Dormer Pramet A110 1.90 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Designed for precision and reach, the Dormer Pramet A110 1.90 mm HSS ST Straight Shank Long Series Drill (DIN 340) is built to tackle deeper holes without compromising alignment or edge integrity. This compact, high-performance drill blends a classic 118° conventional point with modern engineering to deliver reliable starts and long-lasting performance in a variety of materials.

Key advantages you’ll notice on the job

• 118° conventional point — provides a strong, self-centering starting edge that minimizes wandering and makes sharpening straightforward when needed.
• Steam oxide finish — reduces friction and helps prevent workpiece material from sticking to the cutting edge, promoting cleaner holes and easier chip control.
• Long length series — engineered to reach deep into workpieces and into hard-to-access areas, ideal for deep-hole drilling and applications requiring extra reach.
• Premium HSS material — versatile enough for drilling steel, aluminium, and stainless steel, delivering dependable performance across common machining tasks.
• Straight shank — compatible with a wide range of chucks and collets, delivering stable guidance in handheld and machine setups.
• DIN 340 compliance — standardizes size and fitting for predictable performance in compatible tooling ecosystems.

This drill is purpose-built for professionals who demand consistent hole quality across a spectrum of materials and applications. Whether you’re tackling a metalwork project in a workshop or performing maintenance in a production line, the A110 1.90 mm drill delivers precise hole geometry, dependable edge retention, and the versatility to adapt to both handheld and machine-driven operations.

Use cases and practical tips

• Ideal for starting holes in steel, aluminium, and stainless steel where a clean chamfer and a true diameter are critical for downstream tapping or reaming.
• Use appropriate cutting fluid or lubricant to extend drill life and manage heat, especially when drilling into tougher materials or through thicker sections.
• For deeper holes, advance gradually and use regular chip breaks to prevent clogging and maintain a smooth cutting action.
• When re-sharpening, preserve the 118° point geometry to retain accurate start conditions and hole alignment.

In short, the Dormer Pramet A110 1.90 mm HSS Straight Shank Long Series Drill combines a reliable geometry, durable coating, and extended reach to handle a wide array of drilling tasks with confidence and consistency.
