Reasons for the design of depressed center cut off wheel:

The depressed center cut off wheel has a "cymbal" shape, that is, it is thin in the center and thicker at the edges, like a small cymbal. The main purpose of this design is to optimize the performance and effect of the cutting process by adjusting the structure of the cutting blade. Depressed center cut off wheels have the following features:

1. Reduce heat accumulation: The design of depressed center cut off wheel helps to distribute the heat generated during cutting more evenly, avoiding excessive heat accumulation during the cutting process. Overheating may cause the metal workpiece to deform or the cutting blade itself to wear too quickly.
2. Improve stability: Depressed center cut off wheels reduce vibration during cutting through their design, improving the stability and accuracy of the cutting process.
3. Improve cutting efficiency: Due to the advantages in structural design, depressed center cut off wheels can effectively improve cutting efficiency and reduce cutting force when performing high-speed cutting, making work easier.

The difference between T42 cut off wheel and T41 cut off wheel:

1. Flat cut off wheel (T41): Traditional flat cutting discs are simple in design, with uniform thickness throughout the cutting disc, suitable for general metal and stainless steel cutting tasks, and work more stably, but may cause problems such as overheating and large vibration during high-load operations or precision cutting.
2. Depressed center cut off wheel (T42): Due to its depressed center design, it can reduce workpiece deformation caused by heat accumulation, and is particularly suitable for precision cutting and thin material cutting (such as thin steel plates, aluminum alloys, etc.), efficient cutting, especially under high load, can reduce overheating, reduce vibration, and provide higher stability and cutting accuracy.

T42 depressed center cut off wheel is widely used in metal processing, construction engineering, automobile repair and other fields that require fine cutting. It is suitable for cutting various metal materials, including steel, stainless steel, aluminum alloys and other carbide materials, especially when cutting thin plates or precision parts.
