TCT Saw Blade for Steel: Tooth Count and Size Selection

Choose the right TCT blade for steel by matching tooth count and diameter to your saw and cut quality needs. This guide explains trade-offs between speed and finish.
Quick answer
For general-purpose steel cutting on a standard miter or circular saw, choose a 10-inch 52-tooth TCT blade. For smoother finishes on thin-wall or sheet metal, step up to an 80-tooth blade. For larger production cuts on a dry-cut saw, a 14-inch 120-tooth blade delivers the best edge quality.
Why tooth count matters for ferrous metal
More teeth produce a smoother finish but cut slower and generate more heat. Fewer teeth cut faster but leave a rougher edge. For steel, the TCG (Triple Chip Grind) geometry on these blades helps reduce burr formation regardless of tooth count.
Size compatibility with your saw
Not all saws accept every blade diameter. A 5-3/8-inch blade fits compact circular saws and trim saws, while a 10-inch blade is standard for most miter saws and table saws. The 14-inch blade requires a low-RPM dry-cut saw specifically designed for that size. Always check your saw's arbor size and RPM rating before buying.
Decision rules for selecting a TCT blade for steel
- Saw type: Use a 5-3/8-inch or 10-inch blade on portable circular saws and miter saws. Use a 14-inch blade only on a low-RPM dry-cut saw rated for that diameter.
- Cut quality vs. speed: Choose a 52-tooth blade when you need a reasonable finish and fast cuts on structural shapes. Choose an 80-tooth blade when you want a smoother edge and can accept a slower feed rate.
- Material thickness: For thin-wall tubing or sheet metal, an 80-tooth or 120-tooth blade reduces burring and vibration. For thick bar stock or beams, a 52-tooth blade clears chips more efficiently. If you frequently switch between thick and thin steel, consider owning both a 52-tooth and an 80-tooth blade.
Product facts
- 10" 52-tooth Tct Saw Blade For Steel & Ferrous Metal: 10-inch 52-tooth TCT blade with TCG geometry for steel and ferrous metals The 52-tooth count balances cutting speed and finish, making it a versatile choice for structural steel, angle iron, and tubing on a standard miter saw.
10" 52-tooth Tct Saw Blade For Steel & Ferrous Metal - 10" 80-tooth Tct Saw Blade For Steel & Ferrous Metal: 10-inch 80-tooth TCT blade with TCG geometry for steel and ferrous metals The higher tooth count prioritizes edge quality, so it is the better option when you need a nearly burr-free cut on thin-wall or sheet metal.
10" 80-tooth Tct Saw Blade For Steel & Ferrous Metal - 14" 120-tooth Tct Saw Blade For Steel & Ferrous Metal: 14-inch 120-tooth TCT blade for steel and ferrous metals on compatible low-RPM dry-cut saws The large diameter and high tooth count make this blade ideal for production cutting of beams and heavy stock where finish quality is critical.
Which blade fits your job?
Best for
- General-purpose steel cutting on a standard miter saw: 10-inch 52-tooth blade
- Smooth, nearly burr-free cuts on thin-wall or sheet metal: 10-inch 80-tooth blade
- Production cutting of beams and heavy stock on a dry-cut saw: 14-inch 120-tooth blade
Not for
- High-speed cutting where rough edges are acceptable – consider a 52-tooth blade instead of 80 or 120
- Saws that cannot accept a 14-inch blade – stick with 10-inch or 5-3/8-inch diameters
