SDF-M Series General Purpose Internal Cooling Carbide Drill for Stainless Steel with DP Coating
1. Product Design and Material Selection
The SDF-M series general purpose internal cooling carbide drill is specifically designed for machining various types of stainless steel, including austenitic, super-austenitic, ferritic, and duplex stainless steels. The drill is manufactured from high-quality micro-grain tungsten carbide, which offers high hardness, wear resistance, and the ability to withstand high temperatures without losing its cutting performance. Additionally, the drill features a DP (Diamond Performance) high-performance coating to enhance corrosion resistance and durability, ensuring superior performance during extended use.
2. Internal Cooling System
Equipped with an advanced internal cooling system, the SDF-M series delivers coolant directly to the cutting zone via internal channels. This design effectively reduces cutting temperatures, minimizes thermal deformation, extends tool life, and ensures excellent surface finish and machining accuracy. The internal cooling system also significantly improves chip evacuation efficiency, reducing issues such as chip clogging or overheating, thereby enhancing overall machining quality and reliability.
3. Optimized Flute Design
The flute geometry of the drill is meticulously engineered to optimize chip evacuation. The unique flute design facilitates smooth chip removal, prevents chip buildup, and avoids overheating and tool wear. This design not only increases drilling speed and quality but also enhances the stability and reliability of the machining process, especially suitable for prolonged continuous operations.
4. DP High-Performance Coating
The DP coating is specifically designed for high-load and challenging machining tasks. It provides exceptional resistance to high temperatures and wear, significantly reduces friction and wear rates, and dramatically increases the service life and machining efficiency of the drill. The DP coating maintains stable cutting temperatures during high-speed operations, ensuring efficient processing performance.
5. Centering Ability and Precision
The SDF-M series drills exhibit outstanding centering capability with tolerances reaching IT8-9, ensuring precise hole positioning and meeting high-precision machining requirements. This high-precision centering ability helps reduce deflection and vibration, guaranteeing straightness and roundness in drilled holes, thus enhancing overall machining quality. Accurate drilling is crucial for subsequent processes like threading or assembly.
6. Deep Hole Drilling Capability
Capable of achieving drilling depths up to 8 times the diameter, the SDF-M series is ideal for deep-hole drilling applications. This feature makes the drill suitable for scenarios requiring long drill holes, such as in aerospace, automotive manufacturing, and other precision engineering fields. The deep-hole drilling capability broadens the application range and provides reliable solutions for varying drilling depth requirements.
