Meet the Dormer Pramet A110 16.00 mm HSS straight-shank long-series drill, a purpose-built solution for precision engineering tasks where reach and reliability matter. This DIN 340 drill is designed to deliver consistent hole quality across a range of materials, making it a trusted choice for shop floors and professional workshops alike.

Unmatched reach, uncompromised accuracy

The long-length series is purposefully engineered for drilling deeper holes and accessing cavities or thick workpieces where standard drills fall short. With a 16 mm diameter, it powers through generous material sections while maintaining straight, true hole alignment essential for fasteners, fixtures, and assemblies.

Key design advantages that matter in real work

• 118-degree conventional point: A robust cutting tip that initiates cleanly, reduces wandering, and is simple to re-sharpen when wear takes its toll, keeping downtime and tooling costs down.
• Steam oxide finish: A low-friction, anti-adhesion coating that helps prevent workpiece material from sticking to the edge, improving chip control and reducing built-up edge during heavy cuts.
• Premium HSS material: High-speed steel known for durability and wear resistance, capable of drilling a variety of metals including steel, aluminium, and stainless steel without sacrificing edge retention.
• Straight shank: Compatible with a wide range of handheld drills and machine chucks, delivering stable runout and consistent hole geometry across both portable and fixed setups.
• DIN 340 standard: Ensures interchangeability with holders and adapters that reference this common specification, simplifying tool management in busy workshops.

Versatility in action

Whether you’re assembling automotive brackets, fabricating steel frames, creating access holes in machinery, or preparing pilot holes for large-diameter fasteners, this drill provides dependable performance. Its long form shines in setups where space is limited or where workpieces are thick—without sacrificing hole concentricity or surface finish.

Why this drill fits your workflow

• Compatibility: Works with standard drill chucks and machine spindles, making it a seamless addition to both manual and automatic drilling operations.
• Durability and value: The combination of a tough HSS core, a re-sharpenable 118° point, and a finish designed to reduce sticking translates into longer tool life and more productive cutting cycles.
• Material versatility: A110 handles steel, aluminium, and stainless steel with reliable performance, giving you one drill bit that covers multiple job sites.

Practical tips for best results

• Use appropriate cutting speeds and feeds for the material to maximize tool life and hole quality; when drilling stainless steel, moderate speeds and ample lubrication help prevent work-hpiece galling.
• Maintain a steady, perpendicular drilling approach to preserve hole straightness—especially important with long-length drills in thick workpieces.
• Re-sharpen the 118-degree tip when you notice signs of dullness to extend the bit’s life and preserve edge geometry.
