Key design feature: an integrated device for round pipes Ø 20-76 mm with trolley angle adjustment from 30° to 90°, allowing for uniform grinding of the pipe's circular surface. A 100 × 2,000 mm abrasive belt (the longest in the Bernardo range) provides an extended contact surface: the workpiece is ground in a single pass without the need for overlaps that would create visible lines. Dual speed (15 \/ 30 m\/s) for stainless steel, aluminum, and non-ferrous metals. Quick belt and roller change without tools to minimize machine downtime. Automatic spring tensioning for constant belt stability during prolonged operations. Dual 2 × Ø 75 mm extraction for abrasive and metallic dust management. In Krollit customers' workshops, the KBR 100 × 2000 Duo is chosen by specialized tubular fabrication workshops, manufacturers of balustrades, railings, furniture frames, and industrial shelving workshops.\u003c\/p\u003e\n\u003ch3\u003eIts place in the range\u003c\/h3\u003e\n\u003cp\u003eThe Bernardo belt grinder range is organized into 4 models by application: BDS 75 (combined belt 75 + disc 150, 1 speed) and BDS 75-2 (same configuration, 2 speeds) for general workshops with mixed processing; BS 100 × 1220 S-2 (belt only 100 × 1,220, 2 speeds, base) for metal fabrication shops with long welds to finish; KBR 100 × 2000 Duo (belt 100 × 2,000 + pipe device Ø 20-76 mm) for workshops specializing in tubular fabrication.\u003c\/p\u003e\n\u003cp\u003eThe KBR 100 × 2000 Duo is the specialized top-of-the-range machine: 2,000 mm long belt, dedicated pipe device, superior dual speed (15\/30 m\/s vs 9.5\/19 for the BS or 11\/22 for the BDS), more powerful motor (2.5\/3.3 kW).
