Dormer Pramet R454 9.80 mm CARBIDE TIALN FORCE-X STEPPED SHANK STANDARD SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R454 9.80 mm carbide drill is designed for precision and durability in metalworking. With a 9.80 mm diameter and premium carbide, this drill delivers clean, accurate holes across steel, aluminium, and stainless steel. The FORCE-X stepped shank and DIN 6537 L compatibility ensure secure grip and reliable performance in standard tool holders.

Its 140-degree, 4-facet split point helps self-centering at start-up and reduces the push force required to begin cutting, while the CTW flute design adds rigidity for higher cutting speeds and feeds. The Titanium Aluminium Nitride coating further extends tool life, enabling consistently tight tolerances (h9) and high-quality holes even at higher speeds.

• Self-centering 140° four-facet split point: Starts true on contact, reduces wander, and lowers the effort needed to initiate the cut for more reliable hole accuracy.
• TiAlN-coated premium carbide: Delivers extended tool life and better performance when drilling harder materials, reducing downtime and tool changes.
• CTW flute design with stepped shank: Increases strength and allows higher speeds and feeds, while the stepped shank ensures secure engagement in standard holders for consistent results.

This drill is built to streamline production: fewer startup wander, longer intervals between tool changes, and faster cycle times thanks to high-speed capability and reliable hole quality. The R454 combines robust materials and thoughtful geometry to deliver repeatable results across common metals, helping you finish projects on time and with confidence.
