Dormer Pramet R454 N4 CARBIDE TIALN FORCE-X STEPPED SHANK STANDARD SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R454 N4 carbide drill is a high-performance tool designed for engineers, machinists, and DIY enthusiasts who need precise and repeatable holes across common metals. Its 140-degree four-facet split point helps the bit start exactly on center, reducing wander and the pushing effort required to begin cutting. With a high-quality H9 hole tolerance, you can trust it to deliver clean, accurate holes right from the first pass.

• Precision start: 140° 4‑facet split point: Self-centering entry minimizes wandering and lowers the force needed to begin cutting, enabling clean starts and consistent hole location across materials.
• TiAlN coating for extended life: The Titanium Aluminium Nitride coating boosts wear resistance, extending tool life and maintaining sharpness when drilling harder or abrasive materials, even at higher speeds.
• CTW flute design with stepped DIN 6537 L shank: The CTW flute design increases strength for higher cutting speeds and feeds, while the stepped shank provides secure chuck engagement and reliable performance on steel, aluminium, and stainless steel.

This drill pairs premium carbide with a robust design to deliver reliable, high-quality holes quickly and consistently. The combination of a precision start, durable coating, and optimized flute and shank geometry helps reduce downtime, improve throughput, and provide dependable results across a wide range of common metals.
