PATIKIL 9.7mm Drill Bit, Carbide Twist Jobber Bits Straight Shank 130° for Drilling Hard Metal Alloy Steel Stainless Steel Titanium Alloys - 1 Pack

• PACKING LIST: 1 pack of drill bits in 9.7mm cutting diameter, 40mm/1.57 inch flute length, 75mm/2.95 inch overall length, 130° Point Angle
• FEATURE: Cemented Carbide twist drills have become the preferred tool for industrial drilling due to their exceptional performance. With ultra-high hardness, they can effortlessly machine difficult-to-cut materials like hardened steel and stainless steel. Their wear resistance is 5-10 times that of HSS drills, significantly extending service life. The excellent thermal stability supports cutting speeds 2-50 times faster than conventional drills
• 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.
• INSTRUCTION: The twist drill should be at a 90° angle to the workpiece. When drilling different materials, the drilling speed needs to be adjusted. The harder the material, the lower the drilling speed should be. Adjusting the speed can improve cutting efficiency, extend tool life, and reduce material damage.

Cemented Carbide twist drills have become the preferred tool for industrial drilling due to their exceptional performance. With ultra-high hardness, they can effortlessly machine difficult-to-cut materials like hardened steel and stainless steel. Their wear resistance is 5-10 times that of HSS drills, significantly extending service life. The excellent thermal stability supports cutting speeds 2-3 times faster than conventional drills. Titanium Aluminum Silicon Nitride Coating: Composed primarily of Ti (titanium), Al (aluminum), Si (silicon), and N (nitrogen), this nano-composite coating significantly enhances the hardness, wear resistance, and high-temperature stability of twist drills. It effectively prevents high-temperature oxidation while reducing the friction coefficient by 30%, substantially minimizing chip adhesion during cutting and ensuring stable, efficient machining processes. 130° Point Angle: A characteristic feature of carbide drills, which provides enhanced cutting stability and self-centering capability through increased contact area between drill point and the workpiece √APPLICATION Carbide twist drills 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. √PACKING LIST: -Cutting Diameter: 9.7mm -Shank Diameter: 9.7mm -Flute Length: 40mm/1.57 inch -Total Length: 75mm/2.95 inch -Package Content: 1pcs x Drill Bit √NOTE: During the machining process, friction between the drill bit and the material generates significant heat. Using coolant effectively reduces the temperature, preventing tool overheating and extending the lifespan of the drill bits.
