QC-44 Saw Blade

The QC-44 is a 44-Tooth M35 Cobalt orbital saw blade (68mm diameter) featuring a premium AlTiN (Aluminum Titanium Nitride) coating. Specifically designed for Schedule 10 stainless and medium-wall tubing (up to 3mm), its aggressive tooth pitch allows for rapid chip evacuation in heavier applications. 100% compatible with Orbitalum GF/GFX and Axxair machines with a standard 16mm arbor.

QC-44 AlTiN Coated Orbital Saw Blade (44T)

The Heavy-Wall Workhorse for Schedule 10 Stainless & Tough Alloys

The QC-44 is the industrial solution for fabricators cutting Schedule 10 stainless steel and heavy-walled pipe. While finer blades (72T+) often clog and overheat in thicker materials, the 44-tooth geometry of the QC-44 provides the necessary “gullet space” to evacuate large chips quickly, preventing heat buildup and blade failure.

Why the QC-44 Outperforms on Heavy-Wall Pipe:

• AlTiN Thermal Shield: The Aluminum Titanium Nitride coating provides a high-hardness surface that excels in dry-cutting environments. It keeps the heat in the chip and away from the M35 cobalt steel core, extending tool life by up to 40% over uncoated blades.
• Aggressive Chip Evacuation: The 44-tooth pitch is optimized for wall thicknesses between 0.9mm and 3.0mm (0.035” – 0.120”). This prevents “chip welding,” a common issue when cutting 316 stainless with higher tooth counts.
• M35 Cobalt Metallurgy: Manufactured with 5% Cobalt for maximum “red hardness,” ensuring the cutting edges remain sharp even during extended heavy-duty runs.
• Precision Grind: Specifically ground for a clean, square cut on 2” to 4” pipes, making it the perfect choice for process piping prep before orbital welding.
