Dormer Pramet R458 21/32 Inch CARBIDE TIALN FORCE-X STEPPED SHANK SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R458 21/32 Inch Carbide TiAlN Force-X Short Series Drill (DIN 6537 K) is a high-performance carbide drill designed for fast, precise metal holemaking. With a 21/32 in diameter and a short, Force-X design with a stepped shank, it fits securely in standard toolholders and minimizes runout. Its 140-degree, four-facet split point self-centers for clean starts and reduces the push force required to begin cutting.

Coated with Titanium Aluminium Nitride (TiAlN), this drill delivers longer tool life and improved wear resistance, especially in demanding materials. The ctw flute design enhances strength and supports higher cutting speeds and feeds, while the premium carbide construction ensures reliable drilling across a range of metals including steel, aluminium, and stainless steel. The drill maintains high-quality hole accuracy with an H9 hole tolerance even at elevated speeds.

• Self-centering 140° four‑facet split point: starts holes cleanly and reduces thrust, helping you achieve true, straight holes from the first cut.
• TiAlN coating for longer life: increases wear resistance and performance in tough materials, reducing tool changes and downtime.
• CTW flute design with stepped shank: adds strength to sustain higher speeds and feeds while ensuring secure mounting in standard holders for consistent results.

This drill is a reliable, professional choice for engineers, machinists, and hobbyists alike. It delivers precise, repeatable holes across common metals, enhances productivity with faster cutting conditions, and provides confidence in performance and longevity when tackling demanding drilling tasks.
