The Dormer Pramet A110 14.00 mm HSS straight shank long series drill (DIN 340) is purpose-built for deep-hole precision and dependable metalworking performance. Designed for durability and versatility, this drill bit is ready to tackle demanding projects in steel, aluminum, and stainless steel with consistent results.

Why this drill stands out

• 118° conventional point — a strong, self-centering tip that bites quickly into material and remains easy to re-grind for repeated use, reducing downtime on busy shop floors.
• Steam oxide finish — engineered to minimize workpiece material sticking to the cutting edge, promoting clean holes and smoother chip flow for improved efficiency.
• Long length series — optimized for drilling deeper holes and for applications where increased reach is essential, helping you access recessed work areas without compromising rigidity.
• Premium HSS material — high-speed steel construction delivers reliable performance across a broad range of metals, including steel, aluminum, and stainless steel, making it a versatile choice for mixed-material jobs.
• Straight shank — provides solid grip and compatibility with a wide range of chucks and collets, ensuring stable cutting in both handheld and machine-driven setups.
• DIN 340 conformity — built to standard dimensions for interchangeability with common tooling systems, reducing setup time and ensuring predictable fits.

Ideal applications — perfect for workshops and manufacturing environments where deep drilling is routine. Use the A110 14.00 mm drill for creating through-holes and blind holes in structural steel, aluminum components, or stainless assemblies, whether you’re working on project builds, maintenance, or prototype runs. Its long format makes it especially useful for workpieces with limited access or when a standard-length drill would be impractical.

Practical tips for best results —

• Match your spindle speed and feed rate to the material being drilled to minimize built-up edge and maximize hole quality.
• Maintain coolant or lubrication on non-ferrous or difficult steels to preserve tool life and reduce heat buildup.
• Begin with a light pilot hole if needed to ensure precise starting location, then progress to the full 14.00 mm diameter.
• Inspect the drill tip regularly and re-grind as required to sustain accurate geometry and consistent cutting performance.

Whether you’re refurbishing equipment, fabricating new components, or performing routine maintenance, the Dormer Pramet A110 14.00 mm HSS straight shank long series drill offers reliable depth capability, repeatable hole quality, and the durability you expect from a trusted brand in metalworking tooling.
