TWIN-TOWN 7-1/4 in 6-Tooth PCD Saw Blade with 5/8 in Arbor for Hardie Fiber Cement

Overview

The TWIN-TOWN 7-1/4 inch 6-Tooth Polycrystalline Diamond Tipped (PCD) saw blade is engineered for demanding fibre cement work and tough surface materials. Its design centers on a very thin kerf, allowing faster cuts with less resistance and reduced waste. The blade is built to stay sharp longer, thanks to six PCD tips that deliver consistent performance across multiple cuts. Notably, you can expect a blade life that, in testing scenarios, reaches up to 50 times longer than standard carbide blades, giving you more productive work intervals between replacements.

Designed for professional results, this blade pairs a 7-1/4 inch diameter with a 5/8 inch arbor and a maximum operating speed of 8500 RPM. It is compatible with fibre cement boards and ultra-hard materials, including Hardie Plank, Eternit, MDF, and Corian, making it a versatile choice for renovation, siding, and finish work where precision matters.

Key benefits

• Performance thin kerf design of 0.071 inches enables fast cuts and minimizes material waste.
• Specially designed for cutting fibre cement boards and ultra-hard materials such as Hardie Plank and Eternit, with additional suitability for MDF and Corian.
• Anti-stick coating helps reduce rust and corrosion, contributing to smoother operation over time.
• Six polycrystalline diamond tipped teeth provide at least 50x longer cutting life than standard carbide blades.
• 7-1/4 inch diameter with a 5/8 inch arbor; MAX RPM 8500, optimized for compatible circular saws.

Applications and use cases

• On-site fibre cement installations, such as Hardie Plank siding, where clean, fast edges are valued.
• Renovation projects involving Eternit or other ultra-hard boards, MDF panels, or solid surface materials like Corian.
• Edge finishing and precise cross-cuts on tough boards where waste reduction and edge quality matter.
• Projects requiring consistent performance across multiple cuts without frequent blade changes.

What to expect on the job

Users often notice smoother edge quality and reduced resistance during cutting, thanks to the blade’s thin kerf and robust PCD teeth. The anti-stick coating helps maintain a cleaner cut path, while the long blade life minimizes downtime for replacements. When paired with the right saw and feed rate, the blade can support efficient workflow on both new builds and remodeling tasks.

Whether you’re a contractor or a DIY enthusiast tackling fibre cement panels, this blade offers a practical balance of speed, precision, and durability. It may help you achieve consistent results while keeping waste to a minimum, without promising guaranteed outcomes in every situation.
