Dormer Pramet R459 6.60 mm CARBIDE TIALN FORCE-X STEPPED SHANK LONG SERIES (X8D) DRILL

The Dormer Pramet R459 6.60 mm carbide drill is a high‑performance tool designed for a wide range of materials, from steel and stainless steel to aluminium. Its premium carbide core is coated with Titanium Aluminium Nitride (TiAlN) to extend life and maintain sharpness under demanding cutting conditions. The 140° four‑facet split point provides self‑centering start and reduces the push force needed, helping you achieve clean, accurate holes with less wandering—perfect for production runs and precise work alike.

The drill features a long stepped shank for deeper holes and enhanced rigidity, making it ideal for applications that demand reach without compromising accuracy. Its CTW flute design, combined with a coolant feed, delivers greater strength and enables higher cutting speeds and feeds while efficiently evacuating chips. This combination supports faster cycle times and reliable performance across a variety of materials.

• 140° 4‑Facet Split Point: Ensures quick, accurate starts with less drift or walking, reducing rework and improving first‑hole quality.
• Titanium Aluminium Nitride (TiAlN) Coating: Shields the carbide edge from heat and wear, extending drill life and maintaining performance on tougher materials.
• CTW Flute Design with Coolant Feed: Combines strength with efficient chip evacuation and supports higher speeds and feeds for consistent, high‑quality holes.

Designed for dependable, production‑grade results, this drill pairs precise geometry with durable construction to deliver repeatable hole quality (H9 tolerance) and reduced downtime. Its versatility across common engineering materials makes it a trusted choice for workshops, job sites, and fabrication floors seeking reliable performance without frequent tool changes.
