OSG AD&ADO hard alloy drill bit series:
Corresponding to a wide range of processing materials, AD&ADO series carbide drills adopt EgiAs coating to improve wear resistance, heat resistance, and optimize toughness coatings to achieve long life and stable life. ADO internal cooling drills are most suitable for various hole depth styles, large chip pockets that improve chip evacuation, and the design of the middle blade, which can improve the stability when processing deep holes. According to the type, two blade shapes are used: corrugated blade shape and straight blade shape. 3D\5D\8D is a corrugated blade shape with features: low resistance, stable torque to achieve long life, small chips and easy to break. 10D\15D\20D\25D\30D is a straight blade shape. Features: For deep hole drills with a long overhang, a design that takes into account the strength of the blade tip and low resistance.
