Solid carbide drill bits are the good choice due to stability, hole quality and cost efficiency. It can achieve IT8 tolerances while drilling at ideal penetration rate. The geometry can be flexibly designed specific to applications. Featured products in this catagory of Toolind include A Drill for carbon fiber composites, to eliminate  delamination and splintering. With CVD diamond, Toolind drilling tools has ex-long durability. Another featured product is micro drills, for making hole diameters as small as 0.03mm. Compared to carbide drill bits,  cobalt HSS drill bits drill at much slower speed, but are  good choice for  some applications, such as inclined entry drilling and cross hole drilling, where carbide tools are easy to break. It’s ideal choice for soft materials like plastic and wood. With correct geometry, machining parameters and good coating, both solid carbide drill bits and  cobalt HSS drill bits last very long without downtime. Re-grinding can be done by supplier or at shop easily. These make the use cost low.
