Dormer Pramet A110 6.80 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 6.80 mm HSS ST Straight Shank Long Series Drill, DIN 340. Built for reliability in metalworking, this drill delivers consistent hole quality across a range of materials while earning a reputation for longevity in demanding environments.

Key features that matter in practice

• 118° conventional point: A robust point geometry that bites quickly, minimizes wandering, and is easy to re-sharpen in-house. This translates to accurate starts and cleaner holes with less rework.
• Steam oxide finish: A protective oxide that reduces built-up edge and sticking of workpiece material at the cutting edge, helping chips flow smoothly and extending tool life during repetitive drilling cycles.
• Long length series: Designed for deeper holes and applications where reach matters. The extended flute length provides ample clearance for through-holes, pocket drilling, and work on thicker material.
• Premium HSS material: High-speed steel composition delivers solid performance across a variety of metals, including steel, aluminium, and stainless steel, with dependable hardness and heat resistance under typical drilling conditions.
• Straight shank, DIN 340: Universal compatibility with a wide range of chucks and machine spindles, ensuring quick setup in both handheld and benchtop drilling contexts.
• Versatile application: A single drill that handles multiple materials and setups—from manual drilling in the workshop to machine-driven operations—without the need for multiple tool changes.

Material compatibility and practical use

This 6.80 mm HSS drill is well-suited for drilling through steel, aluminium, and stainless steel. Its long-series design makes it a go-to choice when you need to reach recessed holes, work through thick plates, or access internal features where standard-length bits fall short. The combination of a sturdy 118° point and the steam oxide finish helps you achieve precise starts and consistent hole diameters with fewer adjustments.
