The SDF-R series professional high-performance internal cooling solid carbide drill with DP coating is designed for specialized machinery, molds, automotive, and energy industries. This tool meets the demands for high precision and efficient machining in these sectors. The drill is particularly suitable for ISO workpiece material groups P (steels) and M (stainless steels and heat-resistant alloys), ensuring excellent cutting performance and extended tool life across different materials.

This drill achieves hole diameter tolerances of IT8 to IT9, guaranteeing high dimensional accuracy, which is ideal for the manufacture of precision parts. Available in diameters ranging from D3mm to D20mm, it supports a variety of machining tasks, with a maximum drilling depth reaching up to 8 times the drill diameter, suitable for deep-hole applications.

Material Characteristics

The SDF-R series drills are manufactured using high-quality solid tungsten carbide as the base material. Tungsten carbide is renowned for its exceptional hardness, superior wear resistance, and compressive strength. Compared to high-speed steel, tungsten carbide exhibits higher heat resistance, maintaining its geometric shape and cutting performance even at elevated temperatures, making it ideal for machining high-hardness materials. Additionally, tungsten carbide offers excellent chemical stability, reducing tool wear by minimizing reactions with the workpiece material.

Design-Merkmale

• Internal Cooling System: Designed with internal coolant channels that ensure coolant reaches the cutting zone directly, effectively lowering cutting temperatures, improving chip evacuation, and minimizing tool damage caused by overheating.
• Optimized Geometric Structure: The drill point angle is meticulously engineered for optimal entry; the helix angle is selected to balance efficient chip removal and the distribution of cutting forces, reducing vibration risks and ensuring straight and smooth drilling.
• Land Treatment: Precise control over land width and position further improves drill stability, especially during deep hole drilling.
• Diameter and Depth Range: Available in a variety of sizes from D3mm to D20mm, suitable for different hole diameters; capable of drilling depths up to 8 times the drill diameter, supporting efficient deep-hole processing.

Beschichtungstechnologie

• DP Coating: This is a specialized coating technology developed to enhance drill performance. The DP coating not only provides outstanding lubrication, reducing friction coefficients, but also enhances the drill’s oxidation resistance and wear resistance. Under high-temperature conditions, the coating remains stable, extending tool life and improving surface finish quality.

Application Areas

• Wide Applicability: The SDF-R series drills are particularly suited for machining various types of steels and stainless steel materials, commonly found in specialized machinery, mold manufacturing, automotive part production, and energy equipment manufacturing.
• Precision Requirements: They meet IT8 to IT9 class hole diameter tolerance requirements, ensuring holes have high dimensional accuracy and roundness, suitable for precision mechanical parts manufacturing.
• Production Efficiency: Due to their excellent cutting performance and long service life, SDF-R series drills can significantly increase machining speeds, reduce tool change frequency, and thus enhance overall production efficiency.

Summary

The SDF-R series professional high-performance internal cooling solid carbide drill with DP coating integrates advanced material science, innovative design, and efficient coating technology into a high-end tool. Tailored to address the challenges of high-precision machining under complex working conditions, it performs exceptionally well under continuous heavy-duty operations and complex working conditions, making it an ideal choice for those pursuing high-quality and efficient machining.
