Qing Yang® focuses on 4 inch cutting wheel wholesale, supplying 100×1.2×16mm T41 ultra-thin discs to distributors and OEM brands that need a dedicated 100mm solution for compact angle grinders. The 1.2mm profile is designed for fast, low-resistance cutting on stainless steel, alloy steel and carbon steel while keeping kerf width small and heat input under control.
Performance advantages of the 4 inch cutting wheel
Ultra-thin 1.2mm kerf for efficient cutting
The 100×1.2×16mm T41 design reduces contact area in the cut, so operators feel less resistance and can move through stainless steel and mild steel faster than with standard 3.0mm 4 inch discs. The narrow kerf also helps to minimise burr formation and reduces the amount of grinding required after cutting.
High-strength structure for 80 m/s operation
High-purity aluminium oxide grain combined with a double-layer fiberglass mesh gives the disc the strength needed to run at the 80 m/s line speed expected of quality 100mm cutting discs, while maintaining a flat, vibration‑controlled cut. This matches the safety envelope used by leading European INOX cutting discs in the same size range.
Optimised for 4″ angle grinders with 16mm bore
The 16mm arbor is compatible with mainstream 4 inch angle grinders and locking nuts, allowing distributors to pair this cutting wheel directly with Bosch‑type AG4 tools and similar machines without adapters.
Multi-metal capability for industrial users
The formulation is tuned for stainless steel, alloy steel and carbon steel so one 4 inch cutting disc can cover a wide range of fabrication and maintenance tasks, from thin-walled profiles to small solid sections.
Industrial application range for the 100×1.2×16mm disc
Metal fabrication on compact workpieces
The 4 inch cutting wheel is ideal for fabricators working on small brackets, profiles and thin plates where a compact angle grinder gives better access than 5 inch and 7 inch tools, and the 1.2mm kerf keeps the cut line tight and clean.
Pipeline system engineering and maintenance
In pipeline projects and plant maintenance, the 100mm ultra thin cutting disc is used for trimming small-diameter seamless steel pipes, branch connections and tie-in points where there is limited space around the joint.
Building structure and rebar processing
On construction sites the disc is suitable for cutting steel cages, stirrups and light H‑beams, especially when workers need a light 4 inch grinder for overhead or confined work rather than heavier large-diameter machines.
Service and repair work in workshops
Repair shops and equipment maintenance teams use the 4 inch cutting wheel for quick jobs on bolts, flanges and small welded parts, where a thin, fast-cutting disc reduces time spent on each intervention and helps keep machines back in service sooner.

OEM and wholesale supply of 4 inch cutting wheels
Qing Yang® positions the 4 inch cutting wheel wholesale SKU for distributors, importers and private label brands who want a dedicated 100×1.2×16mm disc alongside their 115mm and 125mm ranges. The compact diameter and ultra-thin kerf make it a good fit for markets where 4 inch grinders are still widely used in fabrication, construction and maintenance work.
We support OEM and ODM cooperation, including customised resin colours, laser-engraved logos and moisture-proof vacuum packaging so the 100mm cutting disc can be aligned with your existing brand image. Container-based supply from our China factory allows you to bundle 4 inch cutting wheels together with larger diameters in one shipment, simplifying purchasing while keeping stock balanced across the full angle grinder disc range.
Global supply and compliance
The 4 inch cutting wheel complies with BS EN 12413 requirements for bonded abrasive safety and is designed around the 80 m/s operating standard commonly used for premium European INOX discs.Combined with internal burst and bending tests, this gives industrial users confidence when running the 100×1.2×16mm disc at high speed on 4 inch grinders.
Through long-term cooperation with distributors in the Middle East, Southeast Asia, Europe and South America, the product is supplied into fabrication shops, construction companies and maintenance contractors who require a stable, repeatable 4 inch cutting disc rather than low-consistency commodity wheels.
Часто задаваемые вопросы
A 4 inch cutting wheel is the better choice when the work area is tight, the parts are small or the operator prefers a lighter grinder for long shifts.
In markets where compact 100mm angle grinders are still widely used, the 100×1.2×16mm disc provides enough cutting depth for daily fabrication and maintenance work while keeping tool weight and overall package size to a minimum.
The 1.2mm profile gives a narrow kerf and low cutting resistance, so the disc moves quickly through stainless steel and mild steel with less heat and fewer burrs compared with standard 3.0mm 4 inch wheels.
This helps reduce rework on the cut edge and allows operators to complete more cuts per shift with less effort, which is especially useful for repetitive cutting of small profiles, tubes and thin plates.
The 100×1.2×16mm cutting disc is designed for 4 inch angle grinders with a 16mm arbor and standard flanges and guards.
It is suitable for stainless steel, alloy steel and carbon steel, covering typical fabrication tasks, construction cutting and repair jobs where a small, agile grinder is preferred over larger 115mm or 125mm tools.
For wholesale and private label customers, we normally start from a practical minimum order quantity that suits trial orders and regional distributors, with full containers available for high-volume buyers.
OEM options include customised label design, resin colour, barcode and export carton layout, so the 4 inch cutting wheel can be integrated into your existing cutting disc range and presented consistently on shelves and online listings.
