7. Carbide (tungsten steel) material, with high hardness, high wear resistance,  anti-bending, anti-damage

8. Processing range : Applicable to the circuit board, electronics, SMT, mold, metal processing, communications

9. Drill bit chip space: chip resistance is small, smooth chip removal, drilling heat a small, reduce drilling

10. Cutting edge strictly symmetrical: conducive to efficient cutting, to avoid drilling offset

11. Bbased on customer application tool design: drill variety, to meet the needs of different applications. Drill all parameters, such as core thickness, core taper,

12. Long life, it can drill 2000-5000 pcs under normal working conditions, also can return grinding 4-5 times

Feature :

As a result of the use of nano-technology and advanced grinding technology, drill bit cutting edge is more sharp than before, can reduce the cutting force, reduce the drilling rate, improve the quality of the hole wall;
