1. Twist drills are cutting tools and are mainly used for metal drills, so it is very important to control the speed
2. The recommended speed of this product is 100-800R/MIN. The larger the diameter, the slower the speed requirement.
3. M35 cobalt-containing high-speed steel twist drill is HRC64-66 degree in India, suitable for drilling metal with a degree of <38, and cannot drill quenched metal
4. When working with manual drills, pay attention to adjusting the speed. If the speed is too fast, the drill will be easily damaged.
5. This product should not be knocked during use, the work needs to be fixed, and the work swing will break the drill bit during operation
6. For metals with high hardness and many impurities, the speed is slower than that of normal drilling, and the cooling effect is better.
7. When processing products with large thickness, if there is abnormal discharge, please remove the debris in time
8. This product can be used in grinding, the company can provide technical support for sharpening
