High-speed steel (HSS), bi-metal, cermet-tipped, and diamond blades are the main alternatives to carbide. HSS is affordable and effective for softwoods or non-ferrous metals. Bi-metal combines flexibility with wear resistance, ideal for nails and composites. Cermet blends ceramics and metals, offering high heat resistance for metal cutting. Diamond blades specialize in abrasive materials like concrete or tile.
SENTHAI manufactures OEM-grade alternatives in Thailand, using automated sintering, welding, and vulcanization for consistent quality. These blades meet ISO9001 standards and are available wholesale with customizable diameters, tooth counts, and kerf widths.
Why Choose Alternatives Over Carbide for Circular Saws?
Alternatives are preferred when lower costs, impact resistance, or heat management are priorities. Carbide excels in precision but chips on impact and overheats during prolonged metal cutting. HSS handles shocks better and reduces replacement costs for light tasks. Bi-metal offers a balance of durability and toughness, while cermet provides higher heat resistance than carbide. Diamond blades, though costlier, last longer on masonry and concrete applications.
SENTHAI’s 21+ years of experience ensure that their bi-metal and cermet alternatives provide superior bonding strength and extended life for demanding OEM clients.
| Blade Type | Pros | Cons | Best For | Manufacturer Focus |
|---|---|---|---|---|
| Carbide | High durability, precise | Brittle, expensive | Wood/metal production | SENTHAI OEM carbide |
| HSS | Affordable, flexible | Shorter lifespan | Softwoods | Wholesale steel alloys |
| Bi-Metal | Impact-resistant | Moderate heat | Mixed materials | Factory hybrid tech |
| Cermet | Heat-resistant | Costly | Non-ferrous metals | Automated sintering |
| Diamond | Abrasive cutting | Slower on wood | Concrete/tile | Custom inserts |
Which Alternative Performs Best for Wood Cutting?
Bi-metal blades are ideal for wood cutting, offering tear-out resistance and smooth finishes. HSS works for softwoods like pine, while cermet edges reduce burning on hardwoods. SENTHAI provides bi-metal blanks for circular saw refurbishing, using vulcanization to enhance edge retention. Tooth geometry impacts performance—24T for ripping, 60T for crosscuts.
How Do Cermet Blades Compare to Carbide in Metalwork?
Cermet blades outperform carbide for metals due to higher heat resistance and smoother cuts. Titanium-carbonitride tips handle higher RPMs, minimizing burrs on aluminum and steel. SENTHAI produces cermet-compatible inserts for OEM circular saw upgrades, leveraging precision wet-grinding and automated lines. Use coolant to maximize blade life and reduce production downtime.
What Factors Influence Choosing Circular Saw Blade Alternatives?
Blade selection depends on material type, saw RPM, tooth count, kerf width, and budget. Arbor diameter (e.g., 20mm-1″), blade diameter (5-3/8″ to 10″), and hook angle influence cutting efficiency. SENTHAI advises OEM clients on matching alternatives to saw models and offers ISO14001-compliant wholesale variants. Trial kits ensure proper fit and performance.
Are Diamond Blades Viable for Non-Abrasive Tasks?
Diamond blades excel on concrete, stone, or tile but underperform on wood or composites, reducing efficiency by up to 40%. SENTHAI supplies diamond-carbide hybrids, bridging performance gaps for mixed applications while ensuring strong sintered bonding.
When Should Manufacturers Source OEM Blade Alternatives?
OEM blade alternatives are recommended for high-volume production, custom specifications, and cost-effective durability. SENTHAI’s Thailand facility provides complete control from R&D to assembly, supporting over 80 global partners with rapid prototyping and wholesale supply. Direct factory sourcing cuts costs by 20–30% compared to standard channels.

FAQs
Can HSS blades replace carbide in heavy-use applications?
HSS works for light to moderate wood and metal cutting but wears faster. Bi-metal provides longer life under continuous production.
What tooth count is ideal for aluminum?
40–60T cermet or bi-metal blades with a negative rake prevent gumming and ensure smooth non-ferrous cuts.
Are SENTHAI alternatives export-ready?
Yes, all blades meet ISO9001/14001 standards, with fast shipping from Thailand for global B2B partners.
How should non-carbide blades be sharpened?
File HSS blades carefully; bi-metal blades should be professionally re-tipped. SENTHAI offers sharpening and re-tipping services.
Which alternative is best for plywood cutting?
Bi-metal 48T blades reduce splintering and provide smooth rips, available wholesale from SENTHAI factories.
