Why Circular Saws Are the Core of Any Power Tool Line
Circular saws are the highest-volume cutting tool category globally. For brands building a power tool line, circular saws are typically the entry point — high demand, multiple price tiers, and a straightforward path to OEM customization. China accounts for the majority of global circular saw production, with the Zhejiang province supply chain producing everything from entry-level corded models to professional brushless cordless platforms.
We manufacture circular saws at our Ningbo facility alongside our sliding miter saws and jigsaws, using the same vertically integrated production model. Here is what OEM buyers need to know about sourcing circular saws from China.
Circular Saw Categories: What Buyers Are Sourcing
| Category | Blade Size | Power Source | Typical Market |
|---|---|---|---|
| Compact cordless | 115–150mm | 20V battery | DIY, light trade |
| Standard cordless | 165–185mm | 20V / 40V battery | Contractor, pro |
| Corded workshop | 165–210mm | 120V / 230V | Workshop, emerging markets |
| Worm drive | 185–210mm | 120V | US framing/construction |
Key Specifications to Specify in Your RFQ
Blade size and arbor diameter: The most fundamental spec. 165mm (6-1/2") is the global standard for framing circular saws. 115mm and 135mm compact models are growing rapidly in the cordless segment. Always specify arbor diameter — 20mm is standard for European models, 5/8" (15.875mm) for North American.
Bevel capacity: Standard is 0–45°. Dual-bevel models (left and right) are a premium feature. Most OEM circular saws are single-bevel left-side tilt.
Motor type: Brushed universal motors dominate the corded entry-level segment. Brushless (BLDC) motors are standard on all serious cordless models and are increasingly used in corded premium models. Brushless motors run cooler, last longer, and deliver 15–20% more cutting capacity per battery charge. Our 115mm Cordless Circular Saw uses a 20V brushless motor with 3,700 rpm no-load speed.
Base plate material: Stamped steel for entry-level; magnesium alloy for professional grade. Magnesium saves 200–400g of tool weight and improves rigidity over the cut line — relevant for branding to the professional trade segment.
Brushless vs Brushed: The Commercial Decision
From a brand positioning standpoint, whether you lead with brushed or brushless determines your price tier. Brushed corded circular saws are the volume play — lower cost, straightforward manufacturing, well-understood by buyers globally. Brushless cordless saws are the margin play — higher ASP, growing market share in Europe and North America, and the product specification that wins trade account listings.
For a new brand, the practical recommendation is to launch with a corded brushed model for volume and a cordless brushless model for brand positioning. The two products serve different channels and different buyer motivations without cannibalizing each other.
Certifications by Market
Circular saws exported to the EU require CE marking under the Machinery Directive and EMC Directive. GS certification (TÜV or equivalent) is effectively mandatory for German retail. UL or ETL certification is required for the US market at most retail partners. Our circular saw line carries CE, GS, and UL across the range.
For cordless models, the battery pack requires additional certifications: UN38.3 for transport and IEC 62133 for cell safety. These are in addition to the tool certifications and must cover your specific battery configuration.
OEM Pricing and MOQ

Frequently Asked Questions
What is the standard blade size for OEM circular saws sold in Europe?
165mm (6-1/2") is the dominant size for general-purpose saws in Europe and Australia. 210mm models are used for heavy structural timber work. Compact 115mm models are growing in the cordless DIY segment across all markets.
Can I order both corded and cordless versions of the same model?
Yes — we produce corded and cordless variants of the same platform where the chassis design allows. This enables cross-platform spare parts management and a consistent brand look across your catalogue.
Does the circular saw come with a blade included?
Standard OEM orders include one TCT (tungsten carbide tipped) blade. Blade tooth count and kerf width are configurable. We also supply replacement blades on a separate schedule if needed for your accessory programme.
How do I qualify a Chinese circular saw factory?
Ask for certificate documents with model-specific scope, request factory audit access, and confirm whether motors are manufactured in-house. Our factory sourcing guide covers the vetting checklist in detail.
