High Performance 2 Flutes Carbide Twist Drill

solid carbide twist drill General machining:
1.Wide applications, for high efficient machining of various materials P (steel), M (stainless steel), K(cast iron), 
and S (heat-resistant alloy).
2.Optimized flute structure and corrugated cutting edge with outstanding sharpness and strength ensure 
unhampered chip flow.
3.140° point angle reduces the feed force of drilling in the initial stage, achieving perfect self-centering capability 
and improving quality of hole machined.
4.Nano-structured TiAlN coating improves thermal hardness and avoids built-up edge
 
Grade introduction for solid carbide drill tools:
Coated grade
KDG303
Ultra-fine carbide substrate with high strength,toughness and wear resistance, in combination with nano-structured 
nc-TiAlN coating aiming at optimizing drilling operations, makes sure the tools have very high toughness and hardness. 
Unique coating technology gives the tools smooth surface and excellent wear resistance, and outstanding thermal 
stability and chemical stability provide effective protection for the cutting edge.
Uncoated grade
YK20F
Ultra-fine grain carbide substrate with high hardness, outstanding wear resistance, and long tool life.
YK30F
Ultra-fine carbide substrate with high strength, toughness and wear resistance gives the cutting edge perfect strength.
