Dormer Pramet R458 21/64 Inch CARBIDE TIALN FORCE-X STEPPED SHANK SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R458 21/64 Inch Carbide TiAlN FORCE-X Stepped Shank Short Series drill is a high-performance carbide drill designed for reliable holemaking across a range of materials. Built for engineers, machinists, tradespeople and hobbyists, it features a FORCE-X stepped shank for rigidity and easy mounting on standard DIN 6537 K tooling, ensuring consistent starts and minimal setup fuss.

Its 140-degree 4-facet split point provides self-centering starting action and reduces push force, while a Titanium Aluminium Nitride (TiAlN) coating extends wear life and improves performance when drilling harder metals. The CTW flute design adds strength and enables higher cutting speeds and feeds, delivering fast, clean holes without sacrificing accuracy.

• 140° 4-Facet Split Point: Self-centering start and reduced piloting effort for accurate hole beginnings.
• TiAlN Coating: Hard-wearing surface that extends tool life and boosts performance on hard-to-machine materials.
• CTW Flute Design: Stronger flutes that support higher speeds and feeds for faster material removal and consistent results.

With this drill, you gain reliable, high-quality holes across steel, aluminum, and stainless steel, even at higher speeds and feeds. The durable carbide core and TiAlN coating minimize wear, reducing tool changes and downtime, while the DIN 6537 K-compatible shank and FORCE-X geometry deliver predictable performance every shift. Designed to meet tight tolerances (h9), it helps improve workflow, accuracy, and overall productivity on demanding projects.
