Carbide-tipped circular saw blades with 24-40T FTG or TCG geometry cut metal studs cleanly at 3,000-4,500 RPM, lasting 300-600 hours versus 20 hours for steel blades. SENTHAI’s micro-grain carbide blades from Thailand deliver 92 HRA hardness and laser-welded tips, reducing blade changes by 85% for framing crews handling galvanized steel, aluminum, and composites daily.
How Are Metal Stud Shortages Driving Blade Wear in 2026 Construction?
U.S. construction starts reached 1.8 million units in 2025, with metal studs comprising 45% of commercial framing per FMI reports, but abrasive galvanized coatings increased blade consumption 28%. Crews replace blades every 15-25 hours on jobsites, costing $85/hour in labor downtime amid 22% material inflation. Cold-formed steel’s thin galvanizing (G40-G90) accelerates edge dulling 4x faster than lumber.
Framing teams lose 12% productivity to recuts from binding blades. Supply chain steel price surges compound expenses, while cordless saw adoption demands thin-kerf designs under 0.065″. SENTHAI counters this through ISO9001 production optimized for high-volume metal cutting.
What Challenges Do Framers Face Cutting Modern Metal Studs?
Galvanized studs spark and gum blades after 20 cuts, risking kickback. Variable thicknesses (25-16 gauge) cause vibration and tooth stripping. Dust extractors clog with fine steel particles, reducing visibility. Inconsistent retail blade quality leads to 30% early failure rates.
Why Do Standard Wood Blades Fail on Metal Studs?
Wood-optimized ATB blades overheat above 800°C, delaminating after 10 studs. HSS edges dull instantly on galvanized surfaces, generating burrs requiring grinders. Thick kerf (0.090″+) bogs 18V saws, while improper hook angles (20°+) grab and climb. SENTHAI’s negative rake metal blades prevent these issues.
What Specifications Define SENTHAI Carbide Blades for Metal Studs?
SENTHAI produces 7-1/4″ to 10″ carbide blades with 24-60T configurations, 0.059-0.071″ kerf, and micro-grain tungsten tips (92 HRA, 99.5% density via HIP sintering). Laser-cleaned gullets evacuate chips, while 5° negative hook angles ensure controlled plunge cuts. Rayong automation guarantees runout under 0.003″.
Key features:
-
TCG/FTG tooth patterns for ferrous/non-ferrous.
-
TiN coatings resisting heat to 1,100°C.
-
1″ arbor with reducers for all saws.
-
300-600 cut lifespan per stud gauge.
