Design principle of diamond round bottom cutter

The diamond round bottom knife is specially designed for relief processing of high hardness stone such as granite. The core principle is to balance wear resistance, carving accuracy, and curved surface forming effect with high hardness material and circular blade structure. The cutting tool adopts a diamond brazed cutting head, relying on the ultra-high hardness of diamond to effectively resist the strong abrasion of granite, greatly improving the service life of the tool. Paired with a high-strength alloy handle, it ensures overall rigidity and is not easily twisted or broken during processing, making it suitable for high-speed stone carving operations.
The cutting tool adopts a unique blade design with a taper and a rounded bottom arc. The curved blade tip has no sharp edges and can smoothly polish relief surfaces, curves, and transition surfaces, eliminating carving steps and knife marks, ensuring the smooth and delicate texture of the work. Equipped with a spiral chip groove and a reasonable trailing angle of the cutting edge, it can quickly export hard stone chips, reduce friction and heat accumulation between the cutting tool and the stone, and avoid overheating and damage to the cutting edge. Simultaneously optimizing the ratio of handle diameter to blade length, suppressing machining vibration, and effectively solving problems such as distortion of stone relief surfaces, rough patterns, and easy tool breakage.
