Where HDCS636 fits in the process sequence

The HDCS636 series TiN-coated left-hand step solid carbide drill delivers precise stepped hole machining with consistent performance across a wide diameter range.

Series Overview and Application

The HDCS636 series is specifically designed for non-standard step drilling applications, where stepped and counterbored holes are required. This series is ideal for machining operations that demand high precision and surface finish, especially in materials that are difficult to drill. The TiN coating enhances tool life and reduces friction, making it suitable for a variety of industrial applications. The series includes multiple part numbers, each tailored to specific drilling requirements, ensuring that the right tool is available for every job.

Measured Values and Their Impact on Machining

Two key measured values from the HDCS636 series are critical in determining its effectiveness in machining processes. The first is the diameter range, which spans from 0.433 mm to 3.0 mm. This wide range allows the series to be used in a variety of applications, from fine detailed work to larger hole drilling. The second measured value is the minimum diameter capability of 0.15 mm, which is essential for applications requiring very small, precise holes. These measurements ensure that the HDCS636 series can handle both small and large diameters with consistent quality.

The diameter range and minimum diameter capability directly influence the machining process by determining the versatility and precision of the tool. A wider diameter range allows for greater flexibility in tool selection, while the minimum diameter capability ensures that the tool can handle the smallest and most intricate drilling tasks. These features are crucial for maintaining the integrity of the workpiece and achieving the desired surface finish.

Performance and Reliability

The HDCS636 series is built to provide reliable performance in demanding machining environments. The TiN coating not only improves tool life but also reduces heat generation during the drilling process, which is essential for maintaining tool integrity and workpiece quality. The series is designed to work efficiently with various materials, making it a versatile choice for manufacturers and machinists. The combination of precise geometry and durable coating ensures that the HDCS636 series meets the high standards required in modern manufacturing.
