Dormer Pramet R454 8.40 mm CARBIDE TIALN FORCE-X STEPPED SHANK STANDARD SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R454 8.40 mm carbide drill is the right choice for professionals and serious DIYers who demand reliable, precise holes with minimal setup. Built as a DIN 6537 L standard tool, it combines a tough carbide core with a Titanium Aluminium Nitride (TiAlN) coating and a FORCE-X stepped shank to deliver consistent performance across steel, aluminium, and stainless steel.

• Self-centering 140° four-facet split point: starts cleanly and centers itself, reducing push force and minimizing wandering for faster, more accurate hole initiation.
• TiAlN coating for longer tool life: enhances wear resistance and heat tolerance, extending service life when drilling harder materials and delivering steady performance over more holes.
• CTW flute design with Force-X stepped shank for rigidity: provides greater strength at high speeds and feeds, improves hole quality, and keeps the drill securely aligned in standard toolholders.

This drill is designed to help you achieve high-quality, repeatable results with less downtime. Its combination of a premium carbide core, protective TiAlN coating, and engineered flute and shank geometry supports fast cycle times, tighter hole tolerances (H9 range), and reliable performance across a range of common materials. Whether you’re fabricating parts in a shop or tackling a demanding project at home, this drill delivers consistent results and confidence to get the job done right.
