Qing Yang® builds this 4 inch cutting wheel in a 107×0.8×16mm T41 specification — a disc that fits the same compact angle grinders as the standard 100mm range but cuts at 0.8mm kerf width, roughly a third narrower than a conventional 3.0mm 4 inch disc. That difference matters most when you are working on thin-walled stainless tube, small profiles or any job where you need the cut line tight and the heat input low. This is not the same disc as our 100×1.2×16mm wholesale SKU; the 107mm outer diameter and the 0.8mm section give it a different cutting character and a different buyer profile.
Performance advantages of the 107×0.8×16mm ultra-thin disc
0.8mm kerf for the cleanest cut in the 4 inch range
At 0.8mm thick, this disc removes less material per cut than any other 4 inch cutting wheel we manufacture. The narrow kerf translates to lower cutting force on the grinder, less friction heat at the cut edge and a cleaner burr-free finish on stainless steel and alloy steel — which typically means less time spent grinding the cut face before welding or assembling.
107mm outer diameter with standard 16mm bore
The slightly larger 107mm OD compared with a 100mm disc gives fractionally more cutting depth while keeping the same 16mm arbor fit and standard guard clearance on any 4 inch angle grinder. Operators using Makita GA4030 or equivalent compact tools can swap straight in without adapters.
Double fiberglass mesh at 80 m/s
The disc is reinforced with two layers of fiberglass mesh, giving the burst resistance needed to run safely at 80 m/s on 4 inch grinders. This meets EN12413 requirements and keeps the structure intact even when cutting edge-on into harder steel sections.
Vacuum-formed abrasive distribution
Vacuum hot-press forming ensures the aluminium oxide grains are distributed evenly through the bond layer. Combined with a flatness tolerance of ≤0.1mm, this means the disc cuts straight and consistent batch after batch — which is important when a buyer is sourcing at volume and cannot afford variability between production runs.
Industrial applications for the 107×0.8×16mm disc
Thin-walled tube and small diameter pipe
The 0.8mm profile is the right choice for cutting thin-walled stainless steel and alloy steel tubes where a wider kerf would cause the tube wall to deform or leave an oversized gap. HVAC contractors, hydraulic fitting manufacturers and precision tube fabricators use this specification specifically because the cut-to-cut repeatability is better than with thicker discs.
Tight-clearance mechanical maintenance
When a bolt, bracket or small weld needs to be cut in a confined machine bay or between installed components, a 107mm disc on a compact 4 inch grinder gets into gaps that a 115mm or 125mm tool simply cannot reach. The 0.8mm kerf also reduces the risk of accidentally damaging adjacent material in tight spaces.
Precision cutting of alloy and tool steel profiles
Fabricators working on alloy steel sections, small angles and flat bars use the 107×0.8×16mm disc when the dimensional accuracy of the cut piece matters — for example when cutting to length before CNC machining. The low resistance and stable kerf width reduce the chance of the disc wandering off the scribed line.
Construction site repair and rebar trimming
On active construction sites, the compact 4 inch grinder with the 107mm disc is a practical tool for trimming rebar ends, cutting stirrups to adjusted lengths and removing tack welds without disturbing adjacent ironwork.

OEM and direct supply from the 4 inch cutting wheel manufacturer
Qing Yang® operates as the source manufacturer for this 107×0.8×16mm disc, which means buyers deal directly with the production facility rather than a trading company. For distributors who want to build their own cutting disc brand in the 4 inch segment, we support full OEM customisation: label design in your own brand colours, laser-engraved logo, resin layer colour options and export carton layout that matches your existing product range.
The 107mm specification occupies a distinct niche from the 100mm disc and is particularly well received in markets where precision cutting of thin-walled tube and small profiles is common, including HVAC supply chains in the Middle East and precision fabrication distributors in Southeast Asia and Europe. Buyers who want to carry both a general-purpose 100mm wholesale SKU and a specialist 0.8mm ultra-thin SKU can source both from the same production base, which simplifies supplier management and keeps lead times consistent.
الأسئلة الشائعة
The 0.8mm thickness is the narrowest profile available in the 4 inch cutting disc category. Compared with a standard 1.2mm or 3.0mm 4 inch wheel, it removes roughly a third less material per cut and generates noticeably less friction heat at the cut edge, which matters most when you are working on thin-walled stainless steel tube, small alloy steel profiles or any job where dimensional accuracy and surface quality at the cut face are important.
The slightly larger 107mm outer diameter also gives marginally more cutting depth than a 100mm disc while keeping the same 16mm bore and standard guard compatibility on 4 inch angle grinders, so operators get a bit more reach without changing tools.
This disc is designed for stainless steel, alloy steel and tool steel where a clean, narrow kerf matters. It performs particularly well on thin-walled stainless tube used in HVAC, hydraulic fittings and precision piping, and on small angle, flat bar and profile steel sections where a wider kerf would leave an oversized gap or cause the workpiece to deform.
It is also a practical choice for mechanical maintenance and tight-clearance repair jobs, where the compact 107mm diameter combined with the low-resistance 0.8mm profile lets an operator cut in confined spaces that a 115mm or 125mm disc cannot access.
Sourcing directly from the manufacturer rather than a trading company means specifications are controlled at the production stage rather than filtered through an intermediary. For the 107×0.8×16mm disc this matters because 0.8mm tolerances are tighter than those for thicker discs — a small variation in thickness or flatness shows up more clearly in the cutting feel and kerf width.
Our internal process uses vacuum hot-press forming, which distributes the aluminium oxide grain evenly through the bond layer and keeps the disc flatness tolerance to ≤0.1mm. Distributors and OEM buyers who have tested multiple supply sources typically find this consistency reduces the rate of callbacks and rejects across production batches.
We support full OEM and private label projects for this SKU, including custom label artwork, resin layer colour, barcode format and retail or export carton layout. The 107×0.8×16mm disc can be packaged to match your existing 4 inch cutting disc line or presented as a standalone ultra-thin specialist product, depending on how you position it in your market.
Lead times and minimum quantities are sized to suit both regional trial orders and full container shipments, so distributors testing a new ultra-thin SKU alongside their existing range can start at a manageable scale before committing to high-volume production.
