Dormer Pramet A110 7.50 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Introducing the Dormer Pramet A110 7.50 mm HSS ST Straight Shank Long Series Drill DIN 340 — a purpose-built long-reach drill designed for dependable performance in a range of demanding metalworking tasks. This long-series drill is engineered for deep-hole work while delivering consistent accuracy in both hand-held and machine drilling setups.

Key features include a 118° conventional point, a geometry that creates a strong, self-centering tip and is straightforward to re-grind, helping you extend tool life between sharpening sessions. The steam oxide (steam tempered) finish reduces friction and prevents workpiece material from sticking to the cutting edge, promoting cleaner holes and easier chip evacuation.

Long length for deeper holes

This is a true long-series drill with a straight cylindrical shank, purpose-built to reach deeper hole depths. The 6×D usable depth-to-diameter ratio means you can drill holes well beyond typical short bits, with reliable guidance and chip evacuation in steel and other metals. DIN 340 conformity ensures compatibility with common drill chucks and fixtures.

Premium HSS for versatile material coverage

Made from high-quality HSS (high-speed steel), the A110 long-series drill handles a variety of materials — including steel, aluminium, and stainless steel — making it a versatile addition to any workshop or production line. This combination of material and finish supports clean holes and consistent performance across different metals.

Designed for both hand-held and machine drilling

Whether you’re working at a benchtop, on a drill press, or in a CNC or robotic setup, the A110 long-series drill is optimized for hand-held and machine applications. The straight shank provides straightforward clamping and repeatable alignment, essential for repeatable hole placement in production environments.

Use cases and practical tips

• Deep-hole drilling in steel components where access is limited or where a longer reach is required without sacrificing precision.
• General-purpose drilling in aluminium and stainless steel where a robust, re-sharpenable point is advantageous.
• Maintenance and re-sharpening workflows thanks to the durable 118° point, which preserves cutting geometry with minimal profile loss during resharpening.

In short, the Dormer Pramet A110 7.50 mm long-series drill blends DIN 340 compatibility, a steam-tempered HSS construction, and a long-reach design to tackle deep holes with confidence in both manual and automated environments. For projects that demand reliable depth, clean finishes, and broad material usability, this drill stands out as a practical, high-value choice.
