Dormer Pramet R457 5.80 mm CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 is a 5.80 mm carbide drill designed for reliable, precise holemaking with a DIN 6537 K shank and a compact short-series (X3D) geometry. It’s built to perform across a broad range of materials, from steel to aluminium, with tools you can depend on in production runs, workshops, or hobbyist projects.

• 140° four-facet split point: Enables easy self-centering at startup and reduces push force, delivering smoother hole entry and more consistent starts.
• TiAlN coating for longer life: Extends tool life and maintains performance when drilling harder materials, helping you work longer between tool changes.
• Special flute design with coolant feed: Provides increased strength and allows higher cutting speeds and feeds, while improving chip evacuation for cleaner holes and cooler operation.

This high-performance drill is built to deliver high-quality, accurate holes at elevated speeds and feeds (h9 tolerance). The premium carbide construction handles a wide material range—steel, aluminium, and stainless steel—with reliable results. The stepped, coolant-fed design and compact X3D form factor ensure compatibility with standard equipment and tighter workspaces, making it a dependable choice for productive drilling across diverse applications.
