Dormer Pramet A940 1/8 Inch HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Meet the Dormer Pramet A940 1/8 Inch HSS-E High Performance Multi-Application Straight Shank Long Series Drill (DIN/ANSI). This precision drill is engineered for reliability across a range of materials and demanding drilling tasks, delivering consistent holes with less effort and downtime.

• 130-degree point for effortless starting and self-centering. This geometry reduces push force required to begin cutting, helping you avoid wandering and produce cleaner holes from the first entry.
• Bright finish reduces chip welding and sticking. The polished edge minimizes workpiece material buildup on the cutting edge, promoting smoother entry and longer insert life.
• Parabolic flute design for deep-hole capability. Drilling deep into metallic workpieces in a single pass becomes feasible, improving cycle times and reducing tool changes in vertical or through-hole operations.
• Premium HSS-E material for versatile performance. Suitable for steels, aluminum, and stainless steel, this drill maintains rigidity and wear resistance across common machining applications.
• High-speed, high-feed capable with tight tolerances. Engineered to sustain accuracy at elevated speeds and feeds, delivering holes aligned to h10 tolerance with consistent surface finish.
• Long, straight-shank design for broad compatibility. Compatible with standard drill chucks and collets, making it a dependable choice for CNC mills, lathes, and manual machines alike.

Why choose the A940 for your workshop

When you’re stitching together aluminum components, fabricating steel brackets, or assembling stainless hardware, you need a drill that won’t slow you down. The A940’s 1/8 inch diameter is ideal for precise pilot holes, fine-tuning fits, and creating clean, deburred holes in metalwork where tolerance and finish matter most. The combination of HSS-E hardness, a self-centering point, and a flute geometry built for depth means fewer tool changes and more productive machining sessions.

Ideal use cases and materials

The A940 is well-suited for:

• Steel and stainless steel components requiring accurate hole size with minimal deflection.
• Aluminum parts where chip evacuation and edge stability are critical for high-speed drilling.
• Locking rings, brackets, enclosures, and mechanical assemblies that demand clean through-holes with tight tolerances.
• Long-hole drilling tasks where parabolic flutes help maintain chip control and straightness over depth.

Practical tips for best results

• Match speed and feed to the material: higher speeds with appropriate feeds for aluminum; balanced speeds and conservative feeds for steel and stainless to preserve edge life.
• Use light lubrication or cutting fluid on metals to reduce heat buildup and extend tool life, especially at higher speeds.
• Ensure proper workholding to minimize deflection—especially important with long-series drills when drilling deeper holes.
• Maintain the drill’s edge with periodic re-sharpening or replacement when you notice a drop in hole quality or an increase in chatter.

For workshops that demand reliability, precision, and versatility from a single drill choice, the Dormer Pramet A940 1/8 Inch HSS-E High Performance Multi-Application Straight Shank Long Series Drill stands out. It’s a practical, all-in-one solution for metal fabrication, prototyping, and production environments where hole quality, speed, and consistency are non-negotiable.
