Dormer Pramet R457 N8 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 N8 carbide drill is a high‑performance tool designed for engineers, buyers, tradespeople, and hobbyists who need reliable, precise holes fast. Built with a Force‑X stepped shank and coolant feed in a compact short‑series design (X3D), it delivers versatile performance in busy shops and on portable machines. It is compatible with DIN 6537 K sizing for straightforward tool selection.

Equipped with a 140‑degree, four‑facet split point and a Titanium Aluminium Nitride (TiAlN) coating, this drill centers itself, reduces starting push force, and boosts tool life even when drilling tougher materials. The CTW flute design with coolant feed increases strength and allows higher cutting speeds and feeds, while the premium carbide construction handles steel, aluminium, and stainless steel with consistent, high‑quality results and tight tolerances (h9).

• 140° four‑facet split point: Self‑centering start and reduced thrust, promoting clean hole starts and minimizing wandering in less-than-perfect setups.
• TiAlN coating: Extends tool life and maintains sharpness when drilling harder materials, reducing tool changes and downtime.
• CTW flute design with coolant feed: Enhances strength and enables higher speeds and feeds, with efficient cooling and chip evacuation for smoother drilling.

With the R457 N8, you gain dependable, high‑quality holes at speed across a variety of materials, backed by longer tool life and improved process stability. The drill’s design supports precise hole tolerances (h9) and consistent results, helping you finish jobs faster with fewer reworks.
