Material: 4341 high speed steel, made of high speed steel (HSS), high hardness, rust-proof, long service life. Size: M3x0.5, M4x0.7, M5x0.8, M6x1, M8x1.25, M10x1.5. 6 size combinations to perfectly meet your different needs. The sharp drill bits can resist slight induction wear after induction quenching treatment, ensure higher punching speed and improve work efficiency. Drilling, tapping, deburring and countersinking can be done at one time, saving processing steps and time costs, and improving work efficiency. 6 steel drill bits, suitable for drilling wood, plastic, thin copper, aluminum and other soft metals (5-6mm), not suitable for hard materials (such as steel plates). When drilling, it is necessary to inject water at the same time to cool the drill bit. This will help you add value to your practice.
