Qing Yang® manufactures 6 inch cutting discs (150mm diameter, T41 flat profile) for hardware distributors, angle grinder accessory importers, and OEM buyers requiring factory-direct bulk supply. At 150mm, this is the compact end of the angle grinder cutting disc range — rated to Max 10,200 RPM and 80 m/s, which is the highest rated speed in the Qing Yang® cut-off wheel line, reflecting the smaller disc radius and the higher rotational speeds a 6 inch angle grinder operates at.
The T41 flat geometry and ultra-thin profile minimize kerf width and heat input at the cut face — the profile specified by fabricators working on light-gauge metal, thin-wall tube, rebar ties, and confined-access cuts where a larger 7 inch or 9 inch disc cannot reach.
Product Advantages
10,200 RPM rated speed for 6 inch angle grinders
The 150mm cutting disc is engineered to match the higher no-load RPM of 6 inch angle grinders. At rated 10,200 RPM / 80 m/s peripheral speed, the disc maintains abrasive surface velocity equivalent to larger diameters operating at lower RPM — delivering the same cutting energy in a compact format. EN 12413 burst speed certification requires passing a 1.5× speed test at 15,300 RPM.
Ultra-thin kerf for light-gauge and confined-access cutting
The T41 flat profile and thin abrasive layer minimize contact area at the cut line, reducing heat generation per cut on thin-wall stainless tube, sheet metal, and small-diameter rebar. This matters for applications where heat tinting on inox surfaces or distortion of light-gauge steel sections is a rejection criterion.
Double fiberglass mesh reinforcement
Two-layer woven glass fiber matrix maintains structural integrity at full rated speed. The reinforcement layer resists lateral flex during angled or confined cuts — the operating condition most common with 6 inch discs used in tight spaces.
22.2mm universal arbor bore
Standard 22.2mm (7/8 inch) center bore fits all 6 inch angle grinders with a 22.2mm spindle — the global market standard for this disc size across European, Asian, and North American equipment.

Thickness note: Please contact us to confirm available thickness options (typically 1.0mm, 1.2mm, or 1.6mm for 150mm diameter). Thinner profiles reduce heat input and kerf width; thicker profiles increase disc life on higher-contact applications. We can adjust the formula for your target market specification.
Cutting Applications
Light-gauge stainless steel tube and sheet metal
The combination of 150mm diameter and thin abrasive profile makes the 6 inch cutting disc the preferred size for cutting small-diameter stainless steel tube (OD under 50mm), sheet metal blanks, and thin-wall rectangular hollow sections. The smaller disc diameter reduces the arc length in contact with the workpiece at any point, which naturally limits heat accumulation on heat-sensitive inox.
Rebar and tie wire in construction
6 inch cutting discs are widely used on construction sites for cutting rebar and tie wire in confined spaces — between formwork panels, in beam cages, and inside column reinforcement — where a 9 inch or larger disc cannot maneuver safely. The 10,200 RPM rating maintains cutting speed even on high-carbon rebar grades.
Automotive bodywork and thin steel profiles
Sheet metal cutting in automotive bodywork, door frame fabrication, and exhaust system repair requires a disc small enough to work in restricted access areas. The T41 flat profile cuts cleanly through 1–3mm steel sheet without the flange clearance issues of a T42 depressed-center disc.
Bolt and fastener cutting in maintenance
Cutting corroded bolts, anchor rods, and threaded fasteners in maintenance and demolition applications is one of the highest-frequency uses for 6 inch cutting discs. The compact disc size reduces the risk of contact with adjacent components and allows the operator to work in a more controlled position.
Application boundary: This T41 flat disc is designed for metal cutting. Do not use on concrete, stone, ceramic tile, or masonry — those applications require a different abrasive bond system.

Frequently Asked Questions
The 150mm T41 cutting disc is designed for 6 inch angle grinders with a 22.2mm (7/8 inch) spindle bore, rated to a minimum of 10,200 RPM no-load speed. Always verify that the angle grinder’s rated no-load RPM meets or exceeds 10,200 RPM — a 6 inch disc mounted on an underpowered grinder with insufficient RPM will cut slowly and wear unevenly. For 6 inch grinders rated below 10,200 RPM, contact us for a lower-RPM rated disc specification.
The 6 inch (150mm) disc runs at a higher maximum RPM (10,200 vs. 8,500 for a 7 inch disc) to achieve the same 80 m/s peripheral cutting speed from a smaller radius. In practice, the 6 inch disc is specified for confined-access cuts, light-gauge sheet metal, small-diameter tubing, and applications where a 7 inch disc is physically too large to maneuver. The 7 inch disc covers standard flat-surface and structural steel cutting where reach and disc life per unit are the priority. If your customers work across both applications, stocking both sizes from a single OEM source — with matching label branding — reduces procurement complexity.
Standard MOQ is 100,000 pieces for full private label orders including custom blotter printing, branded inner retail box, and master export carton with your barcode. Mixed-container loads combining 6 inch with other disc sizes are accepted within a single 40ft FCL. Standard production lead time is 15–25 days after order confirmation and deposit. Sample packs for pre-order quality verification are dispatched within 5 business days.
Yes. The aluminum oxide abrasive formula used in this disc is free of iron, sulfur, and chlorine — none of which are introduced to the cut surface during grinding. At the thin disc thickness and 150mm diameter, the contact arc at the cut face is smaller than with a larger disc, which limits heat input per cut. For food-grade or architectural inox where heat tinting causes surface rejection, maintain full rated RPM throughout the cut and avoid dwelling in the kerf. We can supply dedicated inox-only disc batches on request if your customer requires separation from mild steel cutting stock.
