Dormer Pramet R457 20.00 mm CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 20.00 mm carbide drill is a premium holemaking tool designed for engineers, machinists, tradespeople, hobbyists, and DIY enthusiasts who demand reliable, high-quality results. With a 20 mm diameter and a DIN 6537 K shank in a compact short-series form, it fits standard drill chucks and holders for quick, consistent setups in any workshop.

Key design features include a 140° four-facet split point that self-centers and reduces push force, a Titanium Aluminum Nitride (TiAlN) coating to extend life and performance on harder materials, and a CTW flute design with coolant feed that supports higher speeds and feeds while preserving hole quality. The FORCE-X stepped shank enhances grip and stability in tight spaces, making this drill a versatile choice for a wide range of materials.

• 140° 4-Facet Split Point for Self-Centering: Starts holes cleanly with less wandering and lower thrust, improving first-hole accuracy and reducing operator effort.
• TiAlN Coating + Premium Carbide for Extended Life: Delivers superior wear resistance and longevity across steel, aluminium, and stainless steel, reducing tool changes and downtime.
• CTW Flute Design with Coolant Feed for Higher Speeds: Optimized flute geometry and coolant delivery enable faster drilling with strong chip evacuation and consistent hole quality.

Designed for precise, repeatable results, this drill helps you finish projects faster with fewer reworks. Its H9 hole tolerance capability, combined with durable carbide and advanced coatings, provides reliable performance across a range of materials, while the compact short-series form and FORCE-X shank ensure secure, stable operation in tight spaces and standard holders.
