SDF-R Series Professional High-Performance External Cooling Solid Carbide Drill with DP Coating

Material Characteristics

The integral tungsten carbide construction provides the drill with exceptional hardness and strength, enabling it to perform stably under high loads for extended periods. It also offers good chemical stability, reducing the likelihood of reactions with the workpiece material. Tungsten carbide is known for its superior heat resistance and wear resistance, making it an ideal choice for high-performance machining.

Geometric Design

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. Precise control over land width and position further improves drill stability, especially during deep hole drilling.

Tecnología de revestimiento

The DP coating enhances the drill’s wear resistance and oxidation resistance, maintaining stable performance even under high-temperature conditions, extending tool life, and providing superior surface finish quality. The DP coating not only increases durability but also significantly reduces friction, optimizing energy consumption during the cutting process.

Cooling System

The external cooling system design ensures that coolant can be delivered close to the cutting zone, effectively lowering cutting temperatures, improving chip evacuation, minimizing tool wear, and enhancing machining efficiency and surface quality. Good cooling effects are crucial for maintaining the sharpness of the cutting edge and extending tool life.

Materiales adecuados

This drill is 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 makes it highly effective in a wide range of applications, from ordinary steels to difficult-to-machine stainless steels and high-temperature alloys.

Hole Diameter Tolerances

The drill achieves hole diameter tolerances of IT8 to IT9, guaranteeing high dimensional accuracy, which is ideal for the manufacture of precision parts. Such levels of tolerance are critical for mechanical components requiring tight fits, reducing the need for secondary operations and improving assembly efficiency.

Size Range

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.

Application Areas

The SDF-R series professional high-performance external cooling solid carbide drill with DP coating is designed for specialized machinery, molds, automotive, and energy industries, meeting the demands for high precision and efficient machining in these sectors. The tool is particularly suited for applications requiring long-term stable performance and high-precision processing.
