Dormer Pramet R457 N5 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

Introducing the Dormer Pramet R457 N5 carbide drill, a TiAlN-coated Force-X tool designed for a compact, short-series (X3D) profile with a stepped shank and coolant feed. Built to DIN 6537 K standards, this drill is ideal for engineers, fabricators, tradespeople, and serious hobbyists who demand reliable, precise holes across a range of metals.

This drill features a 140-degree four-facet split point for self-centering entry, reducing wand­er and the push force required to start cutting. The premium carbide core delivers strong, consistent performance, while the TiAlN coating extends tool life and maintains cutting performance on harder materials. A CTW flute design with integrated coolant feed enhances strength, keeps chips under control, and enables higher cutting speeds and feeds for productive hole-making.

• Self-centering 140° four‑facet split point: Starting holes cleanly with less wander and reduced effort, improving first-pass accuracy.
• TiAlN-coated premium carbide: Longer tool life and reliable performance on steel, aluminum, and stainless steel for fewer tool changes.
• CTW flute design with coolant feed: Enhanced rigidity and chip evacuation that support higher speeds and feeds without compromising hole quality.

In practical use, the R457 N5 delivers high-quality, accurate holes (h9 tolerance) even at elevated speeds and feeds, making it a dependable choice for mixed-material workstreams. The stepped shank and short-series design provide stable, repeatable results in compatible holders, helping you reduce downtime and keep production moving smoothly.
