Dormer Pramet R457 7/32 Inch CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 7/32 Inch carbide drill is a compact, high-precision tool designed for a wide range of materials. With a stepped shank and the short-series (X3D) design, it clamps securely for fast setup and repeatable results in both production runs and workshop work. The 140° four-facet split point helps the bit start true and self-center, reducing wandering and push force for cleaner entry.

Coated with TiAlN for longer life, it performs better when drilling harder materials. The CTW flute design with coolant feed delivers increased strength and lets you run at higher cutting speeds and feeds, while efficient coolant and chip evacuation help maintain tool temperatures and hole accuracy. This premium carbide drill is suitable for drilling steel, aluminum, stainless steel, and more, capable of producing high-quality holes within h9 tolerance and dependable results across many applications.
