Dormer Pramet R458 6.70 mm CARBIDE TIALN FORCE-X STEPPED SHANK SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R458 6.70 mm carbide drill is a versatile, high-precision tool designed for reliable hole making across a range of metals. Built to DIN 6537 K specifications, it features a compact short-series (X3D) design with a stepped shank for rigid engagement in standard drill chucks. Ideal for engineers, builders, and hobbyists alike, this drill delivers consistent performance in everyday metalworking tasks.

Key to its performance is the 140-degree four-facet split point, which helps the drill self-center and reduces the startup push force. Add in the Titanium Aluminum Nitride (TiAlN) coating for extended tool life and improved performance on harder materials, and you have a drill that stays sharp longer under demanding cuts. The CTW flute design provides added strength and enables higher cutting speeds and feeds, helping you complete jobs faster with fewer interruptions.

• 140° 4‑Facet Split Point: Self-centering starting action and reduced push force mean quicker, more accurate holes with less effort at the start of each drill.
• TiAlN Coating for Longer Life: Increases tool life and enhances performance when drilling harder materials, reducing replacement downtime.
• CTW Flute Design: Increased strength and the ability to run at higher speeds and feeds for faster, more reliable drilling.

This high‑performance carbide drill is capable of producing high-quality, accurate holes with tight control (H9 tolerance) across steel, aluminium, and stainless steel. The combination of a durable carbide core, coating, and optimized flute geometry ensures dependable results, reduced wear, and fewer tool changes—helping you improve workflow, save time, and achieve consistent results in both professional shops and DIY projects.
