Qing Yang® supplies 4.5 inch cut off wheels in 115×1.2×22.2mm T41 specification to B2B buyers who need an ultra-thin 115mm cutting disc for bulk wholesale orders. Compared with heavier 3.0mm wheels and our 115×3.0×22.2mm T42 heavy duty disc, this 1.2mm 4.5 inch cut off wheel is engineered for fast, low-resistance cutting on carbon steel, stainless steel and structural steel while keeping kerf width and heat input tightly under control.
Product advantages of the 4.5 inch cut off wheel wholesale
Ultra-thin 1.2mm profile for fast cutting
At just 1.2mm (3/64″) thickness, this 115mm cutting disc reduces contact area in the cut, so operators feel less resistance and can move through stainless steel, tool steel and structural steel faster than with thicker 1.6mm or 3.0mm wheels. The narrow kerf also saves material and reduces burrs, which lowers downstream grinding time.
High-strength structure for 13,300 RPM operation
High-purity alumina abrasive and a double-layer fiberglass mesh give the 4.5 inch cut off wheel the bending strength it needs to run safely at 13,300 RPM and 80 m/s on 115mm angle grinders, matching and in some cases exceeding typical industry benchmark values.
Tight dimensional tolerances for stable performance
Each 115×1.2×22.2mm disc is controlled to 115±0.15mm outer diameter and 1.20±0.03mm thickness, tighter than common ±0.3mm and ±0.08mm tolerances in the market. For distributors and OEM brands this means fewer out-of-spec pieces in a container and more consistent cutting feel across batches.
Designed for 115mm angle grinder discs
The 22.2mm (7/8″) bore fits standard 4.5 inch angle grinders from major brands, so distributors can list this SKU alongside existing 115mm metal cutting discs without asking their customers to change tools or flanges.
Industrial application range – where the 115×1.2×22.2mm disc fits best
Metal fabrication and profiling
This 4.5 inch cutting wheel is used for day-to-day cutting of stainless steel, tool steel and structural steel sections in fabrication shops where operators value a fast, light-feeling disc for repeated cuts on small and medium sections.
Pipeline and process pipe work
For oil and gas pipeline contractors and industrial pipe fabricators, the 115mm ultra-thin cut off wheel is suitable for bevel cuts, branch connections and trimming small-bore pipes where a 4 1/2 inch disc gives better access than larger diameters.
Construction rebar and section cutting
On construction sites the 4.5 inch cut off wheel is used for cutting rebar, I-beams and reinforcement where workers prefer a compact 115mm angle grinder for one-handed or overhead cutting and the 1.2mm profile keeps sparks and heat input under control.
Service and repair work
Maintenance teams use this 115mm cutting disc on bolts, brackets, welded attachments and small plates, where a thin, quick-cutting wheel shortens downtime compared to heavier 4 1/2 inch cutting discs.

Wholesale and OEM policy for 4.5 inch cut off wheel buyers
Qing Yang® positions this 4.5 inch cut off wheel wholesale SKU for distributors, importers and private label brands that need container-load volumes of 115mm ultra-thin cutting discs.
Export coverage – Existing shipments cover more than 20 industrial markets including the Middle East, Southeast Asia, Europe, the Americas and emerging regions such as South Africa and Brazil, so logistics routes and export documentation are already proven for 4.5 inch cut off wheel wholesale supply.
Flexible minimums for bulk orders – Standard minimum order quantity starts from 1,500 pieces for trial wholesale orders, with full 40HQ containers holding up to 72,000 pieces for large buyers.
OEM branding and colour options – We can supply your brand logo via laser engraving on the resin layer, match your colour ring, and design moisture-proof vacuum packs and export cartons in line with your current cutting disc range.
Volume-based pricing – The cutting wheel price decreases as annual volume increases, making it easier for distributors to keep a competitive 115mm cutting disc on their price list while maintaining margins.
Global supply and compliance
The 4.5 inch cut off wheel wholesale program is built around EN 12413 and BS safety standards, with destructive tests verifying bending strength, burst speed and RPM capability against these benchmarks before shipment. Each batch is packed in export-ready cartons and pallets sized for 20ft or 40HQ containers to keep handling simple at the distributor’s warehouse.
For buyers transitioning from other brands, we provide dimensional and tolerance data, performance comparison reports and sample packs so that the 115×1.2×22.2mm T41 disc can be qualified against existing 4.5 inch metal cutting discs before committing to full containers.
Preguntas frecuentes
This 4.5 inch wholesale cut off wheel uses a 115×1.2×22.2mm ultra-thin T41 design with high-purity alumina abrasive and double fiberglass mesh, giving faster cutting and lower resistance than many standard 4 1/2 inch cutting discs in the market.
It is manufactured with stricter tolerances and higher bending strength than typical benchmark values, so distributors can offer an industrial-grade 115mm cutting disc that feels lighter in the cut but still meets BS EN 12413 safety requirements.
Tighter outer diameter and thickness tolerances mean the 4.5 inch cut off wheels run more smoothly, produce more consistent kerf widths and generate fewer defective pieces in bulk orders.
With OD controlled to 115±0.15mm and thickness held at 1.20±0.03mm instead of the more common ±0.3mm and ±0.08mm, the wheel offers a more predictable cutting feel across different batches, which is important for OEM brands and large distributors.
The 4.5 inch 1.2mm cut off wheel is aimed at precision cutting on stainless steel, tool steel and structural steel sections in fabrication shops, pipeline projects and construction sites.
It is particularly suitable for bevel cutting on oil and gas pipelines, trimming I‑beams and rebar, and processing small and medium steel profiles where operators prefer a fast, low‑resistance 115mm disc on compact angle grinders.
For wholesale buyers and private label projects, the typical minimum order quantity starts from 1,500 pieces, with up to 72,000 pieces loaded in a 40HQ container for large-volume customers.
Standard lead time is around 18 working days, and the factory can supply OEM resin colours, laser-engraved logos and moisture-proof vacuum packaging so distributors can align this 115mm cutting disc with their existing product range.
