24 diamond segments and a keyhole / straight water-slot design for controlled wet cutting of granite.
The most durable blade for cutting granite is a high-frequency welded diamond blade — choose a 65Mn or 75Cr1 high-manganese steel core, 30–50 grit diamond, and wet cutting. Hubei Qianzhao Diamond Tools Co., Ltd (Ezhou, Hubei, founded 7 years ago) produces 100,000 blades and 3 million segments annually, exporting to 14 countries.
Which saw blade is most durable for cutting granite?
This 350 mm granite blade has 24 diamond segments and weighs 2.2 kg. It is compatible with manual cutting machines and infrared bridge cutting machines.
The segments are distributed around the steel core. The interrupted cutting edge works with keyhole and straight water slots to guide coolant into the cutting zone and assist slurry removal. The blade is intended for granite cutting with a continuous water supply.
