5 Inch Cutting Disc 125×1.6×22.2mm T41 | Ultra-Thin | OEM Factory China

Qing Yang® manufactures 5 inch T41 cutting discs in 125×1.6×22.2mm specification (5″ x 1/16″ x 7/8″) for OEM buyers, hardware distributors, and tool importers who need a compact cutting disc matched to 125mm angle grinders.

Within the cut-off wheels range, the 5 inch cutting disc is the smallest widely adopted industrial size: larger cutting depth than 4.5 inch wheels, but still light enough for continuous hand-held use on small angle grinders. At 1.6mm thickness, this ultra-thin 125mm cut-off wheel reduces material loss and heat build-up compared with 2.0mm or 2.5mm alternatives, which matters in stainless steel and automotive sheet metal work.

Why 125mm Matters for Compact Angle Grinders

Most compact angle grinders on global job sites are rated for 125mm discs rather than 150mm or 180mm wheels. A 5 inch cutting disc is therefore the default choice where operators want a small, lightweight grinder that still delivers enough cutting depth for everyday work.

Compared with 115mm wheels, the 125mm cutting disc gives additional cutting depth per pass, making it more efficient for cutting rebar, structural angles, and small pipe. Compared with 150mm discs, it keeps the grinder weight and physical size down, which is critical when working in tight-access spaces such as automotive engine bays, pipe racks, and crowded fabrication jigs.

Performance Advantages of the 5″ × 1/16″ × 7/8″ Disc

• 1.6mm ultra-thin kerf – The 5 x 1/16 x 7/8 cutting disc runs at Max 12,200 RPM and 80 m/s. The 1.6mm profile cuts faster, with lower radial load and less heat-affected zone, which directly reduces blueing and grinding rework on stainless steel and thin automotive body steel.
• Double-layer fiberglass reinforcement – A dual glass fiber mesh construction gives the 125mm cutting wheel the fracture resistance needed for confined-access cutting at full speed, while still keeping the disc thin.
• Aluminum oxide T41 formula – The T41A resin-bonded aluminum oxide grain blend is tuned for steel and inox. It keeps a straight, controllable cut in flat bar, rebar, and thin-wall pipe without disc wander.
• Universal 22.2mm (7/8″) bore – The standard 22.2mm arbor fits all mainstream 125mm angle grinder platforms, so distributors do not need separate SKUs for different grinder brands.

Промышленные сценарии применения

Stainless steel and thin-gauge sheet metal
The 125mm disc is ideal for food-grade stainless tube, architectural stainless profiles, and automotive body steel where a narrow kerf and low heat input are more important than maximum cutting depth. At 1.6mm thickness, the disc reduces burr formation and discoloration on inox compared with thicker wheels.

Rebar and small structural steel in tight spaces
On construction sites, the 5 inch cutting disc is used for cutting 10–16mm rebar, angle iron, and flat bar where larger 150mm or 180mm discs cannot fit between cages, formwork, or existing structure. Compact 125mm grinders with 1.6mm discs are easier to control when working overhead or on scaffolding.

Automotive repair and maintenance
Body shops and garages use 5 inch metal cutting discs to separate exhaust systems, brackets, and small structural components. The smaller wheel diameter and thinner kerf give technicians better line-of-sight and more precise control than a 9 inch cutting wheel in confined vehicle spaces.

Workshop and light fabrication
In small fabrication workshops, a 125mm cut-off wheel is the everyday consumable for cutting bar, tube, and plate up to medium thickness. The same T41 disc can be used across steel, stainless, and common alloy steels, simplifying purchasing and stock management.
