Dormer Pramet R454 8.50 mm CARBIDE TIALN FORCE-X STEPPED SHANK STANDARD SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R454 8.50 mm carbide drill is built for reliable, precise hole making across a wide range of materials. With a stepped shank and a DIN 6537 L size, it fits common chucks and setups, making it a versatile choice for shops, fabrication, and hobbyist projects.

Its performance comes from a smart combination of point geometry, coating, and flute design: a 140° four-facet split point promotes self-centering and reduces starting push force; a Titanium Aluminium Nitride (TiAlN) coating extends tool life and improves drilling on harder materials; and a CTW flute design adds strength to support higher cutting speeds and feeds.

• 140° four-facet split point: Self-centering start with reduced push force, helping you achieve clean, accurate holes from the first cut.
• TiAlN coating: Extends drill life and maintains sharpness, delivering better performance when drilling hard materials and reducing heat-related wear.
• Special CTW flute design: Increased strength that supports higher cutting speeds and feeds, delivering stable, reliable hole quality at speed.

These features translate into real-world advantages: consistent hole quality at high speeds and feeds, fewer reworks, longer tool life, and the ability to drill a wide range of materials—from steel to aluminum and stainless steel. The precision geometry helps you hit tight tolerances, including h9 hole tolerance, with confidence. For professionals and DIYers alike, this drill delivers reliable results and faster, more predictable workflows.
