About this item

• PACKING LIST: 10 pack of drill bits in 2.2mm cutting diameter, 20mm/0.79 inch flute length, 40mm/1.57 inch overall length, 130° Point Angle
• FEATURE: Cemented carbide twist drills are widely used in industrial drilling for their strong performance. They offer high hardness, high wear resistance and thermal stability, enabling effective machining of difficult-to-cut materials such as hardened steel and stainless steel, they are designed for
• APPLICATION: Carbide twist drills with titanium aluminum silicon nitride coating are suitable for machining high-hardness materials due to their ultra-high hardness and heat resistance, including hardened steel, alloy steel, stainless steel, titanium alloys, cast iron, hard plastics, and wood.
• 130° POINT ANGLE: A characteristic feature of carbide drills, which provides enhanced cutting stability and self-centering capability through increased contact area between the drill point and the workpiece.
• NOTE: Although it can machine very hard materials, cemented carbide is prone to fail in unstable working conditions or situations prone to vibration. In practical applications, it is essential to use a rigid machine tool and ensure high-precision drill chuck clamping to minimize vibration. Appropriate cutting parameters (particularly feed rate) must also be selected to avoid any form of impact load.
