT/US power adapter provides another option for continuous corded operation.
Pairing this sander with RUPES PROCUT 4" × 6" × 6" Delta sheets provides a complete RUPES system for detailed dry sanding and dust extraction.
The included Systainer case helps keep the sander, batteries, charger, filter, and related accessories organized for storage or transportation.
