Dormer Pramet A110 10.00 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 10.00 mm HSS straight shank long series drill (DIN 340) is built for serious metalworking tasks where reach and precision matter. Designed to tackle deep holes with confidence, this drill blends a robust cutting geometry with a reliable grind-friendly edge to keep you productive.

Key features that matter in real-world drilling

• 118° conventional point for strong starts, cleaner entry, and easy re-grinding when maintenance is needed. This geometry helps minimize chatter and produce true, round holes even in tougher materials.
• Steam oxide finish minimizes sticking of workpiece material to the cutting edge, improving chip flow and reducing built-up edge during longer runs.
• Long length series delivers increased reach for deeper holes and applications where sustaining access to recessed areas or through-tasks is essential.
• Premium HSS material provides dependable performance across a variety of metals—steel, aluminum, and stainless steel—without frequent tool changes.
• Straight shank compatible with standard drill chucks and collets, ensuring straightforward mounting in handheld drills or machine tools.
• DIN 340 compliance confirms consistency in size and fit, making it a reliable choice for both new tool cabinets and refurbishing existing tool inventories.
• Versatile applications suitable for workshop handheld drilling, CNC machines, and milling setups where long-reach drilling is required.

Whether you’re fabricating a frame, boring through thick material, or performing maintenance on equipment with hard-to-reach fasteners, this A110 drill helps you complete jobs faster with fewer tool changes. The 10.00 mm diameter is a common specification for structural work, tubing, and machine components, and the long-series design minimizes the need for auxiliary drilling steps.

Practical tips for best results

• Use appropriate speeds and feeds for the material—slower speeds with steady feeds for stainless steel to reduce workpiece heat.
• Peck drilling in deep holes to clear chips and maintain cutting efficiency; back off occasionally to evacuate chips.
• Keep the cutting edge clean and re-sharpen as needed to preserve the 118° point geometry and performance.
• Pair with a sharp center punch and secure workpiece clamping to minimize drift during entry.
