Dormer Pramet A110 10.75 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Introducing the Dormer Pramet A110 10.75 mm HSS ST Straight Shank Long Series Drill DIN 340—a precision drill bit designed for depth, durability, and consistent performance in a range of metals. This is the tool you reach for when you need reliable reach without sacrificing control or accuracy.

• 118‑degree conventional point delivers a strong, self‑centering bite that penetrates with minimal wandering and remains easy to re‑grind for extended life.
• Steam oxide finish reduces friction and minimizes workpiece material from sticking to the edge, promoting cleaner cuts and smoother chip evacuation.
• Long length series provides increased reach for deeper holes and applications where access is limited, while preserving rigidity and precision you expect from a drill designed for machine and handheld use.
• Premium HSS material combines toughness and heat resistance suitable for drilling a variety of metals—including steel, aluminium, and stainless steel—without compromising edge retention.
• Straight shank (ST) ensures compatibility with standard drill chucks and holders, delivering stable runout and dependable clamping in both handheld and machine environments.
• DIN 340 standard assures interchangeability and consistent performance across professional tooling setups, making it a dependable choice for workshop inventories.

Use cases you’ll appreciate: deep-hole drilling in steel chassis and frames, aluminum extrusion work, stainless components where extra reach is beneficial, and assemblies where access is restricted by surrounding structures. The A110’s design supports sustained cutting performance across a variety of jobs, reducing tool changes and downtime in busy workshops.

Practical tips for optimal results: start with a light pilot hole on harder materials to improve centering, then feed steadily to maintain a clean edge; for steel and stainless, use appropriate cutting fluid to manage heat and extend tool life; avoid forcing the bit—let the geometry do the work while you maintain steady, controlled feeds.
