Description of πͺ Cobalt General Purpose Deg Split Drilling: Cutting-Edge Efficiency for All Drilling Needs
βοΈ COBALT DRILL BIT DIMENSION:1/2"(Diameter) x 4-1/2"( Flute Length) x 6"(Overall Length). βοΈ COBALT MATERIAL: HSS(M35) Cobalt Steel is the premium material with high hardness and red hardness to enable long drilling life and fast drilling performance. βοΈ SURFACE TREATMENT: The Gold Oxide Ember finished surface treatment strongthen the hardness of drill bit body to ensure the long drilling life and better drilling performance. βοΈ SPLIT POINT ANGLE 135 DEG.: No center punch is needed- the aggrevsive 135 deg. Split Point quick-cutting points are self- centering and penetrate quickly with less pressure. will not "walk" or"wander". βοΈ APPLICATION: Best used for drilling into light-gauge metal, high-carbon steel, aluminum and alloy steel, cast iron, stainless steel and titanium.
