Janchi 7-1/4 inch 4T PCD Tip Hardie Fiber Cement Circular Saw Blade with 5/8-inch DMK Arbor

Premium blade for fibre cement and ultra-hard materials

The Janchi 7-1/4 inch blade with 4 polycrystalline diamond tipped teeth is engineered to handle fibre cement boards and other tough surfaces. Its PCD teeth are designed for durability, offering up to 60x longer cutting life than standard carbide blades, which can translate to fewer blade changes on demanding projects.

Designed for efficiency, this blade features an ultra-thin kerf of 1.8 mm and a laser-cut body. The combination minimizes waste and allows for faster, cleaner cuts. Anti-vibration features and expansion slots help keep chatter and dust to a minimum, so your work area stays a bit calmer and cleaner.
