The Dormer Pramet A940 7.30 mm HSS-E High Perf Multi-App Straight Shank Long Series Drill (DIN/ANSI) is engineered for precision, durability, and multi-material versatility in demanding metalworking environments. If you routinely switch between steel, aluminum, and stainless steel, this drill is designed to keep you productive with fewer tool changes and consistent hole quality.

Key features that drive real-world results

• 130-degree point for effortless self-centering and reduced push force, helping you start holes more accurately and with less operator effort.
• Bright finish minimizes workpiece material from sticking to the cutting edge, reducing chip buildup and improving clean, consistent starts.
• Parabolic flute design enables deeper holes in a single pass, cutting through material efficiently without the need to retract or re-spot.
• Premium HSS-E material delivers reliable performance across a broad range of materials—from plain steel and aluminum to stainless steel, making it a true multi‑application drill.
• Long series with straight shank offers compatibility with standard DIN/ANSI tooling systems and collets, delivering rigidity and control for extended reach drilling tasks.
• High-speed, high-precision drilling capable of delivering accurate hole quality at elevated speeds and feeds, with tolerances aligned to H10 specifications for critical applications.

Why it matters for your workshop

When your projects demand holes that are true, straight, and repeatable across multiple materials, the A940 excels. The combination of a precise 130-degree point and a parabolic flute design reduces wandering and allows deeper penetration in a single pass—minimizing cycle times and improving throughput in production or prototyping runs.

Ideal use cases

• General-purpose drilling in steel, aluminum, and stainless steel for fabrication, automotive components, and machinery housings.
• Depth-intensive drilling tasks where hole depth approaches or exceeds standard drilling length, thanks to the parabolic flute geometry.
• Applications requiring DIN/ANSI compliant tooling with a reliable straight-shank interface for rigid performance in milling machines, drill presses, or CNC setups.

Pro tips for best results

• Use appropriate coolant or cutting fluid to maximize tool life when drilling metals prone to workpiece built-up edge.
• Securely clamp workpieces to minimize deflection and ensure concentric holes, especially on thin or flexible materials.
• Match speeds and feeds to the material being drilled, starting slower on tough steels and increasing gradually for clean hole finishes.
• Inspect the drill tip and flute condition regularly; a sharp edge maintains accuracy and reduces the need for rework.

Durability meets multi-material versatility The Dormer Pramet A940 is designed to be your go-to solution when you need one drill that delivers dependable performance across a range of common metals without swapping tooling mid-project.
