Dormer Pramet A110 3.60 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 3.60 mm HSS ST Straight Shank Long Series Drill DIN 340 is engineered for depth, durability, and precision. This long-length drill bit is purpose-built to reach deeper into workpieces without sacrificing accuracy or edge life, making it a trusted ally in fabricating, aerospace, automotive, and general workshop tasks.

Why the A110 stands out

• 118-degree conventional point: Delivers a strong, self-centering entry that’s easy to re-grind in the field, helping you maintain sharpness and reduce dwell when starting holes.
• Steam oxide finish: A smooth, oxide-coated cutting edge minimizes built-up workpiece material and improves chip flow, enhancing finish quality and reducing sticking, especially on steels and stainless steels.
• Long length series: Designed for drilling deeper holes and reaching constrained areas where a standard drill can’t reach, all while preserving rigidity and stability.
• Premium HSS material: High-Speed Steel formulation provides reliable performance across a range of materials—from mild steel and aluminum to stainless steel—with solid wear resistance and longer life under demanding conditions.
• DIN 340 compliant: This drill follows established DIN standards, ensuring compatibility with common tooling setups and predictable performance across machines and handheld drills.

Ideal applications and real-world use

• Deep-hole drilling in steel, aluminum, and stainless steel where standard-length bits fall short or require pecking and re-centering.
• Projects that demand a reliable, repeatable hole quality in applications ranging from fabrication and maintenance to prototyping and small-batch production.
• Handheld drill use for on-site jobs or bench work where access is limited and a robust, straight-shank bit can minimize deflection.
• Machine drilling where a long-reach tool boundaries the work envelope, enabling precise hole placement without repositioning the workpiece excessively.

Performance tips for best results

• Pair this drill with appropriate cutting speeds and feeds for the target material to maximize edge life and hole quality—slower feeds at higher speeds often work well for metals with this point geometry.
• Keep cutting edges clean and free of built-up material; the steam oxide finish helps, but using light lubrication or a compatibility fluid can extend tool life on tougher alloys.
• Use a pilot hole if you’re drilling a very deep hole to reduce wandering and ensure a clean entry. Maintain a steady pecking routine to clear chips and prevent binding.
• Inspect and re-sharpen the point as needed; the 118° geometry is easy to refresh, preserving hole accuracy over multiple workpieces.

Whether you’re outfitting a metalwork shop, maintaining production lines, or tackling a tough DIY project, the Dormer Pramet A110 3.60 mm HSS Straight Shank Long Series Drill DIN 340 delivers dependable performance, deep reach, and durable edge life. Its combination of a precise 118-degree point, sleek steam oxide finish, and long-reach design makes it a practical choice for professionals and serious enthusiasts who demand consistent results from a single, high-quality drill bit.
