Dormer Pramet A940 2.20 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 2.20 mm HSS-E High Perf Multi-App Straight Shank Long Series Drill (DIN/ANSI) is a purpose-built solution for engineers and machinists who demand consistent, high-precision holes across a variety of materials. Designed for reliability in both manual and CNC setups, this drill is ready to handle everything from quick pilot holes to deeper workpieces without constant tool changes.

Why this drill stands out

• 130° point for self‑centering and reduced push force: The precise point helps you start accurately on copper, steel, aluminum, or stainless components, cutting startup wander and enabling cleaner hole entry with less effort.
• Bright finish for superior chip clearance: The polished edge minimizes material adhesion, reducing built-up edge and improving surface finish on the hole walls.
• Parabolic flute design for deep-hole capability: Innovative flute geometry facilitates efficient chip evacuation, enabling deep holes in a single pass and keeping cutting temperatures in check during long drilling tasks.
• Premium HSS‑E material: High-speed steel enhanced for toughness and wear resistance, making it suitable for drilling a broad range of metals—steel, aluminum, and stainless steel—with dependable edge life.
• High-performance with tight tolerances (H10): Engineered to deliver high-quality, accurate holes even at elevated speeds and feeds, helping you meet tight dimensional requirements without rework.
• Long series with straight shank (DIN/ANSI): The straight shank design ensures broad compatibility with standard chucks and drives, while the extended length supports deeper drilling applications.
• Precise 2.20 mm diameter: Ideal for small-hole projects where accuracy and hole quality are critical, from electronics housings to precision fixtures.

Ideal use cases

• Machining small-diameter holes in steel frameworks, aluminum enclosures, and stainless assemblies where clean starts and straight, true holes matter.
• Deep-hole drilling in one pass thanks to the parabolic flute geometry, reducing cycle times and avoiding frequent re‑drilling.
• High-speed, high-feed production environments that require consistent hole quality and reliable tool life across diverse materials.

With the Dormer Pramet A940, you’re choosing a drill that blends precise geometry, resilient material science, and DIN/ANSI compatibility to deliver dependable results day in and day out. It’s the practical, high-performance choice for professional machinists who refuse to compromise on hole quality.
