Dormer Pramet R459 8.50 mm CARBIDE TIALN FORCE-X STEPPED SHANK LONG SERIES (X8D) DRILL

The Dormer Pramet R459 8.50 mm carbide drill is a high-performance tool built for professionals and serious hobbyists who need reliable, precise holes across a range of materials. Its long-series stepped-shank design delivers extended reach for deep drilling, making it ideal for through-holes and challenging workpieces where access is limited.

Engineered for speed and durability, this drill combines a premium carbide core with a Titanium Aluminium Nitride (TiAlN) coating, a 140° four-facet split point for easy starts, and a CTW flute design with coolant feed. Together, these features enable higher cutting speeds and feeds, improve hole quality, and extend tool life when drilling steel, aluminum, and stainless steel.

• Self-centering 140° 4-facet split point: Starts holes cleanly with reduced wander and lower push force, improving first-pass accuracy and reducing tool walk on tough materials.
• TiAlN coating for longer life: The TiAlN coating enhances wear resistance, maintaining sharpness at higher speeds and across harder materials to lower tool changes and downtime.
• CTW flute design with coolant feed: Designed for strength and efficiency, this flute geometry supports higher speeds and feeds while delivering effective cooling and chip evacuation for deeper holes.

This drill is capable of producing high-quality, accurate holes with tight tolerances (h9) across a variety of materials, helping to improve workflow, reduce rework, and deliver consistent results in demanding applications.
