DIN 1897

Solid carbide twist drills per DIN 1897 – High-Performance drills from Nachreiner

Twist drills per DIN 1897, also known as countersinks or machine stub drills, are specialized metal drills primarily used in machines designed for automated drilling in large-scale production. In the automotive industry, for instance, many robots engaged in drilling holes in vehicle panels are typically equipped with twist drills per DIN 1897. Due to their short design, DIN 1897 metal drills are not suitable for deep holes; to drill through-holes, the material should not be too thick. The shorter length of DIN 1897 twist drills enhances stability and robustness and improves precision, which is essential for reliable automated drilling. As a result, solid carbide (VHM) machine stub drills are especially well-suited to these applications.

Specifications for DIN 1897 twist drills

Exact dimensions, required material properties, and tolerance values for these drills are typically set in industry standards like DIN 1897. However, metal drills that meet this standard can still vary significantly in quality, with low-cost options often lacking in performance. Therefore, DIN compliance alone does not guarantee the quality of a drill. For customers needing twist drills per DIN 1897, we recommend Nachreiner’s high-quality machine stub drills, which offer the reliability, precision, and durability required for professional use. Although HSS (high-speed steel) and HSSE (with cobalt alloying) versions are also excellent in their applications, we also offer solid carbide (VHM) variants. VHM drills are ideal for machining particularly tough metals and similarly resilient materials. While many HSS and HSSE drills have carbide tips, VHM drills are made entirely from solid carbide. This construction offers superior durability, longer tool life, higher stability under lateral forces, and significantly faster cutting speeds compared to other versions. In areas of metalworking where high production speeds are critical, solid carbide tools excel in large-scale production.

Enhanced variants and custom solutions from Nachreiner

Sometimes even solid carbide alone may not be sufficient. If you have requirements beyond the specifications of DIN 1897, need special sizes, or want a unique coating for your twist drills, we can typically fulfill these requests. Contact our experts, who can provide personalized advice and an offer tailored to your needs. If your existing cutting tools and metal drills require regrinding, we offer this service as well. This saves costs and extends the lifespan of your high-quality Nachreiner twist drills. Naturally, this service is also available for products from other manufacturers, as customer satisfaction is our priority.
