Dormer Pramet A110 7/64 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 7/64 Inch HSS Straight Shank Long Series Drill (DIN 340) is your go-to solution for precise, deep-hole drilling in metal. Designed for reliability in professional shops and demanding DIY projects alike, this drill bit combines a robust cutting edge with a geometry that minimizes wandering and chatter.

Key features that matter in real-world work

• 118-degree conventional point — delivers a strong starting bite, reduces walking on initial contact, and is easy to re-sharpen for extended life in the field.
• Steam oxide finish — a protective coating that helps prevent workpiece material from sticking to the cutting edge, promoting cleaner holes and smoother chips.
• Long length series — engineered for deeper holes and applications where extended reach is essential, such as thick plates, stepped holes, or recessed work areas.
• Premium HSS material — versatile enough for drilling steel, aluminum, and stainless steel, delivering dependable performance across common metalworking tasks.
• Straight shank, DIN 340 design — compatible with a wide range of handheld drills and drill presses, ensuring consistent alignment and stability during operation.

Practical use cases

• Deep-hole drilling in automotive, fabrication, and aerospace components where standard-length bits fall short.
• General-purpose metal drilling in steel, aluminum, and stainless steel with reliable edge retention and clean hole quality.
• Projects that require precise hole starting and minimal wander, such as component mounting or fixture alignment.

Why this drill stands out from the rest — The A110’s combination of a durable 118° point, steam oxide finish, and long-reach geometry means you can push deeper into material with fewer interruptions, fewer bit changes, and less rework. It’s a practical upgrade for professionals who value consistency, longevity, and dependable performance in varied metalworking scenarios.

Tip: match your feed rate and spindle speed to the material you’re drilling, and use appropriate lubrication to extend life and achieve smoother entry and exit holes. For applications demanding depth, this long-series drill is a reliable partner that maintains stiffness and accuracy from the first cut to the last.
