Dormer Pramet R459 3.70 mm CARBIDE TIALN FORCE-X STEPPED SHANK LONG SERIES (X8D) DRILL

The Dormer Pramet R459 3.70 mm carbide drill is a long-series, stepped-shank tool designed for precise, efficient hole-making across steel, aluminum, and stainless steel. With a 3.70 mm diameter and X8D stepped shank, it seats securely in standard chucks while the 140° four-facet split point starts cleanly and minimizes wandering. This combination helps you achieve consistent starts and accurate holes right from the first cut.

The R459 is built for durability and repeatable results. The Titanium Aluminium Nitride (TiAlN) coating extends tool life and improves performance when drilling harder materials, reducing wear and downtime. The CTW flute design with coolant feed provides increased strength, enabling higher cutting speeds and feeds, while delivering effective chip evacuation for clean holes and reduced heat buildup. When used at appropriate speeds, it can produce high-quality, accurate holes with h9 tolerance.

• Self-Centering 140° Four-Facet Split Point: Starts true with minimal wander, reducing push force and helping you locate the hole center quickly for precise first-pass hole accuracy.
• TiAlN Coating for Longer Life: Coating resists wear and heat, extending tool life and maintaining sharpness when drilling harder materials like stainless steel and alloys.
• CTW Flute Design with Coolant Feed and Stepped Shank (X8D): Combines strong, rigid flute geometry with coolant-assisted cutting and a secure stepped shank for higher speeds, improved feeds, and reliable chip evacuation.

Designed for professionals who demand consistency and speed, this drill delivers precise, clean holes with minimal downtime. Its durable carbide core, TiAlN coating, and optimized geometry work together to boost productivity, reduce tool changes, and ensure reliable performance across a range of common materials.
