Dormer Pramet A110 1.80 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 1.80 mm HSS ST Straight Shank Long Series Drill DIN 340 is engineered for precision drilling where depth and control matter. This small-diameter drill bit pairs a robust tip with a long reach, making it a reliable choice for challenging metalworking tasks.

Its 118-degree conventional point is designed to deliver a strong, self-centering start that stays true through the cut and remains easy to re-sharpen when needed. The point geometry helps reduce wandering on initial contact, so your first hole is consistently accurate.

The steam oxide finish is more than just a surface treatment. It helps prevent workpiece material from sticking to the cutting edge, improves chip evacuation, and supports longer edge life in a variety of metals. This means smoother holes with fewer interruptions to clear chips or re-seat the drill.

Part of the long-length series, this drill is specifically designed for drilling deeper holes and reaching into tight spaces where standard-length bits can’t reach. You gain extended reach without sacrificing rigidity, so even drilling at depth stays stable and predictable.

The A110 drill uses premium high-speed steel (HSS), a versatile alloy capable of handling a range of materials—including steel, aluminium, and stainless steel. Whether you’re working on structural components, fabrications, or precision prototypes, this drill maintains sharpness and performance across common metalworking tasks.

Designed for real-world versatility, this straight-shank drill supports both handheld operation and machine-based drilling. It’s easy to swap between portable drills for on-site work and fixed fixtures in a workshop, providing consistent results across different setups.
