Dormer Pramet A110 10.30 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Dormer Pramet A110 10.30 mm HSS ST Straight Shank Long Series Drill DIN 340 is purpose-built for demanding metalworking tasks where depth and precision matter. This long-series drill combines a robust 118° conventional point with a steam-oxide finish, delivering fast start-ups, clean holes, and dependable performance across a range of materials. Designed for both handheld and machine-operated drilling, it’s a versatile workhorse for workshops and production floors alike.

• 118-degree conventional point provides a strong, self-centering tip that bites into material quickly and remains easy to re-grind for extended tool life.
• Steam oxide finish helps reduce workpiece material adhesion at the cutting edge, promoting smoother entry and cleaner holes, especially in ferrous metals.
• Long length series offers increased reach for drilling deeper holes and access to hard-to-reach work areas without sacrificing rigidity.
• Premium HSS material supports reliable drilling across a variety of metals, including steel, aluminium, and stainless steel, making it a versatile addition to any drill assortment.
• Straight shank (ST) design ensures compatibility with a wide range of chucks, adapters, and holders, delivering secure grip and consistent performance in both manual and machine-driven setups.
• DIN 340 compatibility ensures interchangeability with standard tooling systems, simplifying replacement and maintenance in busy workshops.

This drill is ideal for professionals who need a single, reliable solution for through-hole drilling in multiple materials. Use it for quick prototyping on steel and aluminum, or in production environments where extended reach and consistent hole quality are non-negotiable. The A110 drill’s geometry is tuned for efficient chip evacuation and stable cutting, reducing dwell time and enabling faster cycle times without sacrificing accuracy.

Practical tips for maximum value:

• Clamp securely and avoid excessive feed pressure to maintain the 118° point geometry and prevent premature wear.
• Use appropriate cutting fluid or light lubrication when drilling aluminum or stainless steel to optimize edge life and finish.
• Resharpen when needed to preserve its designed point angle and overall cutting performance; a correctly re-ground point reduces walking and improves hole start accuracy.
• For deep holes, consider stepping drills or progressive drilling strategies in conjunction with the long length to minimize deflection and maintain straightness.
• Store in a dry environment to preserve the steam oxide finish and prevent corrosion, ensuring long-term tool reliability.

Whether you’re upgrading a handheld drill or equipping a CNC or manual drilling station, the Dormer Pramet A110 drill delivers dependable performance, consistent hole quality, and the versatility to handle a broad spectrum of workpiece materials. This is a thoughtful, durable choice for machinists, fabricators, and workshop technicians who value efficiency, precision, and long-term value in a single drill.
