Dormer Pramet A110 5.30 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Introducing the Dormer Pramet A110 5.30 mm HSS Long Series Drill, a precision tool built to tackle deep holes with assurance. Designed to DIN 340 standards, this drill features a robust 118° conventional point that delivers a strong bite and remains easy to re-sharpen when needed, minimizing downtime and keeping your workflow moving.

The steam oxide finish—often described as steam tempered—helps prevent workpiece material from sticking to the cutting edge, extending edge life and reducing chatter and built-up edge in demanding drilling tasks. This thoughtful finish makes the A110 a reliable choice for repetitive jobs where consistent performance matters.

Long length series are specifically engineered for increased reach, enabling deeper holes and access to tighter work areas. In practical terms, this means you can drill six times the nominal diameter (6×D) without pecking in steel, which translates to fewer tooling changes and more efficient material removal. For the 5.30 mm size, you’ll typically see an overall length around 132 mm with a flute length near 87 mm, a combination that balances rigidity with reach for challenging applications.

Crafted from premium high-speed steel (HSS), the A110 excels across a broad spectrum of materials, including steel, aluminium, and stainless steel. This versatility makes it a staple in machine shops, fab shops, and workshop environments where one drill needs to perform well on multiple substrates. Whether you’re drilling with a handheld drill or a CNC/machine setup, the A110’s straight shank provides stable guidance and predictable performance.

Who benefits most from the A110 5.30 mm long-series drill?

• Professionals who routinely drill deep holes in metal assemblies, structural components, or fabrications where reach matters.
• Maintenance shops and automotive/industrial environments that value reliable edge life, re-grindability, and consistent chip ejection.
• DIY enthusiasts tackling demanding metalworking tasks that require a single versatile tool capable of handling steel, aluminum, and stainless components.

Practical tips for best results:

• Match your feed rate and cutting speed to the material being drilled, and use steady, continuous pressure to avoid deflection on long-hole work.
• Maintain the tip integrity: the 118° point is designed for robust entry and easier re-sharpening when necessary.
• Use appropriate cooling/lubrication for metals where heat buildup is a concern to maximize tool life and hole quality.
• Ensure the drill is properly secured in a chuck or collet for straight, true hole creation, especially when working at depth with the long-length design.

With the Dormer Pramet A110, you’re choosing a long-series, straight-shank drill that combines depth capability, re-sharpening ease, and broad material compatibility into one dependable tool. It’s the practical, high-performance choice for serious metalworking tasks where precision and reach are non-negotiable.
