Dormer Pramet R454 4.20 mm CARBIDE TIALN FORCE-X STEPPED SHANK STANDARD SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R454 4.20 mm carbide drill is a high-performance cutting tool designed for precise, reliable hole drilling across a range of metals. With a 4.20 mm diameter and a DIN 6537 L shank in the Standard Series (X5D), it’s ready for demanding tasks in workshops, fabrication shops, and DIY projects where consistent hole quality matters.

A combination of a 140° four-facet split point, a TiAlN coating, and a CTW flute design delivers self-centering starts, longer tool life, and the ability to run at higher speeds and feeds. Crafted from premium carbide, it handles steel, aluminium, and stainless steel with reliable, repeatable results, maintaining tight hole tolerances (h9) even under demanding conditions.

• Self-centering 140° four-facet split point: Starts holes cleanly and reduces push force, helping you minimize wandering and maintain accuracy.
• TiAlN coating for longer tool life: Increases wear resistance and performance on harder materials, extending service life and reducing tool changes.
• CTW flute design for strength and speed: Adds rigidity and enables higher cutting speeds and feeds for faster, more consistent hole production.

The tool is built for reliability in real-world use: it’s capable of producing high-quality, accurate holes at high speeds and feeds, with h9 hole tolerance across steel, aluminium, and stainless steel. This makes it a dependable choice for production runs, fabrication tasks, and precision work where uptime, repeatability, and finish matter.
