Dormer Pramet R458 19.50 mm CARBIDE TIALN FORCE-X STEPPED SHANK SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R458 is a 19.50 mm carbide drill designed for DIN 6537 K tool holders. Its 140-degree four-facet split point helps you start holes with precision, self-centering the tip and reducing the push force needed for cleaner, easier drilling. The Titanium Aluminium Nitride (TiAlN) coating enhances tool life and performance when drilling harder materials.

Built for rigidity and speed, this drill features a CTW flute design and a short stepped shank (X3D) that provide increased strength and allow higher cutting speeds and feeds. With premium carbide capable of drilling steel, aluminium, and stainless steel, it delivers high-quality, accurate holes with tight tolerances (h9) even at demanding speeds.

• Self-centering 140° four-facet point: Helps with precise start and reduces the push force required, resulting in cleaner holes and less wandering.
• TiAlN coating for extended life: Increases tool life and improves performance when drilling harder materials, reducing downtime and rework.
• CTW flute design with stepped X3D shank: Provides greater strength for higher speeds and feeds, supports reliable cutting across multiple materials, and helps achieve consistent hole quality with h9 tolerances.

This combination of geometry, coating, and carbide quality translates to reliable, repeatable results that help you complete jobs faster, minimize tool changes, and achieve precise, professional holes across a variety of metalwork applications.
