Product Overview

The RUPES BigFoot iBrid Mini HSR73 5" Random Orbital Battery Sander (HSR73/STB) is a compact, self‑generating vacuum sander designed for professional sanding and finishing of wood, composites, paint, plastics, and other surfaces across virtually any industry. Featuring iBrid dual‑power technology, a 2mm (5/64") orbit, and a 5" (125mm) multi‑hole backing pad, the HSR73 delivers exceptional efficiency, dust extraction, and surface quality.

The HSR73’s self‑generating vacuum system eliminates the need for an external dust extractor. Simply attach the included RUPES Green Tech Filter (80.400/C) for outstanding dust collection and unmatched maneuverability. For shop environments, the tool may also be connected to a vacuum using the optional 9GAT2001 electric vacuum hose.

Pair with 5" multi-hole grip abrasive sanding discs for dust extraction.

This Starter Kit includes the HSR73 sander, two 9HB180LT 18V Li‑Ion batteries, the 9HC180LT charging station, and the Green Tech Filter — providing continuous runtime and a complete cordless sanding solution.

Optimized ergonomics, compact dimensions, and modern lines make the HSR73 extremely comfortable and easy to use in multiple grip positions, reducing fatigue while improving precision and efficiency.

Features & Benefits

Design & Ergonomics

Modern lines, balanced weight distribution, and carefully engineered grip positions create a sander that feels natural in the hand and delivers consistent, high‑quality results.

Maximum Flexibility

The 2mm orbit and 5" multi‑hole backing pad provide excellent control and a fine finish, ideal for woodworking, automotive refinishing, marine applications, composite fabrication, and general surface preparation.

Pair this sander with any 5" multi‑hole grip abrasive discs, including RUPES ProCut Film, RUPES Multi‑Purpose Gold, 8‑hole, 9‑hole (Festool pattern), 17‑hole, universal multi‑hole, or net‑style vacuum discs. The HSR73’s multi‑hole backing pad ensures excellent dust extraction and full compatibility with both RUPES and competitor 5" grip sanding discs.

Self‑Generating Vacuum System

The integrated dust extraction turbine allows the tool to operate without an external vacuum. Attach the Green Tech Filter (80.400/C) for outstanding dust capture and mobility.

Electronic Speed Control

Highly visible and easy to adjust, the speed dial offers five working speeds from 7,000 to 11,000 RPM for maximum versatility.

Throttle Lever

Inspired by pneumatic tools, the rubberized variable‑speed lever provides precise control and automatically deactivates the tool if dropped or released.

Battery System

The 9HB180LT 18V 2.5Ah Li‑Ion batteries deliver 35–45 minutes of runtime per charge. The custom charging station provides a full charge in approximately 35 minutes, ensuring near‑continuous operation.
