Dormer Pramet A110 3/16 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 3/16 Inch HSS Straight Shank Long Series Drill (DIN 340)—a precision drill bit built for deeper holes and demanding metalworking tasks. This 3/16" diameter drill delivers steady, reliable performance across a range of materials, making it a go-to choice for shop-floors, fabrication benches, and DIY setups where reach and precision matter.

• 118-degree conventional point provides a strong, self-centering entry that stays true through the cut and is easy to re-grind for extended use.
• Steam oxide finish minimizes material sticking to the cutting edge, promotes clean chip flow, and reduces built-up edge for smoother drilling.
• Long length series offers increased reach for deep holes and hard-to-reach pockets without sacrificing rigidity or accuracy.
• Premium HSS material stands up to a variety of metals, including steel, aluminium, and stainless steel, delivering dependable performance in everyday and industrial applications.
• Straight shank, DIN 340 compatibility ensures broad fitment with common chucks and machines, delivering consistent torque transfer and reduced runout.
• Versatility for handheld and machine use—from portable drills to fixed machines—making it a flexible choice for technicians, engineers, and hobbyists alike.

Why this drill stands out: the A110 line is tuned for deep-hole drilling where standard-length bits fall short. The combination of a robust point, reduced chip sticking, and a long reach means fewer bit changes and smoother operation in steel frames, aluminum profiles, and light stainless workpieces. When you’re drilling through thicker materials or navigating tight cavities, this drill bit maintains control and consistency from start to finish.

Practical tips for best results

• Start with a light pilot hole to establish a clean path, then feed steadily to maintain concentricity.
• Use appropriate cutting fluid or light lubrication to reduce heat and extend edge life.
• Turn to moderate speeds suitable for the material being drilled to avoid overheating the HSS.
• Keep the drill steady and perpendicular to the work surface for accurate hole alignment.

Whether you’re a professional fabricator, a maintenance technician, or a dedicated maker, the Dormer Pramet A110 3/16 Inch HSS Straight Shank Long Series Drill delivers dependable depth, consistent results, and lasting value in a single, versatile tool.
