Dormer Pramet R458 11.70 mm CARBIDE TIALN FORCE-X STEPPED SHANK SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R458 11.70 mm carbide drill is a high-performance tool built for professionals and serious hobbyists who need precise, repeatable holes in metal. With a 11.70 mm diameter and a DIN 6537 K shank, it fits standard chucks and toolholders, and the short FORCE-X stepped shank supports quick changes and secure seating in busy shops.

From center starts to finished holes, the 140° four-facet split point self-centers and reduces starting thrust for clean, accurate begins. The TiAlN coating extends tool life and improves wear resistance when drilling harder materials, while the CTW flute design adds strength to enable higher speeds and feeds for productive drilling. Crafted from premium carbide, this drill is built for reliable performance across a range of metals, delivering consistent results at higher productivity.

• 140° four-facet split point: Self-centering entry reduces wandering and lowers the push force, helping you start holes accurately on the first cut.
• TiAlN coating (Titanium Aluminium Nitride): Significantly extends drill life and maintains sharpness when drilling steel, aluminum, stainless steel, and other hard materials.
• CTW flute design for strength and high-speed cutting: Increases rigidity and enables higher cutting speeds and feeds, delivering faster holes with better surface finish.

This drill delivers reliable performance across steel, stainless steel, and aluminum, helping you finish projects faster with fewer reworks. The combination of a precise split point, wear-resistant TiAlN coating, and a robust CTW flute design translates to cleaner holes with tight tolerances (including h9), reduced downtime, and long service life. The DIN 6537 K shank and compact short form ensure a secure fit in standard toolholders, making it a dependable choice for production runs, workshops, and DIY projects alike.
