Dormer Pramet R454 4.50 mm CARBIDE TIALN FORCE-X STEPPED SHANK STANDARD SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R454 4.50 mm carbide drill combines a DIN 6537 L shank with a FORCE-X stepped shank design for secure seating in standard chucks and collets. Its 140-degree four-facet split point starts true and minimizes push force, helping you drill precise holes straight from the first touch.

Coated with Titanium Aluminium Nitride (TiAlN) for extended life and improved performance on harder materials, and built with a CTW flute design for greater rigidity at high speeds and feeds, this premium carbide drill delivers consistent, high-quality holes—even at production speeds. It is suitable for drilling steel, aluminium, and stainless steel with hole tolerance tightness around h9.

• Self-centering 140° four-facet split point: Starts cleanly, reduces wandering, and lowers push force for easier and more accurate hole initiation.
• TiAlN coating for longer tool life: Extends service life and maintains performance when drilling harder materials, reducing tool changes and downtime.
• CTW flute design for higher speeds and feeds: Increases rigidity and allows faster cutting with cleaner finishes and improved overall productivity.

This drill helps you produce precise, repeatable holes quickly and reliably, delivers durable performance across common materials, and supports efficient workflows from manual setups to automated processes. With its robust carbide core, coated longevity, and optimized flute geometry, you can trust it to maintain hole quality and finish while reducing rework and downtime in everyday manufacturing and fabrication tasks.
