Dormer Pramet A110 5.80 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 5.80 mm HSS ST straight shank long series drill (DIN 340) is built for precision, durability, and depth. Designed for professional metalworking, this drill delivers reliable holes with consistent alignment even in challenging materials.

Key features that matter in real work

• 118° conventional point creates a strong, self-centering tip that bites quickly into metal and is straightforward to re-sharpen when needed, reducing downtime.
• Steam oxide finish minimizes built-up edge by reducing the tendency of workpiece material to stick to the cutting edge, promoting cleaner holes and longer tool life.
• Long length series is purpose-built for drilling deeper holes and reaching into recessed or confined spaces where standard drills can’t reach.
• Premium HSS material handles a wide range of materials—from steel to aluminium and stainless steel—with dependable performance and reduced wear over time.
• DIN 340 compliance ensures compatibility with standard machines and holders, making this drill a dependable choice for both handheld and machine drilling setups.

This drill is ideal for metalworking professionals, machine shops, and maintenance crews who need a trustworthy, long-reach drill that performs consistently across different metals. Whether you’re creating deep pilot holes in steel, stepping into aluminium profiles, or approaching stainless steel tasks where precision matters, the A110 5.80 mm drill keeps your workpiece centered and your workflow efficient.

Practical use cases

• Drilling deep holes in steel brackets, housings, and chassis components where access is limited.
• Venturing into aluminium extrusion gaps or relatively soft stainless steel where a steady feed prevents wander.
• Maintenance tasks in confined spaces, such as vehicle frames or industrial assemblies, where a longer reach is required.

Tips for best results

• Use appropriate cutting fluid or light lubrication to prolong tool life and improve surface finish.
• Clamp workpieces securely to maintain alignment and prevent deflection during deep drilling.
• Inspect and re-sharpen when needed to preserve the drill’s 118° point geometry and cutting efficiency.
• Be mindful of drill length—long series bits can flex in thinner materials; start with a shallow hole and gradually deepen.
