Dormer Pramet R459 21/64 Inch CARBIDE TIALN FORCE-X STEPPED SHANK LONG SERIES (X8D) DRILL

The Dormer Pramet R459 21/64 Inch Carbide TiAlN Force-X Stepped Shank Long Series drill is a high-performance tool built for professionals and serious hobbyists who demand consistent, precise holes across a range of metals. Its stepped shank and long-series design provide secure engagement and deep-hole capability, while the 140° 4-facet split point helps the drill start accurately with minimal wandering.

With a Titanium Aluminium Nitride (TiAlN) coating and a premium carbide body, this drill is engineered for durability and versatile material compatibility—including steel, aluminum, and stainless. The combination of Force-X geometry, a special flute design, and integrated coolant capability enables higher cutting speeds and feeds while maintaining control and hole quality, delivering reliable results with reduced downtime and excellent hole tolerance.

• Self-centering 140° four-facet split point: Starts holes quickly with minimized wandering and lower push force, delivering clean entry every time.
• TiAlN-coated premium carbide: Extends tool life and enhances performance on harder materials, reducing tool changes and maximizing productivity.
• CTW flute design with coolant feed: Adds strength and supports higher speeds and feeds, while efficient chip evacuation keeps cutting temperatures down for smoother operation.

By combining precision, durability, and versatility, the drill helps you complete projects faster with fewer interruptions. The self-centering point reduces rework, the TiAlN coating withstands wear in demanding materials, and the CTW flute with coolant feed maintains robust performance at higher speeds. The long-series stepped shank ensures reliable engagement across a variety of machines, while delivering consistent, H9-toleranced holes that meet professional fabrication standards.
