Dormer Pramet R453 N21 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED STANDARD SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R453 N21 carbide drill is a premium, coolant-fed tool designed for professional workshops, job shops, and maintenance teams. Built from high‑quality carbide and finished with TiAlN coating, it delivers reliable performance across steel, aluminum, and stainless steel while supporting standard setups with its stepped shank and DIN 6537 L compatibility. This drill is engineered to produce clean, repeatable holes with less effort during setup and operation.

The 140° four-facet split point provides self-centering action and reduces the push force required to start drilling, helping you locate holes quickly and accurately. A CTW flute design combined with coolant feed adds strength and enables higher cutting speeds and feeds, improving productivity without sacrificing hole quality. The premium carbide core and TiAlN coating work together to extend tool life in demanding materials and tough drilling tasks.

• 140° four-facet split point: Self-centering geometry that minimizes wandering at start-up, reducing push force and delivering fast, precise hole initiation.
• TiAlN coating on carbide: Enhances wear resistance and tool life, delivering consistent performance across steel, aluminium, and stainless steel—even at higher speeds.
• CTW flute design with coolant feed: Reinforced flute geometry and coolant delivery for stronger cutting action, better chip evacuation, and the ability to run at higher speeds and feeds.

This drill helps streamline your workflow by delivering high‑quality, tight-tolerance holes (H9) with reliable performance at speed, reducing rework and downtime. Its blend of advanced coating, sturdy carbide, and coolant-assisted design supports versatile use in mixed-material projects, making it a dependable choice for engineers, machinists, and technicians who demand consistent results and efficient production.
