BOAUR 5" 125mm Premium Cutting Disk 1mm Thin 125 x 1.0 x 22.23mm

The BOAUR 125mm Premium Cutting Disc is built to the same ultra-thin 1.0mm specification used across leading Australian and European cutting disc brands, including the market's premium 125mm offerings. It delivers fast, clean, low-burr cuts on mild steel, stainless steel, and other ferrous metals, with the reduced heat build-up and material waste that come from a genuinely thin, resin-bonded aluminium oxide disc, not a repackaged general-purpose wheel.

Why the 1.0mm thickness matters
On a job cutting box section or angle iron, a thicker disc wastes more material as kerf and drags more, generating heat that can warp thin-wall tube. A 1.0mm disc is the standard choice among fabricators for sheet metal, tube, and light-to-medium gauge steel where precision and speed matter more than raw grinding stock removal. For thicker solid bar or heavy structural steel, a 1.6mm–2.5mm disc holds up better under sustained load, so this disc is best positioned in your listing as the "precision and speed" option rather than the heavy-duty option.

Compatibility
Fits any 125mm angle grinder with a compatible guard. Confirm your grinder's rated no-load RPM is at or below the disc's 12,200 RPM maximum before use, never install a disc rated below your grinder's speed.

Safety note
Always wear eye protection, gloves, and hearing protection. Do not use a cutting disc for side grinding, it is designed for straight, perpendicular cuts only. Confirm your grinder's rated RPM does not exceed the disc's 12,200 RPM maximum.
